Abstract
BACKGROUND The presence of nucleated red blood cells (NRBCs) has been identified as a poor prognostic indicator. We investigated the relationship of NRBC trends in patients with and without trauma. METHODS We retrospectively reviewed surgical intensive care unit admissions over 4 years, categorizing trauma and nontrauma patients and subdividing them into 3 groups: group A, all-zero NRBC; group B, positive NRBC value returning to zero; and group C, positive NRBC value that did not return to zero. We analyzed all groups for outcomes of length of stay and mortality. RESULTS Group A was the largest and had the shortest length of stay and least mortality. Group C had the highest mortality rate. No statistical difference was observed with mortality. CONCLUSIONS Any positive NRBC was associated with poor outcome, and increasing NRBC was associated with increasing mortality. Trends in NRBC values showed that returning to zero was protective.

Abstract
BACKGROUND Laparoscopic colectomy has been associated with fewer postoperative complications than open colectomy. However, it is unclear whether this is true for the most severe complications typically requiring treatment in an intensive care unit (ICU). The authors hypothesized that laparoscopic colectomy patients have fewer of the most severe complications even after adjustment for comorbidity risk. METHODS Using the National Surgical Quality Improvement Program (NSQIP) public use files for 2005-2008, the authors identified all laparoscopic (n = 12,455) and open (n = 33,190) colectomies by current procedural terminology (CPT) code. Using the Clavien classification for postoperative complications, they identified NSQIP data points most consistent with Clavien grade 4 complications requiring ICU care (postoperative septic shock, postoperative dialysis, pulmonary embolism, myocardial infarction, cardiac arrest, prolonged ventilatory requirements, need for reintubation) or grade 5 complication (mortality). Statistical analysis was performed using SPSS software. Odds ratios were calculated to compare laparoscopic and open colectomy regarding the probability of having any Clavien class 4 or 5 complication. Logistic regression was performed to account for the effect of preoperative conditions (American Society of Anesthesiology class, wound class, gender, preoperative functional status, preoperative albumin level, azotemia, thrombocytopenia, emergency case, and age >70 years) on complications. RESULTS The univariate odds ratio showed a 2.27- to 5.52-fold greater likelihood that a patient would have a complication requiring ICU admission if open rather than laparoscopic surgery was performed (p < 0.001). Multivariate logistic regression accounting for preoperative comorbidities that might affect outcome showed persistence of an increase in complications, with an odds ratio range of 1.63 to 2.21. CONCLUSION Evaluation of the NSQIP database demonstrated that laparoscopic colectomy confers an independent protective effect on the frequency of ICU-level (Clavien grade 4) complications and mortality. The protective effect remained evident after correction for preoperative conditions that might have affected outcome.

Abstract
The need for good quality and safety research has never been more imperative, but even as we encourage and promote such work, we seem to suppress it through institutional bias and inertia. Indeed the culture of health care seems to have a love-hate relationship with quality-improvement work as a whole. In this commentary we explore some of the implications of the application of pure science standards at the sharp end of clinical practice, where the down-and-dirty street-level improvement work happens.

Abstract
UNLABELLED While clinicians' management of severe sepsis and septic shock has been positively influenced by a number of clinical research studies in the last decade, challenges remain regarding early hemodynamic optimization as envisioned in the Surviving Sepsis Campaign's (SSC) resuscitation bundle (RB). We examined the impact of a hospital-wide continuous quality improvement (CQI) initiative on patients presenting with severe sepsis and septic shock, and the impact of the sepsis RB on patient outcomes when completed beyond the 6-hour recommendation period. The study was an 18-month, prospective cohort study enrolling patients who met the definition of severe sepsis or septic shock. Compliance with the hemodynamic components of the sepsis RB was defined as achieving goal mean arterial pressure (MAP) ≥ 65 mm Hg, central venous pressure (CVP) ≥ 8 mm Hg, and central venous oxygen saturation (ScvO₂) ≥ 70%. Compliance was assessed at 6 hours and 18 hours after diagnosis of severe sepsis or septic shock. In all, 498 patients with severe sepsis and/or septic shock were evaluated to determine the upper limit of the range of hours that compliance with the RB would still improve outcomes. Using 18 hours as a marker, Compliers at 18 hrs and Non-Compliers at 18 hrs were compared. There were 202 patients who had the RB completed in less than or equal to 18 hours. There were 296 patients who did not complete the RB at 18 hours. The Compliers at 18 hrs had a significant 10.2% lower hospital mortality 37.1% (22% relative reduction) compared to the Non-Compliers at 18 hrs hospital mortality of 47.3% (P < .03). When the two groups were adjusted for differences in baseline illness severity, the Compliers at 18 hrs had a greater reduction in predicted mortality of 26.8% versus 9.4%, P < 0.01. CONCLUSIONS Initiating the sepsis RB for patients with severe sepsis and/or septic shock decreased mortality. A CQI initiative that monitored the implementation in real-time allowed for improvement in compliance and efficacy of the bundle on outcomes. Multiple studies have shown that compliance to the RB within 6 hours lowers hospital mortality. This study uniquely shows that when bundle completion is extended to 18 hours, the mortality reduction remains significant.

Abstract
BACKGROUND In 2000, we implemented an evidence-based guideline in the surgical intensive care unit (SICU) using a transfusion threshold of hemoglobin <8 g/dL. We hypothesized that continual education on the transfusion protocol would decrease transfusions. METHODS We analyzed 2-month samples of admissions in even-numbered years from 1998 to 2006. Any infusion of packed red blood cells (PRBCs) was included. RESULTS We analyzed data from 2,138 patients resulting in 5,130 transfusions. Thirty-six patients received >20 U of blood. The only difference between groups occurred in 2006 when renal failure increased. Transfusions decreased from 3.2 +/- 0.34 (SE) to 1.7 +/- 0.2. The number of patients who received blood also decreased. Mortality and length of stay (LOS) were not different among the groups. Every unit of blood transfused increased the mortality risk by 14%. CONCLUSIONS Implementation of an evidence-based transfusion guideline reduced the number of infused units and patients transfused without an increase in mortality.

