Association Between Active Gait Training for Severely Disabled Patients with Nasogastric Tube Feeding or Gastrostoma and Recovery of Oral Feeding: A Retrospective Cohort Study

PURPOSE

This study evaluates the effect of introducing active gait training (AGT) to patients who are severely disabled with nasogastric tube feeding or gastrostoma on the recovery of oral feeding.

PATIENTS AND METHODS

We conducted a historical cohort study at a single rehabilitation center in Japan between January 2013 and December 2019. In this study, 154 severely disabled patients with nasogastric tube feeding or gastrostoma due to neurological diseases or disuse syndrome admitted in a rehabilitation ward were included, and their median age was 84 years. AGT was systematically implemented in August 2016, which consisted of using orthosis or assistance from physical therapists. We compared the recovery of oral feeding between periods before (Pre-AGT) and after (Post-AGT) the introduction of AGT.

RESULTS

Among the 154 severely disabled patients included, 59 (38%) were admitted in the Post-AGT period. Twenty-eight (30%) and 54 patients (92%) started gait training in the Pre-AGT and Post-AGT periods, respectively (p < 0.001). Significantly more patients recovered oral feeding in the Post-AGT than in the Pre-AGT periods (49% vs 19%, respectively; p < 0.001). After the introduction of AGT, the adjusted hazard ratio for the recovery of oral feeding was 4.0 (95% confidence interval, 1.9-8.3; p < 0.001).

CONCLUSION

After the introduction of AGT to patients, increased recovery of oral feeding was observed in this retrospective evaluation. AGT should be considered for patients with tube feeding to help them recover oral feeding even if patients were severely disabled and required full assistance during gait training.

Comparison of Feeding Efficiency and Hospital Mortality between Small Bowel and Nasogastric Tube Feeding in Critically Ill Patients at High Nutritional Risk

Nasogastric tube enteral nutrition (NGEN) should be initiated within 48 h for patients at high nutritional risk. However, whether small bowel enteral nutrition (SBEN) should be routinely used instead of NGEN to improve hospital mortality remains unclear. We retrospectively analyzed 113 critically ill patients with modified Nutrition Risk in Critically Ill (mNUTRIC) score ≥ 5 and feeding volume < 750 mL/day in the first week of their stay in the intensive care unit (ICU). Age, sex, mNUTRIC score, and Acute Physiology and Chronic Health Evaluation II (APACHE II) score were matched in the SBEN (n = 48) and NGEN (n = 65) groups. Through a univariate analysis, factors associated with hospital mortality were SBEN group (hazard ratio (HR), 0.56; 95% confidence interval (CI), 0.31-1.00), Simplified Organ Failure Assessment (SOFA) score on day 7 (HR, 1.12; 95% CI, 1.03-1.22), and energy intake achievement rate < 65% (HR, 2.53; 95% CI, 1.25-5.11). A multivariate analysis indicated that energy intake achievement rate < 65% on the third follow-up day (HR, 2.29; 95% CI, 1.12-4.69) was the only factor independently associated with mortality. We suggest initiation of SBEN on the seventh ICU day before parenteral nutrition initiation for critically ill patients at high nutrition risk.

Delayed Resolution of Feeding Problems in Patients With Congenital Hyperinsulinism

Background: Congenital Hyperinsulinism (CHI) is the most common cause of recurrent and severe hypoglycaemia in childhood. Feeding problems occur frequently in severe CHI but long-term persistence and rates of resolution have not been described. Methods: All patients with CHI admitted to a specialist center during 2015-2016 were assessed for feeding problems at hospital admission and for three years following discharge, through a combination of specialist speech and language therapy review and parent-report at clinical contact. Results: Twenty-five patients (18% of all patients admitted) with CHI were prospectively identified to have feeding problems related to sucking (n = 6), swallowing (n = 2), vomiting (n = 20), and feed aversion (n = 17) at the time of diagnosis. Sixteen (64%) patients required feeding support by nasogastric/gastrostomy tubes at diagnosis; tube feeding reduced to 4 (16%) patients by one year and 3 (12%) patients by three years. Feed aversion resolved slowly with mean time to resolution of 240 days after discharge; in 15 patients followed up for three years, 6 (24%) continued to report aversion. The mean time (days) to resolution of feeding problems was lower in those who underwent lesionectomy (n = 4) than in those who did not (30 vs. 590, p = 0.009) and significance persisted after adjustment for associated factors (p = 0.015). Conclusion: Feeding problems, particularly feed aversion, are frequent in patients with CHI and require support over several years. By contrast, feeding problems resolve rapidly in patients with focal CHI undergoing curative lesionectomy, suggesting the association of feeding problems with hyperinsulinism.

The Safety and Efficacy of Procedureless Gastric Balloon: a Study Examining the Effect of Elipse Intragastric Balloon Safety, Short and Medium Term Effects on Weight Loss with 1-Year Follow-Up Post-removal

INTRODUCTION

The Ellipse intragastric balloon (EIGB) is a new swallowable balloon that does not require endoscopy at insertion or removal. The aim of this study is to investigate the safety of EIGB and its efficiency in weight reduction even after 1 year of expulsion.

METHOD

Prospective study on our initial experience with a consecutive group of patients who underwent the insertion of EIGB in the period between September 2016 and February 2017. The patients were followed up to assess pain, nausea, and vomiting after procedure. As well as, the time of balloon extraction, route of extraction, and weight loss.

RESULTS

Total of 112 patients underwent EIGB placement. A 1-year follow-up was obtained on 85% of patients. Mean weight and BMI before the procedure 92.2 kg and 34.3 kg/m², respectively. One patient had small bowel obstruction. Six patients did not tolerate EIGB and three patients had early deflation. Total weight loss % (TWL%) 10.7, 10.9, and 7.9% at 3, 6, and at date of last follow-up. When data were stratified according to BMI into two groups: group 1 (BMI 27.5-34.9) and group 2 (BMI 35-49), the TWL% for group 1 at 3 months, 6 months, and last day of follow-up are as follows: 10.2%, 10.6%, and 8.8%, while it was 11.5%, 11.2%, and 6.6% for group 2.

CONCLUSION

EIGB are effective, safe, and feasible non-invasive method for weight loss.

Preoperative Educational Intervention Decreases Unplanned Gastrostomy-Related Health Care Utilization

Apprehension in taking independent care of children with medical devices may lead to unnecessary visits to the ED and/or acute clinic (AC). To address these concerns, our institution implemented a gastrostomy tube (GT) class in 2011 for caretakers. We hypothesized that inappropriate GT-related ED/AC visits would be lower in preoperatively educated caregivers. We performed a retrospective cohort study of all patients aged 0 to 18 who received GT (surgical or percutaneous) at our institution between 2006 and 2015 (n = 1340). Class attendance (trained vs untrained) and unscheduled GT-related ED/AC visits one year after GT placement were reviewed. Gastrostomy-related ED/AC visits were classified as appropriate (hospital-based intervention) or inappropriate (site care and education/reassurance). Occurrence of ED/AC visits was compared between trained and untrained cohorts. We found that 59 per cent of patients had an unscheduled GT-related ED/AC visit within one year of placement. The trained cohort had 27 per cent less unplanned ED/AC visits within one year (mean 1.21 (SD 1.82) vs untrained 1.65 (2.24), P < 0.001). On multivariate analysis, GT education independently decreased one-year GT-related health care utilization (Odds Ratio 0.75, 95% Confidence Interval 0.59-0.95). Formal education seems to decrease GT-related health care utilization within one year of placement and should be integrated into a comprehensive care plan to improve caregiver self-efficacy.

Advance Directives and End-of-Life Care among Nursing Home Residents Receiving Maintenance Dialysis

BACKGROUND AND OBJECTIVES

Little is known about the relation between the content of advance directives and downstream treatment decisions among patients receiving maintenance dialysis. In this study, we determined the prevalence of advance directives specifying treatment limitations and/or surrogate decision-makers in the last year of life and their association with end-of-life care among nursing home residents.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Using national data from 2006 to 2007, we compared the content of advance directives among 30,716 nursing home residents receiving dialysis to 30,825 nursing home residents with other serious illnesses during the year before death. Among patients receiving dialysis, we linked the content of advance directives to Medicare claims to ascertain site of death and treatment intensity in the last month of life.

RESULTS

In the last year of life, 36% of nursing home residents receiving dialysis had a treatment-limiting directive, 22% had a surrogate decision-maker, and 13% had both in adjusted analyses. These estimates were 13%-27%, 5%-11%, and 6%-13% lower, respectively, than for decedents with other serious illnesses. For patients receiving dialysis who had both a treatment-limiting directive and surrogate decision-maker, the adjusted frequency of hospitalization, intensive care unit admission, intensive procedures, and inpatient death were lower by 13%, 17%, 13%, and 14%, respectively, and hospice use and dialysis discontinuation were 5% and 7% higher compared with patients receiving dialysis lacking both components.

