[PMID: 38444023 PMCID: PMC10913451 DOI: 10.1186/s13741-024-00368-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 02/22/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND Postoperative respiratory failure is the most frequent complication in postsurgical patients. The purpose of this study is to assess whether pulmonary function testing in high-risk patients during preoperative assessment detects previously unknown respiratory impairments which may influence patient outcomes. METHODS A targeted patient screening by spirometry and the measurement of the diffusing capacity of the lung for carbon monoxide (DLCO) was implemented in the anesthesia department of a tertiary university hospital. Patients of all surgical disciplines who were at least 75 years old or exhibited reduced exercise tolerance with the metabolic equivalent of task less than four (MET < 4) were examined. Clinical characteristics, history of lung diseases, and smoking status were also recorded. The statistical analysis entailed t-tests, one-way ANOVA, and multiple linear regression with backward elimination for group comparisons. RESULTS Among 256 included patients, 230 fulfilled the test quality criteria. Eighty-one (35.2%) patients presented obstructive ventilatory disorders, out of which 65 were previously unknown. 38 of the newly diagnosed obstructive disorders were mild, 18 moderate, and 9 severe. One hundred forty-five DLCO measurements revealed 40 (27.6%) previously unknown gas exchange impairments; 21 were mild, 17 moderate, and 2 severe. The pulmonary function parameters of forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and DLCO were significantly lower than the international reference values of a healthy population. Patients with a lower ASA class and no history of smoking exhibited higher FVC, FEV1, and DLCO values. Reduced exercise tolerance with MET < 4 was strongly associated with lower spirometry values. CONCLUSIONS Our screening program detected a relevant number of patients with previously unknown obstructive ventilatory disorders and impaired pulmonary gas exchange. This newly discovered sickness is associated with low metabolic equivalents and may influence perioperative outcomes. Whether optimized management of patients with previously unknown impaired lung function leads to a better outcome should be evaluated in multicenter studies.

Abstract
INTRODUCTION Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly performed procedure for pancreaticobiliary disease. While ERCP is highly effective, it is also associated with the highest adverse event (AE) rates of all commonly performed endoscopic procedures. Thus, it is critical that endoscopists and caregivers of patients undergoing ERCP have clear understandings of ERCP-related AEs. AREAS COVERED This narrative review provides a comprehensive overview of the available evidence on ERCP-related AEs. For the purposes of this review, we subdivide the presentation of each ERCP-related AE according to the following clinically relevant domains: definitions and incidence, proposed mechanisms, risk factors, prevention, and recognition and management. The evidence informing this review was derived in part from a search of the electronic databases PubMed, Embase, and Cochrane, performed on 1 May 20231 May 2023. EXPERT OPINION Knowledge of ERCP-related AEs is critical not only given potential improvements in peri-procedural quality and related care that can ensue but also given the importance of reviewing these considerations with patients during informed consent. The ERCP community and researchers should aim to apply standardized definitions of AEs. Evidence-based knowledge of ERCP risk factors should inform patient care decisions during training and beyond.

Perioperative Optimization of the Cardiac Surgical Patient. Can J Cardiol 2023; 39:497-514.

Abstract
Perioperative optimization of cardiac surgical patients is imperative to reduce complications, utilize health care resources efficiently, and improve patient recovery and quality of life. Standardized application of evidence-based best practices can lead to better outcomes. Although many practices should be applied universally to all patients, there are also opportunities along the surgical journey to identify patients who will benefit from additional interventions that will further ameliorate their recovery. Enhanced recovery programs aim to bundle several process elements in a standardized fashion to optimize outcomes after cardiac surgery. A foundational concept of enhanced recovery is attaining a better postsurgical end point for patients, in less time, through achievement and maintenance in their greatest possible physiologic, functional, and psychological state. Perioperative optimization is a broad topic, spanning multiple phases of care and involving a variety of medical specialties and nonphysician health care providers. In this review we highlight a variety of perioperative care topics, in which a comprehensive approach to patient care can lead to improved results for patients, providers, and the health care system. A particular focus on patient-centred care is included. Although existing evidence supports all of the elements reviewed, most require further improvements in implementation, as well as additional research, before their full potential and usefulness can be determined.