Abstract
BACKGROUND Hyperbilirubinemia in intensive care unit (ICU) patients is common. We hypothesized that hyperbilirubinemia in the surgical ICU predisposes patients to infection. METHODS Patients with bilirubin < or = 3 mg/dL were compared to patients with bilirubin > 3 mg/dL. We then compared the low bilirubin patients to high bilirubin patients who developed infection after their hyperbilirubinemia. RESULTS There were 1,620 infections in 5,712 patients with low bilirubin (28%), compared with 284 in 409 patients in the high bilirubin group (69%, P < .001). After removing the patients in whom hyperbilirubinemia developed after infection, we found infection in 156 of 281 remaining patients (56%, P < .001). This group had a 3-fold increased risk of infection compared with low bilirubin (odds ratio [OR] 3.17, 95% confidence interval [CI] 2.48-4.03, P < .001). CONCLUSIONS There is an increased susceptibility to infection among jaundiced surgical ICU (SICU) patients that persists even when sepsis-related hyperbilirubinemia patients are excluded.

Abstract
The negative impact of mild to moderate renal dysfunction on patient outcome is often under-estimated. Any amount of renal dysfunction is deleterious in the surgical intensive care unit (SICU). We evaluated all surgery patients admitted to our SICU. We identified two groups of patients: no renal failure and acute renal failure. A total of 5152 patients were included in this study. There were 1259 patients in the acute renal failure group. The average number of ventilator days increased by 2.2 for every increase of creatinine by 1.0. Patients who required dialysis stayed an average of 11 days longer than patients who did not have any renal failure. For every increase of creatinine by 1.0, average cost increased by $23,048. Only 7 per cent of the patients with acute renal failure required dialysis (n = 85). The odds ratio for mortality compared with those patients without renal failure was 7.06 (confidence interval, 3.91-12.76) regardless of the definition of renal failure. This study demonstrates that even mild to moderate renal failure increases mortality. Moreover, we demonstrated that even a mild decline in renal function increases length of stay, ventilator days, and cost in patients in the SICU. Aggressive vigilance in the prevention of any loss of renal function is warranted in the SICU.

Abstract
BACKGROUND Acute renal failure (ARF) is a devastating complication in critically ill patients. There is a paucity of data that describes the impact of ARF on the outcome of trauma patients admitted to the intensive care unit. METHODS We studied trauma patients admitted to the surgical intensive care unit to determine the effect of increases in serum creatinine on the number of ventilator days, length of stay, mortality, and cost. We used the administrative database of the hospital and the trauma registry. Renal failure (RF) was defined as one or more of the following: creatinine >1.5 mg/dL, increase in creatinine of >50%, or increase of creatinine by 0.5 mg/dL. RESULTS We obtained data on 1,033 patients. Two hundred and forty-six (23.8%) patients met at least one criterion for RF. Only 25 of these patients had one or more episodes of renal replacement therapy. The RF group had mortality of 24.4% compared with 2.3% in the no renal failure group (p < 0.0001). For each 1 mg/dL increase from the initial creatinine, length of stay increased by 2.21 days, ventilator days increased by 1.09 days, and the mortality risk increased by 1.83 times (CI, 1.47-2.29; p < 0.0001). For any diagnosis of renal dysfunction, the average cost increase was $3,088.00 and increased mortality risk was 7.19 times (CI, 4.11-12.58). CONCLUSION Vigilance in preventing creatinine increases and ameliorating or removing potential causes should occur as soon as creatinine begins to rise to avoid worsening renal function, to reduce cost, and to improve patient outcome.

Abstract
Abstract
A retrospective review of 229 patients with a final diagnosis of small-bowel obstruction was undertaken to evaluate the role of contrast radiography in the management of their conditions. In 84 patients (37%) the clinical findings and plain abdominal roentgenograms were sufficient for diagnosis and subsequent management. Of the remaining 145 patients with equivocal findings, 27% had an upper gastrointestinal series, 29% a barium enema, and 44% had both. Useful information (complete obstruction, unobstructed passage of contrast, or diagnosis other than adhesional obstruction) was obtained from 86% of the radiographic studies. Three patients had negative contrast studies yet eventually underwent adhesiolysis (enterolysis) and were classified as false-negative. Two patients had evidence of high-grade obstruction yet had nonoperative resolution and were classified as false-positive. The mortality in the contrast group (7%) was not statistically different than that in the no-contrast group (7%). Contrast radiography is a safe and effective means of increasing diagnostic accuracy in patients with presumed small-bowel obstruction. (SURGERY 1989; 106: 496-501.).

Abstract
OBJECTIVE The mixed venous-arterial (v-a) pCO(2) difference has been shown to be inversely correlated with the cardiac index (CI). A central venous pCO(2), which is easier to obtain, may provide similar information. The purpose of this study was to examine the correlation between the central venous-arterial pCO(2) difference and CI. DESIGN Prospective, cohort study. SETTING Intensive care unit of an urban tertiary care hospital. PATIENTS AND PARTICIPANTS Eighty-three consecutive intensive care unit patients. MEASUREMENTS Simultaneous blood gases from the arterial, pulmonary artery (PA), and central venous (CV) catheters were obtained. At the same time point, cardiac indices were measured by the thermodilution technique (an average of three measurements). The cardiac indices obtained by the venous-arterial differences were compared with those determined by thermodilution. RESULTS The correlation (R(2)) between the mixed venous-arterial pCO(2) difference and cardiac index was 0.903 (p <0.0001), and the correlation between the central venous-arterial pCO(2) difference and cardiac index was 0.892 (p <0.0001). The regression equations for these relationships were natural log (CI)=1.837-0.159 (v-a) CO(2) for the PA and natural log (CI)=1.787-0.151 (v-a) CO(2) for the CV (p <0.0001 for both). The root-mean-squared error for the PA and CV regression equations were 0.095 and 0.101, respectively. CONCLUSION Venous-arterial pCO(2) differences obtained from both the PA and CV circulations inversely correlate with the cardiac index. Substitution of a central for a mixed venous-arterial pCO(2) difference provides an accurate alternative method for calculation of cardiac output.