CONCLUSIONS

Among nursing home residents receiving dialysis, treatment-limiting directives and surrogates were associated with fewer intensive interventions and inpatient deaths, but were in place much less often than for nursing home residents with other serious illnesses.

Impact of an enhanced recovery after surgery programme in radical cystectomy. A cohort-comparative study

OBJECTIVE

To evaluate the results of the implementation of an enhanced recovery program (ERAS) for open approach radical cystectomy compared to the historical cohort of the same hospital.

MATERIAL AND METHODS

A retrospective analysis of 138 consecutive patients who underwent radical cystectomy with Bricker or Studer ileal derivation (97 historical vs. 41 ERAS). Overall complication rate, Clavien-Dindo stage>2 complications, mortality, hospital and critical care length of stay and readmission rates, as well as need for reoperation, nasogastric intubation, transfusion or parenteral nutrition were compared.

RESULTS

No statistically significant differences in overall complication rate were found (73.171 vs. 77.32%; OR 1.25, 95% CI 0.54-2.981; P=.601) nor in Clavien-Dindo>2 complications (41.463 vs. 42.268%; OR 1.033, 95% CI 0.492-2.167; P=.93), mortality, lengths of stays readmission and reoperation rates. The need for nasogastric tube insertion was lower in the ERAS group (43.902 vs. 78.351%; OR 4.624, 95% CI 2.112-10.123; P<.0001), as well as the need for total parenteral nutrition (26.829 vs. 34.021%; OR 12.234, 95% CI 5.165-28.92; P<.0001), and time under endotracheal intubation since anaesthesia induction (median [IRQ]=325 (285-355) vs. 540 (360-600) min; P<.0001).

CONCLUSION

Enhanced recovery programs in radical cystectomy decrease interventionism on the patient without increasing morbidity and mortality.

Enteral nutrition at home and in nursing homes: an 11-year (2002-2012) epidemiological analysis

BACKGROUND

Home enteral nutrition (HEN) is a well-established extra-hospital therapy that can reduce the risk of malnutrition, ensure the rapid discharge of patients from hospital and significantly reduce health care expenditure. The data reported in this study allow us to understand the relationships between mortality, the place of treatment either at patients' homes (PH) or in nursing homes (NHR) and nutritional status.

METHODS

Patients were analyzed according to age, gender, underlying disease, the Karnofsky Index, type of enteral access device (nasogastric tube or percutaneous endoscopic gastrostomy), weight and Body Mass Index (BMI). The duration of HEN therapy was then calculated and the outcome was established on patient mortality or survival.

RESULTS

Over an 11-year period, 3246 subjects were administered HEN therapy. The mean duration of HEN therapy was equal to 312±487 days at PH and 398±573 in NHR. The mean incidence is 406±58 patients/million inhabitants/year at PH and 319±44 in NHR (mean prevalence rate: 464±129 cases/million inhabitants at PH compared to 478±164 in NHR). Analysis of variance was used for continuous variables. The study reveals that >8% (8.6% at PH; 8.5% in NHR) of patients die within 10 days of starting HEN therapy.

CONCLUSIONS

The study shows a progressive increase in HEN therapy and highlights clinical, organizational and ethical issues, which also need to be analyzed in relation to the progressively aging population.

Can't swallow, can't transfer, can't toilet: factors predicting infections in the first week post stroke

Post stroke infections are a significant clinical problem. Dysphagia occurs in approximately half of stroke patients and is associated with respiratory infections; however it is unclear what other factors contribute to an increased risk. This study aimed to determine which factors are most strongly predictive of infections in the first 7 days post stroke admission. A retrospective review of 536 stroke patients admitted to Australian hospitals in 2010 was conducted. Data were collected on 37 clinical and demographic parameters. Univariate and multivariate logistic regression analysis was performed. The overall incidence of infection was 21%. Full assistance with mobility and incontinence on admission were associated with increased odds of general infection. Nil by mouth and presence of a nasogastric tube were significantly associated with patients developing respiratory infections. Urinary incontinence was a significant predictor for a urinary tract infection. Incidence of infection was highest on day two post admission. This study found enteral feeding, requiring full assistance with mobility and incontinence were significantly associated with developing infections in acute stroke. It contributes valuable new data from a large cohort of stroke patients demonstrating a period of susceptibility to infection in the very acute post stroke period.

Feeding tubes and health costs postinsertion in nursing home residents with advanced dementia

CONTEXT

The best evidence suggests that feeding tubes are ineffective in persons with advanced dementia. Little is known about their health care costs.

OBJECTIVES

To estimate Medicare costs attributable to inpatient care among nursing home (NH) residents with advanced dementia during the year following the placement of a percutaneous endoscopic gastrostomy (PEG) tube during an index hospitalization.

METHODS

Medicare claims (1999-2009) and Minimum Data Set data (1999-2009) were used to estimate Medicare costs attributable to inpatient care among NH residents with advanced dementia during the year following the placement of a PEG tube and compared with those who did not get a PEG tube. The study used a 3:1 propensity-matched cohort design.

RESULTS

Matched residents with (n=1924, 68.9% female, 28.8% African American, average age 83.1 years) and without (weighted n=1924, unique n=4337) PEG insertion showed comparable sociodemographic characteristics, similar rates of feeding tube risk factors, and similar mortality (51.9% 180 day mortality among those with a feeding tube vs. 49.8% among those without a feeding tube, P=0.11). One year hospital costs were $2224 higher in NH residents with a feeding tube ($10,191 vs. $7967, 95% CI of difference=$1514, $2933), with those with a feeding tube likely to spend more time in an intensive care unit (1.92 vs. 1.29 days, 95% CI of difference=0.34, 0.92 days).

CONCLUSION

In an analysis controlling for selection bias, PEG tube insertion is associated with a small but significant increase in annual inpatient health care costs, as well as in hospital and intensive care unit days, postinsertion.

Percutaneous endoscopic gastrostomy (PEG) tubes are placed in elderly adults in Japan with advanced dementia regardless of expectation of improvement in quality of life

BACKGROUND

The Japan Geriatrics Society published a guideline on the decision-making process for health care for the elderly in June 2012, noting that withholding or withdrawing feeding tubes are treatment options that should be discussed during the decision-making process. Arguments against the guideline posit that the insertion of a percutaneous endoscopic gastrostomy (PEG) tube feeding may improve quality of life (QOL) for elderly adults and their relatives.

OBJECTIVES

The aim of the present study was to explore (a) expected outcomes with PEG tube placement and (b) outcomes from PEG tube feeding in long-term care settings among elderly adults with advanced dementia in Japan.

DESIGN

This study was conducted using a cross-sectional study design.

SETTING

A total of 381 hospitals and 985 long-term care facilities provided sets of completed questionnaires.

PARTICIPANTS

There were 1 199 hospital patients and 2 160 long-term care patients aged 65 years or older with PEG tube placement included in the analysis.

MEASUREMENTS

The nurses or physicians at each hospital provided information on the level of dementia at the time of PEG tube placement and on the expected outcomes of PEG tube feeding for elderly hospital patients. The nurses or other direct care workers at each facility provided information on the level of dementia and outcomes from PEG tube feeding for the long-term care patients.

RESULTS

In the hospital patient group, 62.9% of patients had advanced dementia. PEG tube feeding was expected to prolong survival for 51.1% of hospital patients with advanced dementia. Improved QOL was expected for 39.1% of them. In the long-term care patient group, 61.7% of patients had advanced dementia. The rate of patients enjoying their own lives was lower in long-term care patients who had advanced dementia (4.2%) than in the other patients (16.4%). Approximately 60% of relatives reported satisfaction with the QOL of the patients, both in the long-term care patients with advanced dementia and the other patients.

CONCLUSION

Our results question the assumption that PEG tube feeding may improve QOL among elderly adults with advanced dementia. The national health policy should explore an approach to help patients, relatives, and practitioners make decisions about feeding options.

[Risk factors of nasogastric tube placement after elective colorectal surgery included in a rehabilitation programme: a multivariate analysis]

OBJECTIVE

Nasogastric tube placement (NTP) is no more systematically recommended in patients scheduled for elective colorectal surgery but could be necessary in case of postoperative vomiting. The aim of this study was to determine independent risk factors for NTP after colorectal surgery.