Nocturnal respiratory abnormalities among ward-level postoperative patients as detected by the Capnostream 20p monitor: A blinded observational study. PLoS One 2023; 18:e0280436. [PMID: 36662703 PMCID: PMC9858304 DOI: 10.1371/journal.pone.0280436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 01/01/2023] [Indexed: 01/21/2023] Open
Abstract
PURPOSE This prospective observational study aimed to establish the frequency of postoperative nocturnal respiratory abnormalities among patients undergoing major surgery who received ward-level care. These abnormalities may have implications for postoperative pulmonary complications (PPCs). METHODS Eligible patients underwent blinded noninvasive continuous capnography with pulse oximetry using the Capnostream™ 20p monitor over the first postoperative night. All patients received oxygen supplementation and patient-controlled opioid analgesia. The primary outcome was the number of prolonged apnea events (PAEs), defined as end-tidal carbon dioxide (EtCO2) ≤5 mmHg for 30-120 seconds or EtCO2 ≤5 mmHg for >120 seconds with oxygen saturation (SpO2) <85%. Secondary outcomes were the proportion of recorded time that physiological indices were aberrant, including the apnea index (AI), oxygen desaturation index (ODI), integrated pulmonary index (IPI), and SpO2. Exploratory analysis was conducted to assess the associations between PAEs, PPCs, and pre-defined factors. RESULTS Among 125 patients who had sufficient data for analysis, a total of 1800 PAEs occurred in 67 (53.4%) patients. The highest quartile accounted for 89.1% of all events. Amongst patients who experienced any PAEs, the median (IQR) number of PAE/patient was four (2-12). As proportions of recorded time (median (IQR)), AI, ODI, and IPI were aberrant for 12.4% (0-43.2%), 19.1% (2.0-57.1%), and 11.5% (3.1-33.3%) respectively. Only age, ARISCAT, and opioid consumption/kg were associated with PPCs. CONCLUSIONS PAE and aberrant indices were frequently detected on the first postoperative night. However, they did not correlate with PPCs. Future research should investigate the significance of detected aberrations.

Variation in Prevertebral Soft Tissue Swelling after Staged Combined Multilevel Anterior-Posterior Complex Cervical Spine Surgery: Anterior Then Posterior (AP) versus Posterior Then Anterior-Posterior (PAP) Surgery. J Clin Med 2022; 11:jcm11237250. [PMID: 36498824 PMCID: PMC9741360 DOI: 10.3390/jcm11237250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 11/26/2022] [Accepted: 12/03/2022] [Indexed: 12/12/2022] Open
Abstract
The influence of the sequence of surgery in the development of prevertebral soft tissue swelling (PSTS) in staged combined multilevel anterior-posterior complex spine surgery was examined. This study was conducted as a retrospective study of patients who underwent staged combined multilevel anterior-posterior complex cervical spine surgery from March 2014 to February 2021. Eighty-two patients were identified, of which fifty-seven were included in the final analysis after screening. PSTS was measured from routine serial monitoring lateral cervical radiographs prior to and after surgery for five consecutive days at each cervical level from C2 to C7 in patients who underwent anterior then posterior (AP) and posterior then anterior-posterior (PAP) surgery. The mean PSTS measurements significantly differed from the preoperative to postoperative monitoring days at all cervical levels (p = 0.0000) using repeated measures analysis of variance in both groups. PSTS was significantly greater in PAP than in AP at level C2 on postoperative day (POD) 1 (p = 0.0001). PSTS was more prominent at levels C2-4 during PODs 2-4 for both groups. In staged combined multilevel anterior-posterior complex spine surgery, PSTS is an inevitable complication. Therefore, surgeons should monitor PSTS after surgery when performing anterior-posterior complex cervical spine surgery, especially in the immediate postoperative period after PAP surgery.

Identification of risk factors for postoperative pulmonary complications in general surgery patients in a low-middle income country. PLoS One 2022; 17:e0274749. [PMID: 36219615 PMCID: PMC9553039 DOI: 10.1371/journal.pone.0274749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 09/05/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Postoperative pulmonary complications (PPCs) are an important cause of perioperative morbidity and mortality. Although risk factors for PPCs have been identified in high-income countries, less is known about PPCs and their risk factors in low- and middle-income countries, such as South Africa. This study examined the incidence of PPCs and their associated risk factors among general surgery patients in a public hospital in the province of KwaZulu-Natal, South Africa to inform future quality improvement initiatives to decrease PPCs in this clinical population. METHODS A retrospective secondary analysis of adult patients with general surgery admissions from January 1, 2013 to December 31, 2017 was conducted using data from the health system's Hybrid Electronic Medical Registry. The sample was comprised of 5352 general surgery hospitalizations. PPCs included pneumonia, atelectasis, acute respiratory distress syndrome, pulmonary edema, pulmonary embolism, prolonged ventilation, hemothorax, pneumothorax, and other respiratory morbidity which encompassed empyema, aspiration, pleural effusion, bronchopleural fistula, and lower respiratory tract infection. Risk factors examined were age, tobacco use, number and type of pre-existing comorbidities, emergency surgery, and number and type of surgeries. Bivariate and multivariable logistic regression models were conducted to identify risk factors for developing a PPC. RESULTS The PPC rate was 7.8%. Of the 418 hospitalizations in which a patient developed a PPC, the most common type of PPC was pneumonia (52.4%) and the mortality rate related to the PPC was 11.7%. Significant risk factors for a PPC were increasing age, greater number of comorbidities, emergency surgery, greater number of general surgeries, and abdominal surgery. CONCLUSIONS PPCs are common in general surgery patients in low- and middle-income countries, with similar rates observed in high-income countries. These complications worsen patient outcomes and increase mortality. Quality improvement initiatives that employ resource-conscious methods are needed to reduce PPCs in low- and middle-income countries.