Abstract
BACKGROUND: Critically ill cardiothoracic patients are prone to hyperglycemia and an increased risk of surgical site infections postoperatively. Aggressive insulin treatment is required to achieve tight glycemic control (TGC) and improve outcomes. OBJECTIVE: To examine and report on the performance of an insulin infusion protocol to maintain TGC, defined as a blood glucose level of 80–150 mg/dL, in critically ill cardiothoracic surgical patients. METHODS: A nurse-driven insulin infusion protocol was developed and initiated in postoperative cardiothoracic surgical intensive care patients with or without diabetes. In this before—after cohort study, 2 periods of measurement were performed: a 6–month baseline period prior to the initiation of the insulin infusion protocol (control group, n = 174) followed by a 6–month intervention period in which the protocol was used (TGC group, n = 168). RESULTS: Findings showed percent and time of blood glucose measurements within the TGC range (control 47% vs TGC 61%; p = 0.001), AUC of glucose exposure >150 mg/dL versus time for the first 24 hours of the insulin infusion (control 28.4 vs TGC 14.8; p < 0.001), median time to blood glucose <150 mg/dL (control 9.4 h vs TGC 2.1 h; p < 0.001), and percent blood glucose <65 mg/dL as a marker for hypoglycemia (control 9.8% vs TGC 16.7%; NS). CONCLUSIONS: An insulin infusion protocol designed to achieve a goal blood glucose range of 80–150 mg/dL efficiently and significantly improved TGC in critically ill postoperative cardiothoracic surgery patients without significantly increasing the incidence of hypoglycemia.

Abstract
OBJECTIVE Critical care medicine trainees and faculty must acquire and maintain the skills necessary to provide state-of-the art clinical care to critically ill patients, to improve patient outcomes, optimize intensive care unit utilization, and continue to advance the theory and practice of critical care medicine. This should be accomplished in an environment dedicated to compassionate and ethical care. PARTICIPANTS A multidisciplinary panel of professionals with expertise in critical care education and the practice of critical care medicine under the direction of the American College of Critical Care Medicine. SCOPE Physician education in critical care medicine in the United States should encompass all disciplines that provide care in the intensive care unit and all levels of training: from medical students through all levels of postgraduate training and continuing medical education for all providers of clinical critical care. The scope of this guideline includes physician education in the United States from residency through ongoing practice after subspecialization. DATA SOURCES AND SYNTHESIS Relevant literature was accessed via a systematic Medline search as well as by requesting references from all panel members. Subsequently, the bibliographies of obtained literature were reviewed for additional references. In addition, a search of organization-based published material was conducted via the Internet. This included but was not limited to material published by the American College of Critical Care Medicine, Accreditation Council for Graduate Medical Education, Accreditation Council for Continuing Medical Education, and other primary and specialty organizations. Collaboratively and iteratively, the task force met, by conference call and in person, to construct the tenets and ultimately the substance of this guideline. CONCLUSIONS Guidelines for the continuum of education in critical care medicine from residency through specialty training and ongoing throughout practice will facilitate standardization of physician education in critical care medicine.

Abstract
OBJECTIVE The development of practice guidelines for the conduct of intra- and interhospital transport of the critically ill patient. DATA SOURCE Expert opinion and a search of Index Medicus from January 1986 through October 2001 provided the basis for these guidelines. A task force of experts in the field of patient transport provided personal experience and expert opinion. STUDY SELECTION AND DATA EXTRACTION Several prospective and clinical outcome studies were found. However, much of the published data comes from retrospective reviews and anecdotal reports. Experience and consensus opinion form the basis of much of these guidelines. RESULTS OF DATA SYNTHESIS Each hospital should have a formalized plan for intra- and interhospital transport that addresses a) pretransport coordination and communication; b) transport personnel; c) transport equipment; d) monitoring during transport; and e) documentation. The transport plan should be developed by a multidisciplinary team and should be evaluated and refined regularly using a standard quality improvement process. CONCLUSION The transport of critically ill patients carries inherent risks. These guidelines promote measures to ensure safe patient transport. Although both intra- and interhospital transport must comply with regulations, we believe that patient safety is enhanced during transport by establishing an organized, efficient process supported by appropriate equipment and personnel.

Abstract
Our objective was to develop criteria to identify patients with traumatic brain injury (TBI) who require a tracheostomy (TR). From January 1994 to May 2000 all TBI patients requiring intubation on presentation and who survived >7 days were identified from our trauma registry. Demographics, Glasgow Coma Score (GCS), Injury Severity Score (ISS), and ventilator days, ICU days, hospital days, need for TR, and development of pneumonia were statistically analyzed. Of 246 patients with TBI 211 without TR and 35 with TR were identified (mean time to TR 13.3+/-7.0 days). Logistic regression analysis identified presenting GCS < or =8, ISS > or =25, and ventilator days >7 as significant predictors for TR. Applying these three predictors to our population identified 48 patients (21 with TR, 18 without TR, and nine who died on the ventilator without TR) with a sensitivity of 60 per cent, a specificity of 87 per cent, a positive predictive value of 44 per cent, and a negative predictive value of 93 per cent. Patients with TR had lower presenting GCS and higher ventilator, ICU, and hospital days (P < 0.05). Pneumonia rates were similar. Time to neurologic recovery (GCS > or =9) was longer for the TR patients as compared with the patients without TR. We conclude that patients with TBI presenting with a GCS < or =8, an ISS > or =25, and ventilator days >7 are more likely to require TR. Performing TR late did not reduce pneumonia rates or ventilator, ICU, or hospital days. By identifying the at-risk population early TR could be performed in an attempt to decrease morbidity and length of stay.

Abstract
Primary venorrhaphy for traumatic inferior vena cava (IVC) injury has been criticized because of the potential for stenosis, thrombosis, and embolism. A retrospective study was performed to evaluate the morbidity and outcome of this method. Thirty-eight patients at our institution had traumatic injuries to the IVC between 1994 and 1999. Thirty (79%) were from firearms, five (13%) from stab wounds, and three (8%) from blunt trauma. Six patients died in the emergency department. The remaining 32 patients underwent exploratory celiotomy with 23 survivors and nine intraoperative deaths for a mortality rate of 28 per cent (nine of 32). Vascular control was achieved by manual compression in 44 per cent and by local clamping directly above and below the injury in 38 per cent. All repairs were by primary venorrhaphy, and no patient was treated with patch angioplasty or venous reconstruction. Three patients had caval ligation. Follow-up IVC imaging in 11 patients revealed that the IVC was patent in eight, narrowed in two, and thrombosed below the renal veins in one. One patient developed a pulmonary embolus. The vast majority of traumatic injuries to the IVC can be managed by direct compression or local clamping and primary venorrhaphy. Direct repairs are associated with a low thrombosis and embolic complication rate.