PATIENTS AND METHODS

We performed an observational study including 290 patients scheduled for elective colorectal surgery included in an enhanced recovery programme: immunonutrition, thoracic epidural analgesia, antiemetic prophylaxis, respiratory physiotherapy, absence of NT and drainage, forced mobilization and oral nutrition. The main outcome was the occurrence of vomiting requiring NTP. Univariate analysis included: age, sex, BMI, American Society of Anesthesiologist Physical Status Classification System (ASA), duration of surgery, epidural analgesia, and mobilization, intraoperative fluid, temperature, laparotomy, use of droperidol, parenteral nutrition, stoma, diabetes, hypertension or coronary disease, COPD, type of surgery. A logistic regression was performed to determine independent risk factors of NTP.

RESULTS

Among the 290 patients included, 277 were analyzed. The incidence of NTP was 10.5% (95%CI [7.4-14.6%]). Univariate analysis documented BMI, low temperature in PACU (<35°C), ASA scores, duration of surgery and epidural analgesia, rectal and sigmoid resections, diabetes, transfusion, no use of droperidol, duration of mobilization, conversion to laparotomy. Three independent risk factors were associated with NTP: temperature in SSPI<35.5°C (OR: 14.49; IC95% [4.52-45.45], P<0.0001), BMI<21kg/m(2) (8.40; [1.99-35.71], P=0.0038) and lack of postoperative droperidol administration (3.37 [1.02-11.39], P=0.04).

CONCLUSIONS

After colorectal surgery tolerance to rapid oral feeding is impaired by denutrition and postoperative hypothermia. The combined used of postoperative droperidol should also be considered to avoid postoperative NTP.

Quality and safety issues in procedural rural practice: a prospective evaluation of current quality and safety guidelines in 3000 colonoscopies

INTRODUCTION

Colonoscopy remains the gold standard for the investigation and management of bowel pathology. A 2009 National Bowel Cancer Screening Program Quality Working Group report revealed that small rural towns in inner regional Victoria, Australia, for example Echuca (Rural and Remote Metropolitan Areas [RRMA] 4), registered 10.5 colonoscopies per 1000 population versus 18.5 per 1000 in the state capital Melbourne. Reasons for this discrepancy include lack of skilled practitioners in rural communities and travel time for patients to attend larger centres when the required bowel preparation or mobility issues limit access. Ideally, services are high quality, safe and local. This study assessed the quality and safety of a rural GP colonoscopy service.

METHODS

The indications, findings, caecal intubation rates, complications and completion time were recorded for 3000 serial colonoscopies performed by one rural procedural GP from 1995 to 2011 in Victorian Echuca. Quality was assessed using caecal intubation rate, polyp and colorectal carcinoma detection rates, and completion time. Safety was determined by complication rates.

RESULTS

The caecal intubation rate was 97% (excluding stenosing lesions), polypectomy detection rate was 39%, carcinoma detection rate was 2%, and the average time to completion was 17 min. Re-admission rates were 1.6/1000 for haemorrhage and 1.2/1000 for perforation. There were no deaths.

CONCLUSIONS

The results from this study compare favourably with published international standards, validate Australian general practice procedural training standards, and validate the additional quality measure of 'colonoscopy completion time'. Rural GPs can provide a safe and high quality service. Extending this service model to similar settings could improve reduced access to colonoscopy for rural Australians.

Nasogastric tube use in children after abdominal surgery- how long should it be kept in Situ?

BACKGROUND

Traditionally, the use of a nasogastric tube (NGT) after a laparotomy is said to prevent vomiting, aspiration, abdominal distension and paralytic ileus, which are likely to complicate the postoperative course.

OBJECTIVE

To determine if discontinuation of NGT within 24 hours of abdominal surgical procedures in children has any effect on postoperative recovery.

MATERIALS AND METHODS

We prospectively studied children who needed NGT passed for abdominal surgical procedures. NGTs were removed within 24 hours in all but 46 children who had the tube in situ for 3 to 5 days. Time to first and full oral feeds, length of hospital stay and complications were compared between the groups.

RESULTS

Children who had their NGTs removed within 24 hours (N = 120, Group 1) were compared with those who had NGT in place for 3 to 5 days (N = 46, Group 2). The mean time to first oral sips was 1.02 ± 0.13 days for Group 1 and 3.09 ± 0.29 days for Group 2 (p = 0.001). The mean time to full feeding was 2.22 ± 0.54 days for Group 1 and 4.54 ± 0.55 days for Group 2 (p = 0.001). Mean length of hospital stay (LOHS) was 8.32 ± 5.49 days for Group 1 and 12.78 ± 8.79 days for Group 2 (p = 0.001). Mean LOHS was 9.55 ± 6.85 days for both groups combined. Ten complications associated with the removal of the NGT occurred in both groups- 6 in Group 1 and 4 in Group 2 (p = 0.37). These were mainly vomiting and abdominal distension.

CONCLUSION

Our findings suggest that routine use of NGTs for decompression after laparotomy may be safely dispensed with after the child has recovered from anaesthesia.

[National registry of home enteral nutrition in Spain 2007]

OBJECTIVE

To communicate the results from the registry of Home-Based Enteral Nutrition of the NADYASENPE group in 2007.

MATERIAL AND METHODS

We included every patient in the registry with home enteral nutrition any time from January 1st to December 31st of 2007.

RESULTS

The number of patients with home enteral nutrition in 2007 was 5,107 (52% male) from 28 different hospitals. 95.4% of them were 15 yr or older, with a mean age of 67.96 +/- 18.12, and 4.2 +/- 3.38 among patients aged 14 yr or less. The most common underlying diseases were neurological (37.8%) and neoplastic diseases (29.3%). Enteral nutrition was administered p.o. in most patients (63.5%), followed by nasogastric tube (25.9%), while gastrostomy was only used in 9.2%. The mean time in enteral nutrition support was 9.4 months and the most common reasons for withdrawal were death (58.7%) and switching to oral intake (32%). Activity was limited in 31.4% of patients and 36.01% were house-bound. Most patients needed partial (26.51%) or total (37.68%) care assistance. Enteral formula was provided by hospitals to 69.14% of patients and by pharmacies to 30.17% of them, while disposable material was provided by hospitals to 81.63% and by Primary Care to the remaining patients.

CONCLUSIONS

In 2007, there has been an increase of more than 30% of patients registered with home enteral nutrition comparing with 2006, without any big difference in other data, but a higher proportion of patients with enteral nutrition p.o.

Demographic, epidemiological and nutritional profile of elders using home enteral nutritional therapy in Distrito Federal, Brazil

According to statistical projections of the World Health Organization, during the period between 1950 and 2025, the group of elderly in Brazil will have increased 15 times. Chronic-degenerative diseases are the illnesses that most affect the elderly population, directly related to the growing demand for Enteral Nutrition Therapy. The objective of this study was to analyze the demographic, epidemiological and nutritional profile of elderly patients assisted at the public hospitals in the Home Enteral Nutrition Therapy Program, of the State Health Department of Distrito Federal. This is a retroprospective, cross-sectional and analytical study, based on primary data, which enrolled 141 elderly patients who were prescribed home enteral nutrition. The collected variables corresponded to age, gender, clinical diagnosis, enteral route and nutritional status at the beginning of Home Enteral Nutrition Therapy. The association between variables was analyzed through the t-Student and chi-square tests, with a significance level of 0.05 and a Confidence Interval (CI) of 95%. There was a higher number of female patients (53.9%) when compared to male (46.1%), average age 75.82 years old for both groups. The most prevalent diseases were cerebro-vascular accident sequels and cancer (42.6% and 22.7% respectively). It was observed a prevalence of malnutrition equal to 69.7%, independent of age and gender. The most used enteral route was the nasal. Though Brazilian policies concerning assistance to the elderly have advanced during the last few years, the need for public policies for nutritional recovery of such patients persists, to promote a better quality of life for them.

Can surgeon familiarization with current evidence lead to a change in practice? A prospective study

BACKGROUND

Despite evidence against its utility, many surgeons continue to employ prophylactic nasogastric decompression in elective colonic resection. This study aimed to establish whether an easy and practical intervention, mailing out a summary of current evidence to surgeons, can change surgeons practice to bring it more in line with current evidence.

METHODS

The use of prophylactic nasogastric (NG) decompression in elective colonic resections was documented for the 2 consecutive months of October and November, 2004 at the Royal Alexandra Hospital (RAH). A one page summary of recent evidence concerning this practice was then mailed to all general surgeons at that institution. A similar second review was carried out for the months of January and February, 2005. The two periods were compared with regards to prophylactic NG use.

RESULTS

Twenty two patients underwent elective colonic resections during the months of October and November, 2004. Twenty one patients underwent such procedures in January and February, 2005. Seven out of the 22 cases in the first group (the pre-intervention block) received prophylactic NG decompression. Five out of the 21 cases in the second group (the post-intervention block) received prophylactic NG decompression. The difference in prophylactic NG use between the two groups was not statistically significant.