Abstract
If we define the human body by the mass of the elements that compose it, we could say that we are oxygen and other elements. Oxygen, in addition to being fundamental in our composition, is an element that we constantly need to support cellular respiration and, therefore, life. Interestingly, despite its importance, humans have not developed mechanisms that allow us to store it and, therefore, we are unable to sustain life if we are deprived of ventilation, even for brief periods. Accordingly, the ability to induce the cessation of ventilation in a patient must be accompanied by different technical and non-technical skills that allow the patient's safety to be maintained in this highly vulnerable state. Through the use of basic mathematical tools and comparative physiology, we hereby propose to review the physiological foundations of preoxygenation to understand the reasons behind the clinical recommendations in this field.

Abstract
Purpose Managing pediatric patients requiring daily general anesthesia (GA) for radiation therapy (RT) in the setting of COVID-19 is complex, owing to the aerosolizing nature of GA procedures, the risk of cardiopulmonary complications for infected patients, and the treatment of immunocompromised oncology patients in a busy, densely populated radiation oncology clinic. Methods and Materials We developed an institutional protocol to define procedures for COVID-19 testing and protection of patients, caregivers, and staff, hypothesizing that this protocol would allow patients requiring GA to be safely treated, minimizing COVID-19 transmission risk to both patients and staff, and at the same time maintaining pre–COVID-19 patient volumes. All patients underwent COVID-19 testing before their first treatment and thrice weekly during treatment. For patients who tested positive for COVID-19, RT was delivered in the last end-of-day treatment appointment. A negative pressure room was used for GA induction and recovery, and separate physician/nurse teams were designated for in-room versus out-of-room patient management. Results Seventy-eight pediatric patients received RT under GA, versus 69 over the same prior year timeframe, and 2 patients received 2 courses of RT under GA, for a total of 80 courses. The mean age was 4.9 years (range, 0.5-19.0 years) and 41 of 78 (52.6%) were male. Two patients (2.6%) received 2 courses of RT under GA, establishing a total of 80 courses. The mean number of treatment fractions was 22.2 (range, 1-40). Two of 78 patients (2.6%) tested positive for COVID-19; both were asymptomatic. Both patients completed treatment as prescribed. Neither patient developed cardiopulmonary symptoms complicating anesthesia, and neither patient experienced grade 3+ acute radiation toxicity. Conclusions With careful multidisciplinary planning to mitigate COVID-19 risk, pediatric RT with GA was carried out for a large patient volume without widespread infection and without increased toxic effects from either GA or RT.

Abstract
BACKGROUND Obesity is a growingly impacting human health concern. Laparoscopic sleeve gastrectomy (LSG) is an effective treatment for morbid obesity. However, the general anesthesia (GA) used in this major surgery has its documented drawbacks in obese patients with high risk. On the other hand, combined thoracic spinal-epidural anesthesia (CTSEA), a modern regional anesthesia procedure, has the advantages of both spinal and epidural anesthesia but without their shortcomings. This prospective study is a case experience that assesses the feasibility of CTSEA as an anesthesia option for laparoscopic sleeve gastrectomy (LSG). METHODS A total of 100 patients were recruited for LSG as a management procedure for morbid obesity, which was performed under CTSEA. Perioperative events, functional parameters, and patients' satisfaction scores were recorded. RESULTS Our prospective study showed successful use of CTSEA in 99% of the patients, except for one patient (1%) in whom CTSEA was converted into GA due to severe pain and anxiety. Few adverse events occurred and were managed accordingly. The satisfaction score revealed that 94% of the patients were satisfied. CONCLUSIONS CTSEA was a successful anesthetic alternative procedure for LSG surgery.