Abstract
STUDY OBJECTIVES To examine the incidence and response to treatment of adrenal insufficiency (AI) in high-risk postoperative patients. DESIGN Prospective observational case series. SETTING Large urban tertiary-care surgical ICU (SICU). PARTICIPANTS Adults > 55 years of age who required vasopressor therapy after adequate volume resuscitation in the immediate postoperative period. INTERVENTIONS Each patient underwent a cosyntropin (ACTH) stimulation test; at the discretion of the clinical team, some patients were empirically given hydrocortisone (100 mg IV q8h for three doses) before serum cortisol values became available. MEASUREMENTS Adrenal dysfunction (AD), defined as serum cortisol < 20 microg/dL at all time points, with Delta cortisol (60 min post-ACTH minus baseline) of < or = 9 microg/dL; functional hypoadrenalism (FH), defined as serum cortisol < 30 microg/dL at all time points or Delta cortisol (60 min post-ACTH minus baseline) < or = 9 microg/dL; and AI, as the presence of either AD or FH. RESULTS One hundred four patients were enrolled with a mean age (SD) of 65.2 +/- 16.9 years. AI (AD plus FH) was found in 34 of 104 patients (32.7%): AD was found in 9 patients (8.7%), FH in 25 patients (24%), and normal adrenal function in 70 patients (67.3%). The absolute eosinophil count was significantly higher in the combined AD and FH groups compared with the group with normal adrenal function (p < 0.05). Forty-six of 104 patients (44.2%) received hydrocortisone; 29 (63%) could be weaned from treatment with vasopressors within 24 h. This beneficial effect of hydrocortisone reached statistical significance in the FH group when compared with untreated patients (p < 0.031); a similar trend was seen in the AD group (p = 0.083). Mortality was also lower in the hydrocortisone-treated AI patients (5 of 23 [21%] vs 5 of 11 [45%] in those not receiving hydrocortisone; p < 0.01). CONCLUSION There is a high incidence of AI among SICU patients > 55 years of age with postoperative hypotension requiring vasopressors. There is also a significant association between hydrocortisone replacement therapy, resolution of vasopressor requirements, and improved survival.

Abstract
BACKGROUND Although sternal fractures after blunt chest trauma are markers for significant impact, the fracture itself is generally not associated with any specific wound complications. Mediastinal abscess and sternal osteomyelitis rarely occur after blunt trauma or cardiopulmonary resuscitation. Management of such complications is difficult, and requires a spectrum of operative procedures that range from simple closure to muscle flap reconstruction. METHODS The trauma registry of a Level I trauma center was used to identify patients suffering a sternal fracture between January of 1994 and August of 1997. Records were reviewed for the mechanism of injury, length of hospital stay, and posttraumatic mediastinal abscess. RESULTS Twenty-six patients were identified with sternal fracture. No clinically significant cardiac or aortic complications were noted. Three patients, all with a history of intravenous drug abuse and requiring central venous access in the emergency room, developed methicillin resistant Staphylococcus aureus mediastinitis. Sternal re-wiring and placement of an irrigation system successfully treated all three patients. CONCLUSION Posttraumatic mediastinal abscess is an uncommon complication of blunt trauma in general and sternal fracture in particular. It can be recognized by the development of sternal instability. Risk factors include the presence of hematoma, intravenous drug abuse, and source of staphylococcal infection. Treatment with early debridement and irrigation can avoid the need for muscle flap closure.

Abstract
OBJECTIVE To establish the validity and reliability of a new sedation scale, the Motor Activity Assessment Scale (MAAS). DESIGN Prospective, psychometric evaluation. SETTING Sixteen-bed surgical intensive care unit (SICU) of a 937-bed tertiary care, university-affiliated teaching hospital. PATIENTS Twenty-five randomly selected, adult, mechanically ventilated, nonneurosurgical patients who were admitted to the SICU > or = 12 hrs after surgery and were not receiving neuromuscular blockers. INTERVENTION Four hundred assessments (eight per patient) were completed consecutively but independently, in pairs, at standardized times (both day and night) by two nurses who were preselected for each assessment from a pool of 32 pretrained SICU nurses. MEASUREMENTS AND MAIN RESULTS To estimate validity, paired assessments (four/patient) compared the MAAS result with the subjective assessment using a 10-cm visual analog sedation scale, the percent change in blood pressure and heart rate from the previous 4-hr baselines, and the number of recent agitation-related sequelae. To estimate reliability, paired assessments (four/patient) measured correlation between assessments of the same type (e.g., MAAS-MAAS). Generalized estimating equations, which accounted for the four repeated measures in each patient, supported MAAS validity by finding a linear trend between MAAS and the visual analog scale (p < .001), blood pressure (p < .001), heart rate (p < .001), and agitation-related sequelae (p < .001) end points. The MAAS (kappa = 0.83 [95% confidence interval, 0.72 to 0.94]) was found to be more reliable than subjective assessment using the visual analog scale (intraclass correlation coefficient = 0.32 [95% confidence interval, 0.05 to 0.55]). CONCLUSIONS The MAAS is a valid and reliable sedation scale for use with mechanically ventilated patients in the SICU. Further studies are warranted regarding the effect of MAAS implementation in our SICU on patient outcomes, such as quality of sedation and length of mechanical ventilation, as well as the use of the MAAS in other patient populations (e.g., medical).

Abstract
Between December 1, 1994 and April 1,1998, 44 thoracoscopic procedures were performed in 42 patients following chest injuries. Indications included exploration in 15, retained haemothorax in 10, continued bleeding after chest tube placement in 3, air leak in 5 and empyema in 11. Video thoracoscopy was used in 24 cases and rigid thoracoscopy in 20, including 14 patients in whom video thoracoscopy was contraindicated. There was no difference in the operative times, length of stay or incidence of complications. Two formal and 3 "mini" thoracotomies were used in the video thoracoscopy group. Three "mini" thoracotomies were required in the rigid thoracoscopy group. Rigid thoracoscopy is an effective tool that, in selected cases, increases the utility of thoracoscopy in the management of chest trauma and its complications.