CONCLUSIONS

This study has shown that mailing out a summary of current evidence to surgeons concerning a certain issue is not sufficient to lead to a change in practice.

Nasogastric tube feeding in predicted severe acute pancreatitis. A systematic review of the literature to determine safety and tolerance

CONTEXT

Nasogastric tube feeding is safe and well tolerated in most critically ill patients. However, its safety and tolerance in the setting of severe acute pancreatitis is debatable.

OBJECTIVE

We aimed to review all available studies on nasogastric feeding in patients with severe acute pancreatitis to determine the safety and tolerance of this approach. A further aim was to perform a meta-analysis of the available randomized controlled trials regarding nasogastric versus nasojejunal feeding.

METHODS

Three electronic databases (Cochrane Central Register of Controlled Trials, EMBASE and MEDLINE) and the abstracts of major gastroenterological meetings were reviewed. Meta-analysis was performed using the random effects model.

MAIN OUTCOME MEASURES

The summary estimates were reported as risk ratio (RR) with 95% confidence interval (95% CI).

RESULTS

A total of four studies on nasogastric tube feeding in 92 patients with predicted severe acute pancreatitis were identified. Documented infected pancreatic necrosis developed in 11 patients (16.9%) and multiple organ failure in 10 (15.4%) out of 65 patients with available data. Overall, there were 15 deaths (16.3%). An exacerbation of pain after initiation of feeding occurred in 3 (4.3%) out of 69 patients with available data. Full tolerance was achieved in 73 (79.3%) patients who did not require temporary reduction, stoppage or withdrawal of nasogastric feeding. The results of nasogastric feeding as compared to nasojejunal feeding, were no worse in terms of mortality (RR=0.77; 95% CI: 0.37 to 1.62; P=0.50) or intolerance of feeding (RR=1.09; 95% CI: 0.46 to 2.59; P=0.84).

CONCLUSION

Nasogastric feeding appears safe and well tolerated in patients with predicted severe acute pancreatitis. An adequately powered randomized trial on nasogastric versus nasojejunal feeding is required to support this approach as routine clinical management.

[Performance analysis of venous puncture, and nasogastric and nasointestinal tube placement in a pediatric ward]

This article is an observational study that analyzes the performance of venous punctures and nasogastric and nasointestinal tube placement in pediatric patients, performed by nurses in a pediatric ward. This exploratory descriptive study was carried out at a teaching hospital in Porto Alegre, Rio Grande do Sul, Brazil, and its purpose is to identify frequency and time spent in the performance of these procedures, as well as to provide data for the management of nursing human resources. Two nurses were selected intentionally and an observation structured record was used to collect the data. The average time spent in the performance of venous punctures was 17.62 minutes, and tube placement, 10.8 minutes. The outcomes provided an understanding of the processes complexity, whose elements are related to the nurse's work process, as well as to the other professionals involved, the family and the child who underwent the procedures.

Tracheal intubation in the emergency department: the Scottish district hospital perspective

BACKGROUND

Tracheal intubation is the accepted gold standard for emergency department (ED) airway management. It may be performed by both anaesthetists and emergency physicians (EPs), with or without drugs.

OBJECTIVE

To characterise intubation practice in a busy district general hospital ED in Scotland over 40 months between 2003 and 2006.

SETTING

Crosshouse Hospital, a 450-bed district general hospital serving a mixed urban and rural population; annual ED census 58,000 patients.

METHODS

Prospective observational study using data collection sheets prepared by the Scottish Trauma Audit Group. Proformas were completed at the time of intubation and checked by investigators. Rapid-sequence induction (RSI) was defined as the co-administration of an induction agent and suxamethonium.

RESULTS

234 intubations over 40 months, with a mean of 6 per month. EPs attempted 108 intubations (46%). Six patients in cardiac arrest on arrival were intubated without drugs. 29 patients were intubated after a gas induction or non-RSI drug administration. RSI was performed on 199 patients. Patients with trauma constituted 75 (38%) of the RSI group. 29 RSIs (15%) were immediate (required on arrival at the ED) and 154 (77%) were urgent (required within 30 min of arrival at the ED). EPs attempted RSI in 88 (44%) patients and successfully intubated 85 (97%). Anaesthetists attempted RSI in 111 (56%) patients and successfully intubated 108 (97%). Anaesthetists had a higher proportion of good views at first laryngoscopy and there was a trend to a higher rate of successful intubation at the first attempt for anaesthetists. Complication rates were comparable for the two specialties.

CONCLUSIONS

Tracheal intubations using RSI in the ED are performed by EPs almost as often as by anaesthetists in this district hospital. Overall success and complication rates are comparable for the two specialties. Laryngoscopy training and the need to achieve intubation at the first (optimum) attempt needs to be emphasised in EP airway training.

Is nasogastric or nasojejunal decompression necessary after gastrectomy? A prospective randomized trial

BACKGROUND

Nasogastric decompression has been routinely used in most major abdominal operations to prevent the consequences of postoperative ileus. The aim of the present study was to assess the necessity for routine prophylactic nasogastric or nasojejunal decompression after gastrectomy.

METHODS

A prospective randomized trial included 84 patients undergoing elective partial or total gastrectomy. The patients were randomized to a group with a postoperative nasogastric or nasojejunal tube (Tube Group, n = 43) or to a group without a tube (No-tube Group, n = 41). Gastrointestinal function, postoperative course, and complications were assessed.

RESULTS

No significant differences in postoperative mortality or morbidity, especially fistula or intra-abdominal sepsis, were observed between the groups. Passage of flatus (P < 0.01) and start of oral intake (P < 0.01) were significantly delayed in the Tube Group. Duration of postoperative perfusion (P = 0.02) and length of hospital stay (P = 0.03) were also significantly longer in the Tube Group. Rates of nausea and vomiting were similar in the two groups. Moderate to severe discomfort caused by the tube was observed in 72% of patients in the Tube Group. Insertion of a nasogastric or nasojejunal tube was necessary in 5 patients in the No-tube Group (12%).

CONCLUSIONS

Routine prophylactic postoperative nasogastric decompression is unnecessary after elective gastrectomy.

Indwelling trans-anastomotic rectal tubes in colorectal surgery: a survey of usage in UK and Ireland

BACKGROUND

The use of rectal tubes in colorectal surgery appears to be a matter of individual choice, with little documented evidence to support their use. This study assesses the current practice of rectal tubes amongst consultant members of the Association of Coloproctology of Great Britain & Ireland (ACPGBI).

METHODS

A piloted questionnaire was sent to practising ACPGBI consultant members listed in the 2003-04 directory. Statistical analysis was performed using SPSS software and Fishers exact test.

RESULTS

Three hundred and thirty-nine replies were received from 579 posted questionnaires (response rate = 58.5%). Rectal tubes were used by 116 (35%) of responding surgeons. Rectal tubes were more commonly used by surgeons with less than 10 years practice as a consultant (P < 0.005). The main indications for tube placement were following ileo-anal or colonic pouch surgery (73%), after any anterior resection (36%) (rectal tubes were reserved for only low anterior resections by 16% of surgeons) and in the rectal stump after total or subtotal colectomy for acute colitis (11%). Twenty-three percent of these practising surgeons would use a rectal tube as an alternative to a diverting stoma, predominantly in selected patients following ileo-anal pouch surgery. A Foley catheter was the commonest type of tube used (70%) and this was usually placed above the anastomosis (80%). Rectal tubes were left in situ for a median of 5 days (range = 1-13 days). Three surgeons (2.6%) reported serious complications including tube perforation of the bowel or anastomosis. Several different mechanisms were suggested for the purpose and functioning of the rectal tube, the commonest being to decompress the rectum and/or pouch.

CONCLUSION

Rectal tube placement is simple and safe and is used by a third of colorectal surgeons in UK and Ireland. Given their simplicity, the efficacy of rectal tubes in reducing local anastomotic complications requires further evaluation within the confines of a randomised controlled trial.

Optimal enteral feeding in children with gastric dysfunction: surgical jejunostomy vs image-guided gastrojejunal tube placement

PURPOSE

Long-term feeding access in children who fail initial gastrostomy is a management quandary. Although image-guided gastrojejunal feeding tube placement (IGJ) is becoming the access of choice in many centers, few studies have compared long-term results with surgical jejunostomy (SJ). The authors compare outcomes with these 2 techniques.

METHOD

A retrospective review of 20 children requiring jejunal feeding access after failing initial gastrostomy was done. Procedures were performed at a tertiary referral center by interventional radiologists (IGJ) or board-certified pediatric surgeons (SJ).