[PMID: 34015036 PMCID: PMC8136676 DOI: 10.1371/journal.pone.0251795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Accepted: 05/01/2021] [Indexed: 11/23/2022] Open
Abstract
Bronchodilators dilate the bronchi and increase lung volumes, thereby improving respiratory physiology in patients with chronic obstructive pulmonary disease (COPD). However, their effects on sevoflurane kinetics remain unknown. We aimed to determine whether inhaled salbutamol affected the wash-in and wash-out kinetics of sevoflurane and the occurrence of early postoperative pulmonary complications (PPCs) in patients with COPD undergoing elective surgery. This randomized, placebo-controlled study included 63 consecutive patients with COPD allocated to the salbutamol (n = 30) and control groups (n = 33). The salbutamol group received salbutamol aerosol (2 puffs of ~200 μg) 30 min before anesthesia induction and 30 min before surgery completion. The control group received a placebo. Sevoflurane kinetics were determined by collecting end-tidal samples from the first breaths at 1, 2, 3, 4, 5, 7, 10, and 15 min before the surgery (wash-in) and after closing the vaporizer (wash-out). PPCs were recorded for 7 days. The salbutamol group had higher end-tidal to inhaled sevoflurane ratios (p<0.05, p<0.01) than the control group, from 3 to 10 min during the wash-in period, but no significant differences were observed during the wash-out period. The arterial partial pressure of oxygen to the fraction of inhaled oxygen was significantly higher in the salbutamol group at 30 (320.3±17.6 vs. 291.5±29.6 mmHg; p = 0.033) and 60 min (327.8±32.3 vs. 309.2±30.5 mmHg; p = 0.003). The dead space to tidal volume ratios at 30 (20.5±6.4% vs. 26.3±6.0%, p = 0.042) and 60 min (19.6±5.1% vs. 24.8±5.5%, p = 0.007) and the incidence of bronchospasm (odds ratio [OR] 0.45, 95% confidence interval [CI] 0.23–0.67, p = 0.023) and respiratory infiltration (OR 0.52, 95% CI, 0.40–0.65, p = 0.017) were lower in the salbutamol group. In patients with COPD, salbutamol accelerates the wash-in rate of sevoflurane and decreases the occurrence of postoperative bronchospasm and pulmonary infiltration within the first 7 days.

[PMID: 33839130 DOI: 10.1016/j.athoracsur.2021.03.082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 03/17/2021] [Accepted: 03/24/2021] [Indexed: 11/01/2022]
Abstract
BACKGROUND Postoperative respiratory failure, defined as ventilator dependency for more than 48 hours or unplanned reintubation within 30 days, is a costly complication of cardiac surgery that increases mortality and length of stay. Stratification of patients by risk upon intensive care unit admission could identify cases requiring early measures to prevent respiratory failure. This study aimed to develop and validate a risk score for postoperative respiratory failure after cardiac surgery. METHODS This retrospective analysis of 4262 patients admitted to the cardiovascular intensive care unit after major cardiac surgery between 01/2013 and 12/2017, used the Society of Thoracic Surgeons database and ventilator data from the respiratory therapy department. Patients were randomly and equally assigned to development and validation cohorts. Covariates used in the multivariable models were assigned weighted points proportional to their β regression coefficient values to create the risk score, which categorized patients into low, medium, and high risk of postoperative respiratory failure. RESULTS In both cohorts, postoperative respiratory failure risk was significantly different between risk categories. Compared to low-risk patients, moderate-risk patients had a two times greater risk, and high-risk patients had a four to seven times greater risk. Body mass index, previous cardiac surgery, cardiopulmonary bypass, cardiogenic shock, pulmonary disease presence, baseline functional status, hemodynamic instability, and number of blood products used intraoperatively were significant predictors of respiratory failure. CONCLUSIONS This risk score can stratify patients by risk for developing postoperative respiratory failure after major cardiac surgery, which may help in the development of preventive measures.

Abstract
BACKGROUND The purpose of this study was to examine the effects of an intraoperative MgSO4 infusion on arterial oxygenation and lung mechanics in patients with moderate COPD undergoing cancer larynx surgery under general anesthesia (GA). Our primary outcome was arterial oxygenation determined by the PaO2 and PaO2 /FiO2 . The secondary outcomes were lung mechanics (peak airway pressure, airway plateau pressure, dead space, lung compliance, airway resistance) and postoperative complications. METHODS In this randomized controlled double-blinded trial, 40 patients with an ASA classifications II and/or III who were diagnosed with moderate COPD and who were scheduled for cancer larynx surgery under GA were randomly allocated into two equal groups, the target (Mg group) and control group (C group). In the Mg group, 30 mg/kg of 10% MgSO4 solution was administered intravenously for over 20 minutes as the loading dose, followed by the continuous infusion of 10 mg/kg/hr In the C group, the same loading and maintenance infusion rates were administered using 0.9% saline. RESULTS Unlike the C group (baseline "T0" to post-infusion "T1" interval 294 ± 97 vs 238 ± 71 mm Hg, respectively, P = .04 ± SD), the Mg group exhibited preserved intraoperative PaO2 (T0 to T1 interval 271 ± 89 vs 257 ± 53 mm Hg, respectively, P = .54 ± SD) and PaO2 /FiO2 (C group T0 to T1 interval 404 ± 81 vs 349 ± 84, P = .04 and Mg group 394 ± 91 vs 379 ± 95, P = .61, respectively), and these effects were modest. Further, compared to the C group, the Mg group exhibited lower airway resistance, dead space, airway plateau pressure, and peak airway pressure, and higher dynamic compliance. The postoperative PaO2 and PaO2 /FiO2 were higher in the Mg group compared to the C group. CONCLUSIONS Intraoperative infusion of MgSO4 in patients with moderate COPD undergoing laryngectomy surgery under GA produces mild perioperative protective effects on both arterial oxygenation and lung mechanics.