Abstract
OBJECTIVE To test the hypothesis that standardizing the process of weaning from mechanical ventilation would decrease ventilation times and length of stay in a surgical intensive care unit. DESIGN Comparison of historic ventilation times with physician-directed weaning with those obtained with protocol-guided weaning by respiratory therapists. SETTING Urban, teaching surgical intensive care unit with open admission policy and no dominant diagnosis related group. RESULTS From January 1, 1995, through December 31, 1995, 378 patients who underwent physician-directed weaning from a ventilator had 64488 hours of ventilation, compared with 57796 ventilation hours in 515 patients with protocol-guided weaning (April 1, 1996, through May 31, 1997). The mean hours of ventilation decreased by 58 hours, a 46% decrease (P<.001). The length of hospital stay decreased by 1.77 days (29% change), while the Acute Physiology and Chronic Health Evaluation III score remained at 50 to 51. The number of reintubations did not change. The marginal cost savings was $603580. CONCLUSION Protocol-guided weaning from mechanical ventilation leads to more rapid extubation than physician-directed weaning and has great potential for cost savings.

Abstract
Mechanical ventilation is one of the most common medical therapies administered within ICUs. Similarly, the "weaning" or "liberation" of patients from mechanical ventilation is a common and extremely important task performed in ICUs and specialized ventilator units within hospitals. Various methods exist for assessing a patient's readiness to be liberated from mechanical ventilation and for conducting the weaning process. Clinicians working in ICUs frequently develop their own personal preferences regarding the best approach to weaning patients from ventilatory support. Therefore, variability in the practice of weaning patients from mechanical ventilation is frequently demonstrated, even within a single ICU. Recently, several randomized clinical trials have produced conflicting results regarding the best technique for carrying out the weaning process (e.g., spontaneous breathing trials, intermittent mandatory ventilation, pressure-support ventilation). Such conflicting findings have further illustrated the complexity of the weaning process and the difficulties in identifying the "best" medical practices for carrying out this endeavor. However, other investigations have suggested that the selection of an individual technique for weaning patients from mechanical ventilation may not be as important as employing a systematic approach to this medical process. Protocol-guided weaning of mechanical ventilation in the ICU setting, often performed by nonphysicians, has gained in acceptance as a result of these investigations. We describe the recent experiences of three ICUs which have demonstrated significant improvements in patient outcomes (e.g., shorter durations of mechanical ventilation, lower incidence of ventilator-associated pneumonia, fewer patient complications) as a result of implementing formal weaning protocols. Our hope is that these data will assist other hospitals in developing their own systematic guidelines and protocols for weaning patients from mechanical ventilation.

Abstract
STUDY OBJECTIVE To determine the role of rigid thoracoscopy and continuous pleural irrigation as an alternative to thoracotomy in critically ill patients. DESIGN/SETTING/PATIENTS/INTERVENTIONS: Thirteen patients with empyema (one bilateral) underwent thorascopic decortication and continuous postoperative irrigation with normal saline solution. Seven patients required preoperative ventilator support. MEASUREMENTS AND RESULTS Double-lumen intubation was utilized in only two cases. Empyemas were drained effectively in all patients, including nine patients in whom dense adhesions were encountered. Mean duration of irrigation was 3.5 +/- 0.5 days. There were no deaths. One patient developed a recurrent empyema 1 week after resolution of symptoms and underwent thoracotomy. CONCLUSIONS Rigid thorascopic decortication is an effective method for treating empyemas and can be considered before thoracotomy. It can be performed in patients who might not be candidates for video-assisted thorascopic approaches owing to inability to tolerate one-lung anesthesia or who have dense adhesions preventing lung collapse.

Abstract
OBJECTIVE The aim of this study was to compare simultaneously stapled pneumonectomy (SSP) with individual ligation (IND) as a method for performing urgent pneumonectomy (Py) for trauma. METHODS Twelve patients who required Py were reviewed. SSP was performed in nine cases and IND in three cases. The two groups had statistically similar injury severity scores, presenting systolic blood pressures, and Trauma and Injury Severity Score derived probabilities of survival. An animal model of Py was developed, in which seven animals underwent SSP and seven underwent IND methods. Burst pressures of the pulmonary artery and bronchus were calculated after 14 days. RESULTS There were no differences noted in survival rates between SSP (5 (56%)) and IND (1 (33%)), nor in incidence of bronchopleural fistula. The SSP group had a significantly shorter operative time compared with that of IND (88.9 +/- 14.3 minutes vs 213 +/- 57.8 minutes, respectively, p - 0.01). The animal study revealed no difference in burst pressures of the bronchus (SSP = 662.9 +/- 169.9 mm Hg vs. IND = 591.4 +/- 193.2 mm Hg, p = 0.752) or of the pulmonary artery (SSP = 554.3 +/- 195.1 mm Hg vs. IND = 477.7 +/- 247.5 mm Hg, p = 0.529). CONCLUSION Survival after pulmonary injuries that require Py depends upon the rapidity of hilar control and of the procedures itself. Simultaneously stapled pneumonectomy is an effective and rapid method of dealing with such rare injuries.

Abstract
Bar code technology has been used for 5 years to improve the efficiency of identifying and documenting clinical pharmacy services at our institution. Data for an entire year (1993) were analyzed to quantify the nature and magnitude of pharmacy services provided for critically ill patients in intensive care units (ICU). Patients in the medical (MICU), respiratory (RICU), intermediate (IMU), and surgical (SICU) units (3234/3743 patients, 86%) were reviewed. Clinical interventions and expected outcomes were documented by pharmacists using an automated bar code system. There were 11,628 pharmacotherapy interventions, 3.6/patient; 12/pharmacist work day. Of patients whose drug therapy was reviewed at least once, 50% (1610/3234) received at least one intervention. The mean number of interventions/patient was 7.2 in the MICU, 6.1 in RICU, 3.4 in IMU, and 2.4 in the SICU, corresponding to APACHE III scores of 71.2, 66.2, 42.8, and 43.3, respectively. The majority of interventions were to modify dosages of antimicrobial agents, and were performed to achieve optimum efficacy (42%) and to minimize toxicity (46.2%). These data support the necessity for pharmacists to provide individualized care to critically ill patients.