RESULTS

Initially, patients underwent IGJ (n = 14) or SJ (n = 6). Image-guided gastrojejunal feeding tube placement patients required gastrostomy at an average age of 23.8 months, with conversion to IGJ an average of 17.2 months later. SJ patients required gastrostomy at average age of 16.2 months, with conversion to SJ 30.7 months later. Of 14 patients undergoing IGJ, 7 (50%) eventually required SJ because of recurring tube management issues. Thus, 13 patients ultimately had SJ, with 11 (85%) Roux-en-Y jejunostomies. Mean operating time for SJ was 158 minutes, with an average of 5.1 days to initiation of feeds, 11 days to full feeds, and 19.9 days to discharge (range, 3-66 days). Image-guided gastrojejunal feeding tube placement patients averaged 4.6 tube adjustments per year requiring fluoroscopic guidance. Surgical jejunostomy averaged 1.5 tube adjustments per year requiring outpatient hospital visits. Image-guided gastrojejunal feeding tube placement patients averaged 3.9 hospital d/y secondary to feeding tube management issues, whereas SJ patients averaged 1.4 hospital days per year.

CONCLUSION

In this group of children with long-term jejunal feeding access, half of those with IGJ eventually required SJ. Surgical jejunostomy required fewer adjustments and hospitalizations per year. Although initially more invasive than IGJ, SJ may provide more stable feeding access with fewer complications. This represents the first published report comparing long-term outcomes between IGJ and SJ.

Improving processes of hospital care during the last hours of life

BACKGROUND

Known for excellence in care in the last days and hours of life, hospice programs can help individuals have a "good death" and lead to higher family satisfaction with quality of care. Our objective was to evaluate the effectiveness of a multicomponent palliative care intervention based on the best practices of home hospice and designed to improve the quality of care provided for patients dying in an acute care inpatient setting.

METHODS

This study was a before-after intervention trial conducted between 2001 and 2003. Participants included physician, nursing, and ancillary staff on inpatient services of an urban, tertiary care Veterans Affairs medical center. The palliative care intervention included staff education and support to identify patients who were actively dying and implement care plans guided by a comfort care order set template for the last days or hours of life. Data abstracted from computerized medical records of 203 veterans who died during a 6-month period before (n = 108) and after (n = 95) intervention were used to determine the impact of intervention on symptom documentation and 5 process of care indicators.

RESULTS

There was a significant increase in the mean (SD) number of symptoms documented from 1.7 (2.1) to 4.4 (2.7) (P<.001), and the number of care plans increased from 0.4 (0.9) to 2.7 (2.3) (P<.001). Opioid medication availability increased from 57.1% to 83.2% (P<.001), and do-not-resuscitate orders increased from 61.9% to 85.1% (P<.001). There were nonsignificant changes in the proportion of deaths that occurred in intensive care units (P = .17) and in the use of nasogastric tubes (P = .40), and there was a significant increase in the use of restraints (P<.001).

CONCLUSION

Our results indicate that end-of-life care improved after the introduction of the palliative care program.

Incidence of and Risk Factors for Pulmonary Complications after Nonthoracic Surgery

The prediction of postoperative pulmonary complications is an underinvestigated field. We conducted a prospective cohort study (with postoperative pulmonary complications ascertained by an investigator blinded to perioperative variables) to determine the risk factors for pulmonary complications after elective nonthoracic surgery. Of 1,055 consecutive patients attending the Pre-Admission Clinic of a university hospital (mean age 55 years, 50% men, 15% with history of obstructive airways disease), 28 (2.7%) suffered a postoperative pulmonary complication within 7 days of surgery: 13 patients developed respiratory failure requiring ventilatory support, 9 pneumonia, 5 atelectasis requiring bronchoscopic intervention, and 1 pneumothorax requiring intervention. Mean lengths of stay were substantially prolonged for those patients who developed pulmonary complications within 7 days of surgery: 27.9 days versus 4.5 days, p = 0.006. Eight variables were statistically significantly associated with pulmonary complications on bivariate analyses. Multivariate analyses revealed that four were independently associated with increased risk of pulmonary complications: age (odds ratio [OR] 5.9 for age >/= 65 years, p < 0.001), positive cough test (OR 3.8, P = 0.01), perioperative nasogastric tube (OR 7.7, p < 0.001), and duration of anesthesia (OR 3.3 for operations lasting at least 2.5 hours, p = 0.008). Thus, several perioperative factors predict an increased risk for pulmonary complications after elective nonthoracic surgery.

Trends in the use of feeding tubes in North Carolina hospitals

OBJECTIVE

National data describing the placement of feeding tubes demonstrated a rapid increase in use in the early and mid-1990s. In the past several years, substantial concerns have arisen regarding the appropriateness of the procedure in many chronically ill patients. The purpose of this study is to determine whether the use of feeding tubes has continued to increase through the 1990s despite these widely publicized concerns.

DESIGN

Repeated measure cross-sectional study of the North Carolina Discharge Database.

SETTING

Analyses of all nonfederal hospital inpatient admissions in North Carolina.

MEASUREMENTS AND MAIN RESULTS

We examined the absolute numbers and rates of feeding tube placements from 1989 to 2000. The rate of feeding tube placement increased from 59/100,000 persons in 1989 to 94/100,000 persons in 2000, an overall 60% increase with slowing in the rate of increase in the late 1990s. However, when outpatient procedures were included, the increase in tube feeding continued throughout the 11-year period of observation. The increase was due to an increase in utilization within all hospitals over the time period. Utilization did not differ between profit and not for profit hospitals. The relative growth rate of inpatient feeding tube placement did not differ by age group but the absolute increase was greatest in those age 75 years and over.

CONCLUSIONS

Our study demonstrates that the use of feeding tubes has continued to increase through the 1990s. This increase occurred despite ongoing controversy in the medical literature about feeding tube placement in chronically ill patients.

Using rapid-cycle quality improvement methodology to reduce feeding tubes in patients with advanced dementia: before and after study

PROBLEM

Despite lack of evidence that enteral feeding tubes benefit patients with dementia, and often contrary to the wishes of patient and family, patients with dementia who have difficulty swallowing or reduced food intake often receive feeding tubes when hospitalised for an acute illness.

DESIGN

We conducted a retrospective chart review of all patients receiving percutaneous endoscopic gastrostomy or jejunostomy tubes between March and September 2002. QI interventions including a palliative care consulting service and educational programmes were instituted. We conducted a second chart review for all patients receiving feeding tubes between March and September 2003.

SETTING

652 bed urban acute care hospital.

KEY MEASURES FOR IMPROVEMENT

We measured the number of feeding tubes placed in patients with dementia, the number of feeding tubes placed in patients with dementia capable of taking food by mouth, and the number of feeding tubes placed in patients with dementia with an advance directive stating the wish to forgo artificial nutrition and hydration.

STRATEGIES FOR CHANGE

Medical and allied health staff received educational programmes on end of life care and on feeding management of patients with dementia. A palliative care consulting team was established.

EFFECTS OF CHANGE

After the interventions, the number of feeding tubes placed in all patients and in patients with dementia was greatly reduced.

LESSONS LEARNT

Multidisciplinary involvement, including participation by the administration, was essential to effect change in practice. The intensive focus on a particular issue and rapid change led to "culture shift" within the hospital community. The need to establish unified goals of care for each patient was highlighted.

BACKGROUND

A growing body of research over the past decade has questioned the utility of placing feeding tubes (percutaneous endoscopic gastrostomy (PEG) or jejunostomy) in patients with advanced dementia. Studies have found no evidence that feeding tubes in this population prevent aspiration, prolong life, improve overall function, or reduce pressure sores. Additionally, the quality of life of a patient with advanced dementia can be adversely affected when a feeding tube is inserted. The patient may require wrist restraints to prevent pulling on the tube or may develop cellulitis at the gastrostomy site, develop decubitus ulcers, be deprived of the social interaction and pleasure surrounding meals, and require placement in a nursing home. Unfortunately, many doctors are unfamiliar with this literature or face barriers-attitudinal, institutional, or imposed by the healthcare industry-to applying its findings to their practice. Thus feeding tubes are placed in patients who will not benefit from this intervention and whose quality of life in the terminal stage of their illness will be adversely affected. With the expected increase of elderly people with dementia, a great change in doctors' knowledge, attitudes, and practice is necessary to prevent even greater numbers of patients receiving this futile treatment.

Convalescence after colonic resection with fast-track versus conventional care

BACKGROUND

Multi-modal rehabilitation programmes may improve early postoperative body composition, pulmonary function, exercise capacity, and reduce hospital stay. So far, no data are available on convalescence after discharge.

AIM

The objectives were to compare convalescence data (fatigue, sleep, time to resume normal activities, and functional capabilities) and need for nursing care and contact to general practitioner with fast-track multi-modal rehabilitation compared with conventional care after colonic surgery.