Abstract
The number of orthopedic surgeries performed in the United States has increased substantially over the past several years. The most recent data available from the Agency for Healthcare Research and Quality indicate that five of the 10 operative procedures most commonly performed during inpatient stays involve the musculoskeletal system. Cigarette smoking is one of the most prevalent and preventable risk factors for musculoskeletal disorders and orthopedic surgery complications. This article discusses the effects of smoking on bone health, the importance of smoking cessation among patients scheduled for or recovering from orthopedic surgery, and the vital role nurses play in supporting patient efforts to lead a tobacco-free life.

Abstract
Fibrodysplasia ossificans progressiva (FOP) is a rare disease in which heterotopic ossification (HO) is formed in muscles, tendons and ligaments. Traumatic events, including surgery, are discouraged as this is known to trigger a flare-up with risk of subsequent HO. Anesthetic management for patients with FOP is challenging. Cervical spine fusion, ankylosis of the temporomandibular joints, thoracic insufficiency syndrome, restrictive chest wall disease, and sensitivity to oral trauma complicate airway management and anesthesia and pose life-threatening risks. We report a patient with FOP suffering from life-threatening antibiotic resistant bacterial infected ulcers of the right lower leg and foot. The anesthetic, surgical and postoperative challenges and considerations are discussed. In addition, the literature on limb surgeries of FOP patients is systemically reviewed. The 44 year-old female patient was scheduled for a through-knee amputation. Airway and pulmonary evaluation elicited severe abnormalities, rendering standard general anesthesia a rather complication-prone approach in this patient. Thus, regional anesthesia, supplemented with intravenous analgosedation and N2O-inhalation were performed in this case. The surgery itself was securely planned to avoid any unnecessary tissue damage. Postoperatively the patient was closely monitored for FOP activity by ultrasound and [18F]PET/CT-scan. One year after surgery, a non-significant amount of HO had formed at the operated site. The systematic review revealed seventeen articles in which thirty-two limb surgeries in FOP patients were described. HO reoccurrence was described in 90% of the cases. Clinical improvement due to improved mobility of the operated joint was noted in 16% of the cases. It should be noted, though, that follow-up time was limited and no or inadequate imaging modalities were used to follow-up in the majority of these cases. To conclude, if medically urgent, limb surgery in FOP is possible even when general anesthesia is not preferred. The procedure should be well-planned, alternative techniques or procedures should be tested prior to surgery and special attention should be paid to the correct positioning of the patient. According to the literature recurrent HO should be expected after surgery of a limb, even though it was limited in the case described.

Abstract
Background Anesthetic drugs may directly or indirectly affect respiratory function. We investigated the effects of intravenous propofol and inhaled sevoflurane anesthesia on postoperative spirometric indices in patients undergoing inguinal herniorrhaphy surgery. Methods We randomly assigned 111 patients, aged 18 - 65 years, undergoing inguinal herniorrhaphy surgery, to receive either intravenous propofol or inhaled sevoflurane. Forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and FEV1/FVC were measured before and after anesthesia. Comparisons between the two groups were made using the t-test and ANOVA. Results There were no significant differences between the two groups in terms of age, sex, height, body weight, BMI, pain score, ASA class, operation duration, and received analgesics. The FEV1 and FVC values significantly decreased after the operation in the sevoflurane group. Conclusions Both intravenous propofol and inhaled sevoflurane can decrease postoperative spirometry parameters. However, it seems that patients receiving propofol have less decreased spirometric indices.

Abstract
BACKGROUND Pancreatic cancer is a disease of the elderly. Surgical resection is usually offered to patients in early stage disease; however, pancreatic resection in the elderly is controversial. METHODS MEDLINE, EMBASE and Cochrane Library, were searched for studies comparing short- and long-term outcomes of elderly (above the age of 70) with non-elderly patients (below the age of 70) following pancreatic resection for pancreatic adenocarcinoma over the period from the inception of electronic database to 2017. Twelve articles documenting 4860 patients were included. A meta-analysis of data on patient characteristics, operative techniques, and perioperative outcomes were analysed. Our primary endpoint was postoperative mortality, defined as 30-day mortality or in-hospitalisation mortality. RESULTS There were 919 patients in the elderly group and 3941 patients in the non-elderly group. Elderly patients had worse ASA scores (p < 0.001) and more cardiovascular comorbidities (p = 0.002). Tumour size, T-stage, N-stage and tumour grade were similar between the elderly and non-elderly group (p > 0.05). Fewer elderly patients received a concomitant venous resection with their pancreatectomy (RR0.80, p = 0.003, I2 = 0%), achieved a negative margin status (RR0.76, p = 0.02, I2 = 28%) and underwent adjuvant chemotherapy treatment (RR0.69, p < 0.001, I2 = 42%). Overall complication (RR1.15, p < 0.001, I2 = 47%), in particular, respiratory complications (RR2.33, p = 0.004, I2 = 39%), was higher in the elderly group. There was no difference in postoperative pancreatic fistula formation, postoperative haemorrhage, intraabdominal abscess and length of hospital stay between both groups (p > 0.05). Postoperative mortality was similar between both groups (p = 0.17). Subgroup analysis according to the time of enrolment (<2000, ≥2000) showed a significant subgroup effect (Chi2 = 3.44, p = 0.06, I2 = 70.9%) and revealed that postoperative mortality in the elderly group improved over time (Before 2000: n = 1654, subtotal RR2.27, p = 0.02, I2 = 0%; From 2000 onwards: n = 3206, subtotal RR1.00, p = 0.99, I2 = 0%). CONCLUSION Fewer elderly patients received chemotherapy and portal vein resection to achieve a clear margin. Pancreatic resection of pancreatic adenocarcinoma can be performed safely on elderly patients with acceptable risks in experienced centres by specialist hepatobiliary surgeons. Age alone should not be the only determinant for the selection of patients for surgical treatment of pancreatic adenocarcinoma.