Abstract
A surgeon has many options available to aid in the closure of abdominal wall defects in the elective setting. In the emergent setting, active infection or contamination increases the likelihood of infection of permanent prosthetic material and limits the surgical options. In such settings, we have used absorbable mesh (Dexon) as an adjunct to fascial closure until the acute complications resolve. To evaluate the effectiveness of this technique, we reviewed the outcome of such closures in 26 critically ill patients. Between July 1987 and June 1993, 26 patients were identified who had placement of absorbable mesh as part of an emergent laparotomy at a major urban trauma center. Through a retrospective chart review, the incidence of complications and outcome of the closure were tabulated. Seven patients were initially operated on for trauma. Two of the patients had mesh placement at their initial procedure secondary to fascial loss from trauma. The remainder of the patients hd mesh placement during a subsequent laparotomy for complications related to their initial procedure. Indications for these laparotomies included combinations of wound dehiscence, intra-abdominal abscess, anastomotic disruption, and perforation. Mesh placement in patients with intra-abdominal infection created effectively open abdominal wounds that allowed continued abdominal drainage, but required extensive wound care. Despite the absorbable nature of the mesh and often prolonged hospital stay in these ill patients, none of them required reoperation for dehiscence, recurrence of intra-abdominal abscess, or infection of the mesh.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To compare the hemodynamics of closed-chest cardiac massage vs. open-chest cardiac massage in patients resuscitated from cardiac arrest that occurred outside of the hospital. DESIGN Prospective, non-outcome, case series. SETTING Large urban emergency department. PATIENTS Ten adult, normothermic, nontraumatic, out-of-hospital, cardiac arrest patients who failed advanced cardiac life support (ACLS) therapy. INTERVENTIONS Patients presenting to the hospital in cardiac arrest were managed according to the ACLS protocol at the clinician's discretion. Proximal aortic and central venous pressure catheters were placed to measure arteriovenous compression- and relaxation-phase pressure gradients. After 5 mins of baseline measurements during closed-chest cardiac massage, patients underwent a left lateral thoracotomy, and open-chest cardiac massage was performed for 5 mins. MEASUREMENTS AND MAIN RESULTS The mean coronary perfusion pressure and compression-phase pressure gradients were 7.3 +/- 5.7 and 6.2 +/- 5.4 mm Hg, respectively, during closed-chest cardiac massage, while increasing to 32.6 +/- 17.8 and 32.6 +/- 29.9 mm Hg, respectively, during open-chest cardiac massage. The differences between both measurements were statistically significant (p < .05). CONCLUSIONS Open-chest cardiac massage is superior to closed-chest cardiac massage in providing relaxation-phase and compression-phase pressure gradients during cardiac arrest in patients failing current ACLS protocols. During open-chest cardiac massage, all patients exceeded the minimum coronary perfusion pressure of 15 mm Hg, which is recommended to obtain a return of spontaneous circulation. Further outcome studies are needed to determine the timeliness and appropriate indications for open-chest cardiac massage.

Abstract
Primary closure of the common bile duct following exploration has been safely and effectively performed, as advocated by Halsted, provided no evidence of pancreatitis, cholangitis, or ampullary obstruction exists. Using this precedent, the operative management and clinical course of 29 patients undergoing common bile duct exploration (CBDE) for choledocholithiasis from 1986 to 1992 were reviewed. Ten patients had primary closure of the common bile duct (CBD) following choledochotomy and exploration, and 17 patients had t-tube placement. Two patients had CBDE through an enlarged cystic duct that was then ligated. Patients were selected for t-tube placement if they had pancreatitis, ascending cholangitis, evidence of retained stones, or ampullary obstruction. Two patients in this series died. No patient with primary closure of the CBD suffered a biliary complication including retained stones, biliary fistula, pancreatitis, or bile peritonitis. Serious systemic complications were comparable in both groups. The results of this series support the safety of primary common bile duct closure in selected cases.

Abstract
Ambient temperature-induced hypothermia noted in trauma patients is frequently accompanied by a bleeding diathesis despite "laboratory normal" coagulation values. To document this impression, the following experiment was conducted. Coagulation studies and platelet function studies were performed in ten minipigs during induced whole body hypothermia (40 degrees C to 34 degrees C) and rewarming. Cooling was achieved in 2 to 3 hours and rewarming took 4 to 5 hours. In addition, similar coagulation and platelet function studies were conducted on plasma samples from the same animals that were cooled and then rewarmed in a water bath. Platelet counts and function as measured by Sonoclot analysis and aggregation did not decrease significantly with hypothermia in either model. Plasma cooled in a water bath demonstrated abnormal PT and aPTT (p < 0.001). Whole body hypothermia demonstrated abnormal bleeding time and PT (p < 0.001). Ambient temperature-induced hypothermia produced significant coagulation defects in a porcine model. Some of the coagulation defects were most pronounced during rewarming.

Abstract
To evaluate what has been the most effective surgical treatment for massive lower gastrointestinal bleeding, we reviewed the records of 31 patients who underwent colon resection for hemodynamic instability and/or the need for continued transfusions. These 31 patients underwent either segmental colectomy (21 patients) or subtotal colectomy (10 patients). Resections were performed for diverticular disease (19 patients), angiodysplasia (eight patients), acute ulceration (three patients), and polyps (one patient). The re-bleeding rate (mean follow-up 1 year) for subtotal colectomy was 0 per cent, segmental resection with positive angiography was 14 per cent, and segmental resection with negative angiography was 42 per cent. The complication rate including myocardial infarction, ARDS, pneumonia, and renal failure was highest (83 per cent) in those patients receiving segmental resection with a negative angiogram. The mortality rate was also highest for segmental resection patients with negative angiography (57 per cent). The results of this review suggest that segmental resection should be performed when the bleeding site is identified angiographically. Subtotal colectomy should be reserved for massive bleeding with negative angiography.

Abstract
Arterial injuries of the thoracic outlet are complex and require a precise plan for adequate management and prompt exposure of injured vessels. Our 10-year experience with 28 such injuries is reviewed. Arteriography was performed whenever possible in stable patients (15) and aided in planning the operative approach. Unstable patients with active bleeding, pulsatile or expanding hematoma, or pulse deficit were taken to the operating room without delay. A thoracic approach was required in 15 patients, and the exposure was extrathoracic in 12 patients. Airway was secured with liberal use of emergency endotracheal intubation (16 patients). Primary repair was possible in 16 patients, with grafting performed in eight and ligation in three. One vertebral artery injury was successfully controlled with embolization. Venous injuries were repaired in six patients and ligation was necessary in eight; there was no significant morbidity. Two patients died in this series from complications of severe hemorrhage. Significant morbidity was encountered from associated neurologic injuries in 15 patients. Stroke was evident in two patients, both of whom were moribund preoperatively. Proximal subclavian artery injuries were particularly more problematic and frequently required an interim anterior thoracotomy for early control of exsanguinating hemorrhage. Our philosophy in the management of these injuries and choices of exposure are discussed in detail.