METHODS

Non-randomised, prospective controlled study in 30 consecutive patients undergoing fast-track rehabilitation with continuous epidural analgesia, enforced oral nutrition, mobilisation, planned early discharge, and 30 consecutive patients undergoing conventional care. Patients were interviewed preoperatively and 14 and 30 days postoperatively.

RESULTS

Median hospital stay was 2 vs. 8 days in the fast-track vs. conventional care group, respectively (p < 0.01). Fourteen days postoperatively, total and mid-day sleep were increased in the conventional care group when compared with the fast-track group (p < 0.01). Fatigue was increased significantly at 14 days (p < 0.05) and throughout the study period compared with the fast-track group (p < 0.01). Similarly, ability to walking stairs, cooking, house keeping, shopping and walking outdoor was significantly less reduced at 14 days in the fast-track group, who also regained leisure activities earlier (p < 0.05). There was no significant difference between groups at 30 days or between need for nursing care and visits to general practitioners. Readmission for surgery-related events occurred more frequently (5 vs. 1 patient) in the fast-track group.

CONCLUSION

Fast-track rehabilitation with early discharge after colonic surgery results in earlier resumption of normal activities with reduced fatigue and need for sleep postoperatively compared to conventional care, and without increased need for nursing care or visits to general practitioners. However, readmissions may occur more frequently.

Colonic surgery with accelerated rehabilitation or conventional care

BACKGROUND

For patients undergoing colonic surgery, the postoperative hospital stay is usually 6 to 10 days, and the morbidity rate is 15 to 20 percent. Fast-track rehabilitation programs have reduced the hospital stay to 2 to 3 days. The aim of this study was to evaluate the postoperative outcome after colonic resection with conventional care compared with fast-track multimodal rehabilitation.

METHODS

One hundred thirty consecutive patients receiving conventional care (group 1) in one hospital were compared with 130 consecutive patients receiving multimodal, fast-track rehabilitation (group 2) in another hospital. Outcomes were time to first defecation after surgery, postoperative hospital stay, and morbidity during the first postoperative month.

RESULTS

Median age was 74 years (group 1) and 72 years (group 2). American Society of Anesthesiologists (ASA) score was significantly higher in group 2 ( P < 0.05). Defecation occurred on day 4.5 in group 1 and day 2 in group 2 ( P < 0.05). Median hospital stay was 8 days in group 1 and 2 days in group 2 ( P < 0.05). The use of a nasogastric tube was longer in group 1 ( P < 0.05). The overall complication rate (35 patients) was lower in group 2 ( P < 0.05), especially cardiopulmonary complications (5 patients; P < 0.01). Readmission was necessary in 12 percent of cases for group 1 and 20 percent in group 2 ( P > 0.05).

CONCLUSIONS

Time to first defecation, hospital stay, and morbidity may be reduced after colonic resection with fast-track multimodal rehabilitation.

Routine Nasogastric Tubes Are Not Required Following Cystectomy With Urinary Diversion: A Comparative Analysis of 430 Patients

PURPOSE

Postoperative nasogastric tube (NGT) use has been shown to increase postoperative morbidity in patients undergoing nonurological abdominal surgery. We examine the omission of NGTs as a method of decreasing postoperative gastrointestinal complications and hospital stay in patients undergoing cystectomy with urinary diversion.

MATERIALS AND METHODS

Between January 1983 and December 2001, 430 patients underwent cystectomy with urinary diversion at our institution. We retrospectively compared patients who received postoperative NGTs with those who did not with regard to gastrointestinal recovery time, gastrointestinal complications and hospital stay.

RESULTS

After correcting for confounding factors using ANCOVA the time to first bowel sounds, time to first flatus and the duration of hospitalization were shorter in patients not receiving NGTs (p = 0.006, 0.001 and 0.032, respectively). Omitting NGTs did not increase the risk of ileus, bowel obstruction, wound dehiscence, anastomotic leakage or aspiration pneumonia and it did not result in more frequent postoperative NGT placement.

CONCLUSIONS

The results of the current study suggest that gastric decompression with NGTs following cystectomy with urinary diversion may prolong gastrointestinal recovery, which may be a factor leading to increased duration of hospitalization. We propose that postoperative NGTs should not be used routinely in the management of cystectomy cases.

[Complications of enteral nutrition at home. Results of a multicentre trial]

AIM

In spite of the increasing number of home enteral nutrition (HEN) patients, only few articles had reported the frequency of complications related to this treatment. Our multicentric study analyzes the HEN complications in relation to access device and time of treatment.

METHOD

92 HEN patients from 8 hospitals were randomly selected. Patients were distributed in relation to the time of treatment and access device (nasogastric tube and percutaneous or surgical gastrostomies). After an educational program, they were filled in an initial questionnaire and repeated it the days 15 and 30. They received a mean of 1650 Kcal of enteral solution. A total of 2760 HEN prospective days were analyzed.

RESULTS

In prospective study 42% of patients had some complication (112 episodes). The most frequent were gastrointestinal (55%) and mechanical (29%); 0.16 complications of patient-year were registered. The most common complications were: extraction (15%), constipation (13%), vomiting (12%) and diarrhoea (10%). The gastrostomy group had more gastrointestinal complications. In retrospective evaluation, percutaneous gastrostomy group had the lowest ratio of complications and nasogastric tube group required more tube replacements (4 vs 2) and had 1.96 episodes/patient (percutaneous group 1.85 and surgical gastrostomy 3.1 episodes/patient).

CONCLUSION

HEN is safe with low incidence of complications. An adequate educational program is very important and we expect, in the future, to establish an proper National Home Care System.

Animal models of alcoholic liver disease--focus on the intragastric feeding model

The use of animal models has contributed to greater understanding of how alcoholic liver disease (ALD) develops, and of how the severity of liver injury is influenced by factors other than alcohol, such as nutrition, oxygen deprivation (as occurs with sleep apnea or smoking), and gene regulation. This article focuses on the use of one animal model in particular, the intragastric feeding model in rats. This model allows scientists to rigorously control an animal's consumption of both alcohol and dietary nutrients and is providing important information on the mechanisms of injury of alcoholic liver disease.

Therapeutic drug monitoring of theophylline in frail elderly patients: oral compared with nasogastric tube administration

SUMMARY

Treating debilitated elderly patients through nasogastric tube (NGT) can change the pharmacokinetic characteristics of drugs, mainly those that are slow released (SR). The purpose of this study was to compare pharmacokinetic parameters between patients who receive SR theophylline orally and those who receive it through NGT.

PATIENTS AND METHODS

The authors studied elderly patients in the geriatric ward receiving SR theophylline for chronic obstructive lung disease. In 17 patients fed by NGT (group I), theophylline was removed from the capsule and mixed with 10 mL of water. Group II included 15 patients who swallowed the drug orally. Theophylline blood levels were measured, as were peak concentration (C(max) ), time to peak (T(max) ), and area under the serum concentration-time curves (AUC).

RESULTS

The mean daily dose was not statistically different between the two groups: 320 +/- 130 (200-500) mg/d in group I and 360 +/- 85 (200-500) mg/d in group II, given twice daily. All pharmacokinetic measurements were lower in group I as compared with group II: trough theophylline blood levels were 3.78 +/- 3.2 (0.5-10.77) microg/mL versus 8.63 +/- 4.6 (0-15.61) microg/mL ( P= 0.002); C(max) was 6.53 +/- 4.1 (1.3-13.33) microg/mL versus 10.51 +/- 3.30 (4.3-16.28) microg/mL (P = 0.0058), and AUC was 50.04 +/- 38.59 (11-112) microg/h/mL versus 80.37 +/- 28.8 (23-148) microg/h/ml (P = 0.024). CONCLUSIONS Patients receiving the drug through NGT had variability and unexpectedly low blood levels. Therefore, the pharmacokinetic parameters of SR preparations should be evaluated before their administration through NGT.

[Management of dysphagia in the institutionalized elderly patient: current situation]

Elderly patients suffering from dysphagia, institutionalised either in hospital or nursing homes, have been studied. Etiology, characteristics and complications of dysphagia were studied as well as the most frequently used strategies to improve the management of swallowing disorders.

SUBJECTS AND METHODS

A retrospective study of the complications of dysphagia found during the last 4 years in our hospital were conducted in addition to a cross-sectional study of the techniques used to manage dysphagia. A postal questionnaire was sent to all the registered nursing homes in the Valencian Community.