Abstract
Abstract
Editor’s Perspective
What We Already Know about This Topic
What This Article Tells Us That Is New
Background
Positive end-expiratory pressure (PEEP) increases lung volume and protects against alveolar collapse during anesthesia. During emergence, safety preoxygenation preparatory to extubation makes the lung susceptible to gas absorption and alveolar collapse, especially in dependent regions being kept open by PEEP. We hypothesized that withdrawing PEEP before starting emergence preoxygenation would limit postoperative atelectasis formation.
Methods
This was a randomized controlled evaluator-blinded trial in 30 healthy patients undergoing nonabdominal surgery under general anesthesia and mechanical ventilation with PEEP 7 or 9 cm H2O depending on body mass index. A computed tomography scan at the end of surgery assessed baseline atelectasis. The study subjects were thereafter allocated to either maintained PEEP (n = 16) or zero PEEP (n = 14) during emergence preoxygenation. The primary outcome was change in atelectasis area as evaluated by a second computed tomography scan 30 min after extubation. Oxygenation was assessed by arterial blood gases.
Results
Baseline atelectasis was small and increased modestly during awakening, with no statistically significant difference between groups. With PEEP applied during awakening, the increase in atelectasis area was median (range) 1.6 (−1.1 to 12.3) cm2 and without PEEP 2.3 (−1.6 to 7.8) cm2. The difference was 0.7 cm2 (95% CI, −0.8 to 2.9 cm2; P = 0.400). Postoperative atelectasis for all patients was median 5.2 cm2 (95% CI, 4.3 to 5.7 cm2), corresponding to median 2.5% of the total lung area (95% CI, 2.0 to 3.0%). Postoperative oxygenation was unchanged in both groups when compared to oxygenation in the preoperative awake state.
Conclusions
Withdrawing PEEP before emergence preoxygenation does not reduce atelectasis formation after nonabdominal surgery. Despite using 100% oxygen during awakening, postoperative atelectasis is small and does not affect oxygenation, possibly conditional on an open lung during anesthesia, as achieved by intraoperative PEEP.

Abstract
Patients undergoing emergency surgery may present with the acute respiratory distress syndrome (ARDS) or develop this syndrome postoperatively. The incidence of ARDS in the postoperative period is relatively low, but the impact of ARDS on patient outcomes and healthcare costs is relevant Aakre et.al (Mayo Clin Proc 89:181-9, 2014).The development of ARDS as a postoperative pulmonary complication (PPC) is associated with prolonged hospitalisation, longer duration of mechanical ventilation, increased intensive care unit length of stay and high morbidity and mortality Ball et.al (Curr Opin Crit Care 22:379-85, 2016). In order to mitigate the risk of ARDS after surgery, the anaesthetic management and protective mechanical ventilation strategies play an important role. In particular, a careful integration of general anaesthesia with neuraxial or locoregional techniques might promote faster recovery and reduce opioid consumption. In addition, the use of low tidal volume, minimising plateau pressure and titrating a low-moderate PEEP level based on the patient's need can improve outcome and reduce intraoperative adverse events. Moreover, perioperative management of ARDS patients includes specific anaesthesia and ventilator settings, hemodynamic monitoring, moderately restrictive fluid administration and pain control.The aim of this review is to provide an overview and evidence- and opinion-based recommendations concerning the management of patients at risk of and with ARDS who undergo emergency surgical procedures.