Abstract
This investigation compares the accuracy of calculating gentamicin pharmacokinetic parameters by a noninvasive body composition technique (bioelectrical impedance analysis; BIA) with an empiric method, against the two-point method as the criterion standard. A prospective concurrent open label design was used. The 32 medical and surgical intensive care unit beds at Henry Ford Hospital, a not-for-profit, university-affiliated teaching hospital, served as the setting. Twenty critical ill adults, Therapeutic Index Scoring System (TISS) = 4, who required gentamicin as part of their normal course of therapy for gram-negative bacillary infections, were evaluated. Gentamicin Vd and k were calculated by three methods. After measurement of body composition parameters by BIA, previously derived gentamicin dosing equations were used to predict gentamicin volume of distribution (Vd) and elimination rate constant (k) (BIA method). Empiric estimates of these parameters (Vd = 0.3L/kg and k derived from creatinine clearance) were compared with the BIA parameters against a criterion standard Vd and k determined from a two-point sampling of gentamicin serum concentrations. Measurements of BIA parameters and gentamicin serum concentrations were made in duplicate with coefficients of variation, < or = 2% and < or = 3%, respectively. The BIA and empiric methods produced resultant pharmacokinetic parameters (Vd and k) not different than those measured by the two-point method. There were no statistically significant differences in mean error (bias), or mean squared error (precision) for both Vd and k assessed by the empiric or BIA methods.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The operative management and clinical course of 17 patients treated for severe pancreatico-duodenal injuries from 1983 to 1990 was reviewed. The etiology of these injuries was gunshot wound in 15 patients; stab wound in 1 patient; and a motor vehicle accident in 1 patient. Seven patients presented in shock with a systolic blood pressure of less than 80. At exploration, 57 associated injuries were found in the 17 patients including 16 major vascular injuries. All patients were treated with pyloric exclusion and drainage. Vagotomy was performed in eight patients. None of these 17 patients were felt to have extensive enough damage to require pancreatico-duodenectomy. Two patients died in the immediate postoperative period of severe coagulopathy and two patients died of sepsis. Seven patients had complications related to the pancreatico-duodenal injury. All seven developed pancreatic fistulas; three also had pancreatitis and two developed multiple enterocutaneous fistulas. Systemic complications included pulmonary complications in eight patients and sepsis in five patients, including two patients with abdominal abscesses. Six patients bled in the immediate postoperative period secondary to coagulopathy. Three patients had complications related to pyloric exclusion. One developed afferent loop syndrome necessitating reoperation. The other two had marginal ulcers, which either perforated or bled and required reoperation. Of interest, neither of these two patients had vagotomy initially. The results of this series confirm the effectiveness of pyloric exclusion with vagotomy for severe pancreatico-duodenal injury.

Abstract
The use of potentially contaminated shed blood and the contribution of autotransfused blood to coagulopathy are controversial issues associated with intraoperative blood salvage (IBS) in trauma patients. Intraoperative blood salvage was used in 154 trauma patients and resulted in reinfusion of 7.97 units per patient. Moderate to severe abnormalities of the prothrombin time (PT) and partial thromboplastin time (PTT) occurred in 39 patients (31%). Prolongation of the PT and PTT occurred with increasing transfusion. Coagulopathy was seen in patients receiving greater than 15 IBS units and in patients receiving greater than 50 combined units of blood. Of the 66 patients with bowel injury, 58 patients received shed blood. Patients with bowel injury showed no increase in infection but did develop prolongation of PT and PTT at lower levels of IBS transfusion. Based on the results of this study, patients receiving greater than 15 units of IBS transfusion require careful monitoring and factor replacement, and IBS transfusion should be limited to less than 10 units in patients with bowel injury.

Abstract
The management of 25 pregnant patients (gestational age 4-40 weeks) treated at Henry Ford Hospital from 1980-86 was reviewed. Eleven women were treated for a variety of nontraumatic general surgical emergencies including cholecystitis, appendicitis, pancreatitis, and gastrointestinal obstruction. Fourteen women were treated after sustaining traumatic injuries. Ten patients were managed without operation and 15 required surgical intervention as part of their treatment. Diagnostic studies that proved helpful included diagnostic peritoneal lavage, ultrasonography, intravenous pyelography, and roentgenograms of the chest and abdomen. There were no maternal deaths, but two fetal deaths occurred as a result of traumatic injuries. Five women and one neonate developed major complications requiring prolonged hospitalization. Early aggressive resuscitation and thorough diagnostic evaluation are required to achieve a favorable outcome in the management of the pregnant patient who presents with an emergent general surgical problem.

Abstract
The specialty of organ transplantation has grown tremendously during the past decade. With the advent of cyclosporine, artificial organs, and organ-assist devices, the possibility of suitable patients with end-stage organ disease becoming successful transplant recipients has increased dramatically. Consequently, the need for donor organs has risen. The greatest source of potential organ-tissue donors exists in the acute care setting (ie, emergency departments and intensive care units). To meet the need for this increasing demand, emergency physicians must become familiar with the techniques of procurement. Part 1 defines the problem of procurement and presents financial, historic, organizational, legal, and psychosocial aspects of organ-tissue procurement. A synopsis of brain death concludes the discussion. Part 2 (February 1990) presents aspects of the evaluation, selection, maintenance, and management of the organ-tissue donor. Disease transmission and controversial issues in organ-tissue procurement also are discussed.

Abstract
Diagnostic peritoneal lavage (DPL), liver-spleen scintigraphy (LSS), and visceral angiography (VA) have been cited as useful in the evaluation of patients sustaining blunt abdominal trauma to determine the existence of injuries requiring operative intervention. We have reviewed the clinical courses of 44 patients who sustained blunt abdominal trauma and had various combinations of DPL, LSS, and VA employed in their diagnostic evaluation. The predictive value and efficiency of these tests have been compared in this group of patients. DPL is sensitive and specific for the presence of intraperitoneal blood. LSS is sensitive and specific for parenchymal irregularity in the liver and spleen. VA is sensitive and specific for vascular abnormality, severe hemorrhage, and arteriovenous shunting. None of these tests are completely sensitive and specific for the spectrum of surgically significant injuries produced by blunt abdominal trauma. In this group of patients who had multiple studies because of diagnostic uncertainty, DPL had the highest predictive value and the highest efficiency. LSS results did not by themselves dictate a change in management for any patient. In some patients VA was helpful in determining operative or nonoperative management.