RESULTS

Inhospital patients: 58% of physicians estimated that no less than 20% of patients under their care presented dysphagia. 13% of the total number of hospital diets were specific for swallowing disorders. All the patients suffering from dysphagia used a liquid thickener. Nursing Homes residents: 107 questionnaires were returned. This represents 7057 residents of which 3.6% were suffering from dysphagia. 54% of nursing homes have a specific diet for the management of dysphagia, 51% used nasogastric feeding and 30% consider PEG. The most frequent complications were 75% lung aspirations, 39% dehydration, 32% malnourishment and 31% pneumonia.

CONCLUSIONS

Dysphagia is an important problem in elderly people. In our hospital there is a correct use of a dysphagia diet but it could be more widespread and further measures should be taken. Complications are frequent but are not correctly documented in the medical records. Nursing home residents have frequent and important complications when suffering dysphagia. Interventions towards a better management of dysphagia should be recommended and implemented.

Prophylactic placement of gastrostomy feeding tubes before radiotherapy in patients with head and neck cancer: is it worthwhile?

BACKGROUND

After radiation treatment of head and neck cancer, placement of gastrostomy feeding tubes can be technically difficult. The practice of placing tubes before treatment is probably justified if the tube is used for more than 4 weeks and if complications are infrequent. The aim of this study was to determine the outcome of prophylactically placed gastrostomy tubes in patients with head and neck cancer at our institution from 1995 to 1999.

STUDY

Data collected retrospectively from the patients' medical records included demographics, duration of tube use, and complications associated with placement.

RESULTS

A total of 54 patients (40 men, 14 women) with a mean age of 68.5 years (range, 49-88 years) were studied. Thirty-one patients were treated with both surgery and radiotherapy; 17, with only radiotherapy; and 6, with chemotherapy, radiation, and surgery. The gastrostomy tube was placed before initiation of radiation treatment in 41 patients and after treatment in 13. The method of placement included pull technique (n = 41), introducer technique (n = 10), and surgical (n = 3). Four patients who had a tube placed after treatment required hospitalization for dehydration, whereas no hospitalizations were needed in the prophylactic group. The median duration of tube use was 165 days (range, 0-1,105 days). Only three patients had a complication directly related to placement.

CONCLUSION

Gastrostomy tube placement before treatment is appropriate, given the median number of days required for use and limited complications associated with placement.

Complications associated with enteral nutrition by nasogastric tube in an internal medicine unit

Enteral nutrition through a nasogastric tube is a technique often used with hospitalized patients when they present problems with oral nutrition. Patients receiving enteral nutrition show several kinds of complications such as diarrhoea, vomiting, constipation, lung aspiration, tube dislodgement, tube clogging, hyperglycaemia and electrolytic alterations. We present a prospective and observational study carried out in an Internal Medicine Unit with 64 patients who were fed by a nasogastric tube. From the results it can be seen that older people represented a majority (the average age was 76.2 years), and difficulty in swallowing was the main reason for beginning enteral nutrition. The complications which appeared were: tube dislodgement (48.5%); electrolytic alterations (45.5%); hyperglycaemia (34.5%); diarrhoea (32.8%); constipation (29.7%); vomiting (20.4%); tube clogging (12.5%); and lung aspiration (3.1%). We discuss the possible relationship between the different factors associated with the enteral nutrition procedure and the occurrence of these complications. Finally, some nursing interventions are suggested, such as: checking the gastric residue periodically; attempting to place the tube in the duodenum in unconscious patients; and the use of protective mittens in disturbed patients.

[Incidence of salivary fistulas in relation to timing of oral nutrition after laryngectomy]

BACKGROUND AND OBJECTIVE

A pharyngocutaneous fistula is the most common complication after total laryngectomy. In Germany, a traditional recommendation is to use a nasogastric tube for feeding for 10-14 days postoperatively because many surgeons believe that oral feeding after surgery contributes to fistula development. However, there is no international agreement about when to begin oral feeding after total laryngectomy. Some authors begin oral feeding between the 1st and 4th postoperative day without any nasogastric tube, while others using a nasogastric tube delay oral feedings until 7-14 days after surgery. The aim of the present study was to investigate the relationship between the timing of oral feeding and the development of fistulas after total laryngectomy.

PATIENTS/METHODS

In a prospective trial with 42 consecutive patients who underwent laryngectomy, oral feeding was started on different postoperative days between the 1st and the 10th. Most patients were selected randomly for the different postoperative days. Furthermore, other potential risk factors predisposing to fistula formation were analyzed retrospectively.

RESULTS

Five fistulas occurred in the total group (12%). Early postoperative oral feeding does not increase the incidence of fistulas. The fistula rate was only 9% in patients fed orally in the 1st postoperative week. The analysis of further risk factors for fistula formation showed only a significant correlation between type of resection and fistula occurrence (extended laryngectomy with partial pharyngectomy vs standard laryngectomy; p = 0.018).

CONCLUSIONS

Our results indicate that early oral feeding in the 1st postoperative week does not influence fistula formation after laryngectomy.

Tonsillar application of formalin-killed cells of Streptococcus sobrinus reduces experimental dental caries in rabbits

Living Streptococcus sobrinus cells were orally inoculated into nonimmune rabbits and rabbits immunized with formalin-killed cells of S. sobrinus through tonsillar application to examine the anticaries potential of this method of immunization. The living S. sobrinus cell numbers and the caries areas in the rabbits immunized by tonsillar application decreased to a level one-fifth of that in nonimmune rabbits.

[Nasogastric tubes after elective abdominal surgery is not justified]

There is no need for systematic nasogastric tube after elective abdominal and digestive surgery. Expected benefits are comfort for the patient, reduction of pulmonary morbidity, and rapid oral feeding. Only 5% of the patients will need a subsequent placement of nasogastric tube, due to vomiting and abdominal distention, with no adverse effects.

"Ideal" length of stay after colectomy: whose ideal?

PURPOSE

In response to external pressure to achieve an idealized length of stay after colon resection, a study was designed to define perioperative factors that significantly impact average length of stay (ALOS).

METHODS

We retrospectively reviewed the records of 226 patients undergoing open colon resection from 1988 to 1995 to determine the effects of age, type of procedure, nature of the procedure (elective vs. emergency), and postoperative course on ALOS. Statistics were calculated by Student's t-test, chi-squared analysis, and analysis of variance.

RESULTS

Average length of stay was 10 (range, 4-34) days, with a significant trend toward lower ALOS in recent years; ALOS in 1988 averaged 11 days, whereas in 1994, ALOS averaged 9 days (r2 = 0.118; P < 0.001). Patients younger than 65 years of age had an ALOS of 9 days vs. 11 days in patients older than 65 years (P = 0.0024). Patients with anastomoses on the right and left side had similar ALOS (8.5 vs. 9.1 days), whereas creation of a stoma was associated with a significantly higher ALOS (12.1 days; P < 0.00001). The need for postoperative nasogastric intubation (14.9 vs. 9.3 days) and the performance of emergency operations (12.2 vs. 6.5 days) were also associated with a significantly higher ALOS (P < 0.00001).

CONCLUSIONS

Caution must be exercised in accepting rigid criteria for length of stay for patients undergoing colorectal resections, as uncontrollable clinical variables are involved in defining the "ideal" patient.

[Is a clinical positional control for nasogastric tubes good enough? A prospective study of 43 patients]

OBJECTIVE

Nasoenteric tubes are usually introduced blindly by nursing staff, i.e. without visual or radiological control. A prospective study was undertaken to determine how often such blind procedure results in potentially dangerous tube placement and how often such faulty positioning remains undetected in a standardised clinical check.

PATIENTS AND METHODS

43 patients (23 men, 20 women; age 24-90 years) requiring the introduction by nursing staff of a nasoenteric tube were studied, 12 in an intensive care unit (seven intubated) and 31 in an ordinary ward. At most 24 hours after the customary check of the tube's position by the nursing staff (air injection with epigastric auscultation), specially experienced medical and nursing personnel determined and recorded the tube's placement in a standardised manner. Subsequent radiological examination documented the position.

RESULTS

All 43 tubes lay in the gastrointestinal tract. Only one tube was in a potentially dangerous position in the lower end of the oesophagus, as had already been diagnosed by the examiners. Of four other tubes which were not optimally placed (three in the region of the cardia, one in the duodenum) three were found to be "not correctly placed" by the clinical check, and one was detected only radiologically.

CONCLUSIONS

Clinical control of a nasoenteric tube's position suffices in most instances. Checking the position further by an experienced person adds to safety. The study's findings suggest that radiological control can be safely limited to cases in which there was a problem in positioning the tube or the clinical control was unclear.

Confirmation of cecal intubation during colonoscopy

PURPOSE

Establishing intubation of the cecum can be a laborious, frustrating, and sometimes erroneous endeavor. Following confirmed colonoscopic intubation of the cecum, the presence of three anatomic landmarks (alone and in combination) were evaluated to precisely define their reliability.