Abstract
BACKGROUND Respiratory function would be impaired during general anesthesia period. Researchers devoted their energies to finding effective strategies for protecting respiratory function. Low tidal volume, positive end-expiratory pressure (PEEP), and lung recruitment maneuvers (LRMs) were recommended for patients under mechanical ventilation. However, based on the current evidence, there was no consensus on whether LRMs should be routinely used for anesthetized patients with healthy lungs, and the benefits of them remained to be determined. MATERIALS AND METHODS To evaluate the benefits of LRMs on patients undergoing surgery with general anesthesia, we searched relevant studies in PubMed, EMBASE, Ovid Medline and the Cochrane Library up to June 30, 2018. The primary outcome was postoperative pulmonary complications (PPCs). RESULTS Twelve trials involving 2756 anesthetized patients were included. The results of our study showed a significant benefit of LRMs for reducing the incidence of PPCs (RR = 0.67; 95%CI, 0.49 to 0.90; P<0.05; Chi2 = 32.94, p for heterogeneity = 0.0005, I2 = 67%). After subgroup analyses, we found LRMs combining with lung protective ventilation strategy and sustained recruitment maneuvers were associated with reducing the occurrence of PPCs. The results also revealed that the use of LRMs improved PaO2/FiO2 in non-obese patients, but with extremely high heterogeneity (I2 = 95%). CONCLUSION According to the findings from contemporary meta-analysis, LRMs combining with lung protective ventilation strategy may have an association with decreasing in the incidence of PPCs and improvement of oxygenation on non-obese patients. However, the conclusions must be interpreted cautiously as the outcome may be influenced dramatically due to varied LRMs and ventilation patterns.

Abstract
PURPOSE To study nurse anesthetists' experiences of key factors for successful airway management in general anesthesia of adult obese patients. DESIGN The study was a qualitative observational study with a descriptive approach. METHODS Eight semistructured interviews were conducted. Data were analyzed using the critical incident technique. FINDINGS Five key factors for successful general anesthesia of adult obese patients were identified. These factors were preparing and planning the anesthesia, optimizing patient position, optimizing ventilation through proper preoxygenation and increasing positive end-expiratory pressure, quickly securing the airway, and working in teams. CONCLUSIONS Knowledge of key factors that facilitate and improve the anesthesia care of obese patients is important to provide safe and quality anesthesia to this patient group as obese patients often have small margins and urgent situations can quickly arise. This knowledge enables the nurse anesthetist to be one step ahead and to be ready to take action if complications occur.

Abstract
Background With the increasing amount of geriatric surgery, it has become a great challenge for anesthesiologists to reduce the incidence of postoperative pulmonary complications (PPCs). The two most popular airway management methods, laryngeal mask airway (LMA) and endotracheal intubation (ETI), both have their unique advantages in specific clinical settings. For the purpose of helping clinicians make better decisions on airway management during geriatric surgery, we designed this multi-center clinical trial to compare the influence of LMA and ETI on PPCs. Methods/design In this multi-center, randomized, parallel clinical trial, a total of 6000 elderly patients, aged ≥ 70 years, with an American Society of Anesthesiologists classification level of 1–2 and a body mass index ≤ 35 kg/m2, undergoing elective surgery will be enrolled and randomized into the LMA or the ETI group. Both groups will receive usual perioperative care except for the adoption of LMA/ETI. Primary outcomes are the occurrence of PPCs and patients’ perioperative mortality rates. Ease of intubation, anesthetics consumption, treatment for PPCs, duration of surgery, anesthesia recovery time and performance, time of PPC onset, postanesthesia care unit stay, intensive care unit admission and stay, in-hospital days, re-admission rates, hospitalization cost, and patients’ satisfactory scores will be secondary outcomes. Follow-up will be conducted through phone-call visits until 12 weeks after discharge. Discussion This trial will assess the possible benefits or disadvantages of perioperative LMA use in elderly patients compared with ETI regarding the occurrence of PPCs and clinical prognosis. We expect that this trial will also add to the current understanding of PPCs in geriatric populations and contribute to the international recommendations of geriatric surgery management.

Gastrointest Endosc 2019; 89:855-862.

Abstract
BACKGROUND AND AIMS ERCP is a complex procedure often performed in patients at high risk for sedation-related adverse events (SRAEs). However, there is no current standard of care with regard to mode of sedation and airway management during ERCP. The aim of this study was to assess the safety of general endotracheal anesthesia (GEA) versus propofol-based monitored anesthesia care (MAC) without endotracheal intubation in patients undergoing ERCP at high risk for SRAEs. METHODS Consecutive patients undergoing ERCP at high risk for SRAEs at a single center were invited to participate in this randomized controlled trial comparing GEA and MAC. Inclusion criteria were STOP-BANG score ≥3, abdominal ascites, body mass index ≥35, chronic lung disease, American Society of Anesthesiologists class >3, Mallampati class 4 airway, and moderate to heavy alcohol use. Exclusion criteria were preceding EUS, emergent ERCP, tracheostomy, unstable airway, gastric outlet obstruction or delayed gastric emptying, and altered foregut anatomy. The primary endpoint was composite incidence of SRAEs: hypoxemia, use of airway maneuvers, hypotension requiring vasopressors, sedation-related procedure interruption, cardiac arrhythmia, and respiratory failure. Secondary outcomes included procedure duration, cannulation success, in-room time, and immediate adverse events. RESULTS Two hundred patients (mean age, 61.1 ± 13.6 years; 36.5% women) were randomly assigned to GEA (n = 101) or MAC (n = 99) groups. Composite SRAEs were significantly higher in the MAC group compared with the GEA group (51.5% vs 9.9%, P < .001). This was primarily driven by the frequent need for airway maneuvers in the MAC group. Additionally, ERCP was interrupted in 10.1% of patients in the MAC group to convert to GEA because of respiratory instability refractory to airway maneuvers (n = 8) or significant retained gastric contents (n = 2). There were no statistically significant differences in cannulation, in-room, procedure, or fluoroscopy times between the 2 groups. All patients undergoing GEA were successfully extubated in the procedure room at completion of ERCP, and Aldrete scores in recovery did not differ between the 2 groups. There were no immediate adverse events. CONCLUSION In patients at high risk for SRAEs undergoing ERCP, sedation with GEA is associated with a significantly lower incidence of SRAEs, without impacting procedure duration, success, recovery, or in-room time. These data suggest that GEA should be used for ERCP in patients at high risk for SRAEs (Clinical trial registration number: NCT02850887.).