Abstract
We describe the difficulties in diagnosing a pancreatic injury in two patients with multiple injuries who did not have an obvious need for a celiotomy. Multiple diagnostic tests were employed, but in each patient, there was a delay in the diagnosis of the injury. A pancreatic injury may evolve over time so that repetitive clinical diagnostic studies may be required to evaluate the condition of these patients.

Abstract
A retrospective review of 229 patients with a final diagnosis of small-bowel obstruction was undertaken to evaluate the role of contrast radiography in the management of their conditions. In 84 patients (37%) the clinical findings and plain abdominal roentgenograms were sufficient for diagnosis and subsequent management. Of the remaining 145 patients with equivocal findings, 27% had an upper gastrointestinal series, 29% a barium enema, and 44% had both. Useful information (complete obstruction, unobstructed passage of contrast, or diagnosis other than adhesional obstruction) was obtained from 86% of the radiographic studies. Three patients had negative contrast studies yet eventually underwent adhesiolysis (enterolysis) and were classified as false-negative. Two patients had evidence of high-grade obstruction yet had nonoperative resolution and were classified as false-positive. The mortality in the contrast group (7%) was not statistically different than that in the no-contrast group (7%). Contrast radiography is a safe and effective means of increasing diagnostic accuracy in patients with presumed small-bowel obstruction.

Abstract
Urban trauma, often presumed to be an acute episodic event, may actually be a chronic recurrent disease related to the lifestyle, environment, and other factors of its victims. To test this idea an attempt was made to obtain 5-year followup for 501 consecutive survivors of violent trauma seen at one hospital, 1980-1981. Followup information for these patients was obtained from medical records at four local Level I trauma centers, death certificates, Medical Examiner's records, and police crime computer files. Of the 501 patients, 263 had medical followup including 148 patients with one trauma and 115 patients with recurrent trauma. Of these 263 patients, 200 (76%) were unemployed and 164 (62%) abused alcohol or drugs. From 1982-1987 142 out of 263 patients were involved in 133 crimes and 52 died. These data suggest that urban trauma is a chronic disease with a recurrent rate of 44% and a 5-year mortality rate of 20%.

Abstract
Between 1983 and 1987, 114 adult patients with 131 pneumothoraces were treated utilizing catheter aspiration for simple pneumothorax as an alternative to tube thoracostomy. The causes of simple pneumothorax were as follows: 79 needle-induced, 36 spontaneous, and 16 traumatic. Thirty-eight of the pneumothoraces were small (less than 20% of volume), 55 were moderate (20% to 40% of volume), 36 were large (greater than 40% of volume), and 2 were of unknown size. Overall, catheter aspiration for simple pneumothorax was successful in 90 patients (69%). The success rate was 75% with needle-induced, 53% with spontaneous, and 75% with traumatic pneumothoraces. Small pneumothoraces were successfully managed with catheter aspiration for simple pneumothorax in 87% of patients, moderate-sized in 60%, and large in 61%. There were three complications (2.3%), including one hemothorax and two retained sheared catheter tips. The average cost per patient was +868 for catheter aspiration, and $6402 for a tube thoracostomy. These data support catheter aspiration as a safe, cost-effective, and successful technique for managing simple pneumothorax.

Abstract
In this prospective, comparative study, 129 patients who sustained penetrating abdominal trauma were randomized to receive preoperatively, and for 3-5 days postoperatively, one of three antibiotic regimens: Group I--cefotaxime (CTX) (2 Gm Q8H), Group II--cefoxitin (2 Gm Q6H), or Group III--clindamycin (900 mg Q8H) and gentamicin (3-5 mg/kg/day in divided doses Q8H). The three groups were similar in terms of the following: age, sex, severity of injury, number of organs injured, colon injuries, shock, blood transfusions, or positive intraoperative cultures. Septic complications occurred as follows: Group I--6.9%, Group II--2.3%, and Group III--6.9%. The three regimens ranked as follows in terms of therapy costs: CTX less than cefoxitin less than clindamycin and gentamicin. It is concluded that single agent therapy with a cephalosporin is preferable to combination therapy on the basis of equivalent effectiveness, lower toxicity, and lower costs.

Abstract
In this open, prospective, comparative study, 75 patients who sustained penetrating abdominal trauma were randomised to receive 1 of 3 antibiotic regimens preoperatively and for 3 to 5 days postoperatively. Group I received cefotaxime 2g 8-hourly, group II received cefoxitin 2g 6-hourly and group III received clindamycin (900 mg 8-hourly) and gentamicin 3 to 5 mg/kg/day in divided doses 8-hourly. The 3 groups were not statistically different in terms of age, sex, severity of injury, number of organs injured, colon injuries, shock, blood transfusions or positive intra-operative cultures. Septic complications occurred in 8% of patients in group I, in 4% of group II patients and in 8% of group III patients. Cefotaxime was the least costly regimen, followed by cefoxitin, then clindamycin and gentamicin. It may be concluded that single agent therapy with a broad spectrum cephalosporin is preferable to combination therapy on the basis of equivalent effectiveness, less toxicity and lower costs.

Abstract
To determine the relationship between severity of illness and mortality, therapeutic intervention score (TISS) and acute physiology score (APS) were determined on admission to the Surgical Intensive Care Unit (SICU). Patients were divided into survivors and nonsurvivors and differences were compared by chi-square analysis. The 1524 patients admitted to the SICU during a 12-month period had a mean TISS of 3.03 and a mean APS of 13. The average length of stay (LOS) was 3.75 days. Of the 1524 patients, 97 (6.4%) died. The number of nonsurvivors increased with higher TISS and APS scores (P less than 0.001). There were no deaths in the TISS Category 1 patients or in the APS 0-5 group. Mortality rates dramatically increased with APS greater than 20 (P less than 0.001). There were 1286 patients with APS less than 20, and 24 (2%) of these patients died, whereas 73 (31%) of 238 patients with APS greater than 20 died. Nonsurvivors had a mean TISS of 3.6, mean APS of 27, and LOS of 4.88 days, all of which totals were higher than the survivors' totals. In this study population, risk of death was one in three if the APS was greater than 20. These data indicate that TISS and APS scores are effective means of assessing mortality risk in SICU patients.