METHODS

Between February 1991 and January 1992, 771 of 904 consecutive colonoscopic examinations were completed to the cecum as confirmed by fluoroscopy.

RESULTS

All three cecal landmarks studied (ileocecal valve, appendiceal orifice, and transillumination) were present in 64 percent of patients, and two landmarks were seen in 32 percent (96 percent of patients had multiple landmarks). The ileocecal valve was the most reliable cecal landmark (98 percent), followed by the appendiceal orifice (87 percent) and transillumination through the abdominal wall (75 percent).

CONCLUSIONS

The ileocecal valve is the most reliable cecal landmark and is invariably visualized, even when all other cecal landmarks are obscure. Although other cecal landmarks are usually identifiable, they are most valuable when found in association with the ileocecal valve.

Risk factors and clinical relevance of nosocomial maxillary sinusitis in the critically ill

The incidence of infectious maxillary sinusitis (IMS) and its clinical relevance was prospectively studied in 162 consecutive critically ill patients who were mechanically ventilated for a period longer than 7 d. All had a paranasal computed tomographic (CT) scan within 48 h of admission and were divided into three groups according to the radiologic aspect of their maxillary sinuses: Group 1 = normal maxillary sinuses (n = 40), Group 2 = maxillary mucosal thickening (n = 26), Group 3 = radiologic maxillary sinusitis (RMS) defined as the presence of an air fluid level and/or opacification of maxillary sinuses (n = 96). Group 1 patients were randomized between nasal and oral endotracheal intubation with a gastric intubation performed via the same route and had a second paranasal CT scan 7 d later. Endotracheal and gastric tubes were left in their original position in Group 2 patients and a second paranasal CT scan was performed 7 d later. All patients of Group 3 underwent a transnasal puncture for bacteriologic analysis of maxillary sinus content. Forty-five spontaneously breathing patients served as a control group. In all patients with RMS, the occurrence of bronchopneumonia (BPN) was prospectively assessed for 7 d following the initial CT scan. Upon inclusion, only 25% of the patients had normal maxillary sinuses whereas all patients in the control group had normal paranasal CT scans. After 7 d, 46% of Group 2 patients had evidence of RMS. Risk factors for RMS were nasal placement and duration of endotracheal and gastric intubation.(ABSTRACT TRUNCATED AT 250 WORDS)

Equivalence of litmus paper and intragastric pH probes for intragastric pH monitoring in the intensive care unit

OBJECTIVE

To compare the accuracy of litmus paper-determined gastric pH to a nasogastric graphite antimony pH probe.

DESIGN

A prospective clinical trial of gastric pH determination in patients enrolled in a study of histamine-2-receptor (H2) antagonists.

SETTING

The medical intensive care unit (ICU) of a 450-bed county hospital.

PATIENTS

Critically ill ICU patients requiring stress ulcer prophylaxis.

INTERVENTIONS

Using a crossover design, the patients were randomized to initially receive an H2 antagonist by continuous infusion or intravenous bolus, and subsequently were crossed over to the other limb of the study.

MEASUREMENTS AND MAIN RESULTS

Gastric pH was determined using pH-sensitive litmus paper at the initiation of each limb of the study and at 1, 2, 4, and 8 hrs after the initiation of H2 receptor antagonist therapy. In addition, gastric pH was continuously determined over the same time period utilizing a graphite antimony pH probe. Gastric pH measurements determined with litmus paper and intragastric pH probes demonstrated an excellent correlation (r2 = .93, p < .001). McNemar's test of correlated proportions could not demonstrate a significant difference between the two monitoring methods (chi-square = 0.5, p > .47), and the kappa statistic (0.95, p < .001) demonstrated excellent concordance. Bias measurement was 0.01 (95% confidence interval = -0.155 to 0.176).

CONCLUSIONS

Measurement of intragastric pH, using pH-sensitive litmus paper, is both sensitive and specific when utilizing a graphite antimony nasogastric pH probe as a reference standard. Litmus paper-determined gastric pH testing is both easy to perform and inexpensive. Therefore, based on the current data, we believe this technique (i.e., litmus paper determined gastric pH testing) to be the method of choice for determination of intragastric pH in patients at risk for stress gastric ulcers in the medical ICU.

[Nasogastric tubes in geriatric patients]

The nasogastric tube (NGT) not only provides nutritional support, but is also an effective diagnostic and therapeutic aid. We present the profile of the geriatric patient who needs the NGT, the reasons for its use, and mortality in these patients. 25 women (aged 83.9 +/- 5.5) and 25 men (aged 79 +/- 7.7) required the NGT, 15 of them only temporarily (TNGT) and 35 permanently (PNGT). The percentage of those with chronic neurologic disorders and/or incontinence (fecal or urinary), was highest in the PNGT group, as was the number of drugs used per patient (4.2 +/- 1.8 vs. 2.9 +/- 1.4). Laboratory studies showed no differences between the groups. PNGT was used in those whose conditions were chronic and progressive (inability to swallow or not sufficiently alert for oral nutrition). TNGT was used commonly as a diagnostic or therapeutic aid. During the study 20 patients died (40%), all in the PNGT group. Pneumonia was the main cause of death (18%), followed by decubitus ulcer (14%) and urinary tract infections (8%).

Advanced trauma life support program increases emergency room application of trauma resuscitative procedures in a developing country

Over a 9-year period (July 1981-December 1985--pre-ATLS period; January 1986-June 1990--post-ATLS period), the hospital charts of 813 trauma patients with ISS > or = 16 were reviewed (n = 413, pre-ATLS and n = 400, post-ATLS) in order to assess the impact of the ATLS program. The frequency of endotracheal intubation (ET), nasogastric tube insertion (NG), intravenous access (i.v.), Foley catheterization of the bladder (Foley) and chest tube insertion (CT) were compared by Pearson Chi-square analysis. Overall, pre-ATLS vs. post-ATLS frequencies (%) were 83.5 vs. 65.3 for ET, 97.3 vs. 98.0 for i.v., 74.6 vs. 96.3 for Foley, 68.3 vs. 91.3 for NG, and 18.4 vs. 47.0 for CT. In the emergency room these frequencies (%) were 26.1 vs. 36.4 for ET, 98.8 vs. 98.7 for i.v., 11.0 vs. 97.1 for Foley, 3.2 vs. 95.9 for NG, and 3.9 vs. 95.2 for CT. The differences in the application of these life saving procedures between the pre-ATLS and post-ATLS periods were statistically significant (p < 0.05) except i.v. access, which showed no difference between the pre-ATLS and post-ATLS groups. Of the patients with severe chest injuries (AIS > or = 3) 87.7% had chest tubes post ATLS (94.4% in ER) compared with 48.1% pre ATLS (3.2% in ER). These differences were associated with significant improvement in trauma patient outcome post ATLS. We conclude that the frequency of lifesaving interventions, particularly in the ER, was increased post ATLS.(ABSTRACT TRUNCATED AT 250 WORDS)

Respiratory complications in critically ill medical patients with acute upper gastrointestinal bleeding

STUDY OBJECTIVE

To determine types of respiratory complications encountered in critically ill patients with serious acute upper gastrointestinal (GI) bleeding, and to identify associated risk factors.

DESIGN

Retrospective chart review.

SETTING

A university hospital medical ICU.

PATIENTS AND METHODS

We reviewed medical records of 86 patients admitted to the medical ICU over a 2 1/2-yr period of time, for 107 consecutive episodes of serious acute upper GI bleeding. Clinical features of patients who developed respiratory complications of pneumonia, witnessed aspiration of gastric contents, or who required intubation and mechanical ventilation for other reasons were compared with those features of patients without respiratory complications.

MAIN RESULTS

Respiratory complications occurred during 23 (22%) serious upper GI bleeding episodes (mean transfusion requirement, 7 units of packed RBCs). Twelve patients developed pneumonia and all had evidence of advanced liver disease. Five patients were observed to aspirate gastric contents and six patients require intubation and mechanical ventilation for reasons other than pneumonia or aspiration. Esophageal sites of bleeding (esophagitis, esophageal ulcers and esophageal varices), advanced liver disease, age greater than 70 yrs, and an Acute Physiology and Chronic Health Evaluation (APACHE) II score greater than 13 appeared to be risk factors. Mortality rate was increased in patients with respiratory complications: 70% of patients with respiratory complications died, compared with 4% of those patients without such problems (p less than .001).

CONCLUSIONS

Respiratory complications are common in critically ill medical patients with serious acute upper GI bleeding, and are associated with a poor outcome. Risk factors include advanced liver disease, esophageal site of bleeding, age greater than 70 yrs, and higher APACHE II score.