Abstract
The severity of the clinical condition and co-morbidities of the patients for esophagectomy require a complex assessment and risk stratification before the operation, and most of the cases need complex management. We did a literature search and considered the data on risk stratification and complex management of patients who undergo thoracic surgery. Smoking cessation programs can protect against complications, which is related to the respiratory system, the heart and the convalescence of the wounds in postoperative condition, but the timing is critical due to the operation. A complex team of physicians and healthcare professionals, as well as respiratory prehabilitation, can help to improve the clinical condition, chest kinematics, lung mechanics, peripheral and respiratory muscle function, metabolism and quality of life of this type of patients. We need to consider a complex risk stratification before esophagectomy and require complex management for these patients, including smoking cessation and respiratory prehabilitation, to improve the post-operative complications.

Abstract
Postoperative pulmonary complications are common and cause increased mortality and hospital stay. Smoking and respiratory diseases including asthma, chronic obstructive pulmonary disease and obstructive sleep apnoea are associated with developing postoperative pulmonary complications. Independent risk factors for such complications also include low pre-operative oxygen saturation, or a recent respiratory infection. Postponing surgery in patients who have respiratory infections or inadequately treated respiratory disease, until these can be fully treated, should, therefore, reduce postoperative pulmonary complications. There is evidence from several studies that pre-operative smoking cessation reduces such complications, with no agreed duration at which the benefits become significant; the longer the abstinence, the greater the benefit. Intensive smoking cessation programmes are more effective, and there are long-term benefits, as many patients become permanent non-smokers following their surgery. Supervised exercise programmes normally last 6-8 weeks, and although they reduce overall complications, the evidence of benefit for postoperative pulmonary complications is mixed. High-intensity interval training can improve fitness in just 2 weeks, and so may be more useful for surgical patients. Specific respiratory pre-operative interventions, such as deep breathing exercises and incentive spirometry, can help when used as components of a package of respiratory care. Pre-operative inspiratory muscle training programmes that involve inspiration against a predetermined respiratory load may also reduce some postoperative pulmonary complications. Pre-operative exercise programmes are recommended for patients having major surgery, or in those where pre-operative testing has shown low levels of cardiorespiratory fitness; interval training or respiratory interventions are more feasible as these reduce complications after a shorter pre-operative intervention.

Abstract
STUDY OBJECTIVES There is growing evidence internationally to support Enhanced Recovery After Surgery (ERAS) pathways. The impact of pathway compliance and the relative importance of individual components, however, remains less clear. Our institution implemented a multimodal ERAS protocol for elective colorectal surgery in November 2013. The objectives of this study were to investigate the impact of the introduction of the pathway, the relationship between pathway adherence and patient outcomes, and the relative importance of individual components. DESIGN This was a single-center, observational cohort study of elective colorectal surgical patients. SETTING A tertiary care and academic teaching hospital in Canada. PATIENTS Prospective data was collected from 495 consecutive major colorectal surgical patients following the ERAS launch. Retrospective data was also collected from a pre-ERAS cohort of 99. MEASUREMENTS Adherence to 12 ERAS components were measured, along with American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) defined patient complications and hospital length of stay (LOS). Post-ERAS patients were divided in to two groups: high compliance (≥75% process adherence) and low compliance (<75% adherence). Outcomes were compared between groups. MAIN RESULTS There was a significant reduction in both complication rate (31.5% vs 14.6%; p ≤0.05) and hospital mean LOS (10.1 vs 6.9 days; p ≤0.05) following introduction of the ERAS pathway. The high adherence group had a shorter mean LOS (5.7 vs 8.6 days; p ≤0.01) and lower rate of complications (11.2% vs 19.6%; p = 0.02) compared with the low compliance group. CONCLUSIONS Higher adherence to the standardized ERAS protocol was associated with improved patient outcomes, including reduced pulmonary complications. The cause-effect relationship is complex and likely influenced by confounding factors. Our data provides feedback to aid ongoing innovation of our pathway locally and adds to the growing body of evidence supporting the value of ERAS in general.
