The Effect of Pilates on Quality of Sleep, Aerobic Capacity and Anaerobic Power in Premenopausal Women.

Pilates is a holistic exercise focused on respiration, body control, and accuracy of movements, and it improves respiratory muscle strength, balance, quality of life, and overall physical performance. However, little is known about the effect of Pilates on sleep quality. The purpose of the present prospective observational study was to evaluate the effect of four months of Pilates training on the quality of sleep, aerobic capacity, and anaerobic power in premenopausal women. The sample consisted of 53 premenopausal women: one experimental group ( n = 40) and one control group ( n = 13). Participants in the experimental group received at least three one-hour sessions of Pilates exercise per week for 16 weeks. The two groups were similar at baseline. After 4 months of Pilates, the intervention group had significantly lower scores on the Athens Insomnia Scale, Epworth Sleepiness Scale, and autonomic arousal index compared to the baseline scores. The intervention group presented significant improvement in aerobic fitness, muscle strength, flexibility, balance, abdominal muscle endurance, as well as in the general health and social functioning subscales of the 36-Item Short Form Health Survey (SF-36). Pilates workouts appeared to improve sleep quality in premenopausal women, as well as the basic parameters of fitness and quality of life.

The Total Intra Venous Anesthesia Effect Versus Volatile Anesthesia, on Stress and Pain Levels, in Patients Undergoing Breast Reconstruction in Ambulatory Surgery Center Total Intra Venous Anesthesia Protocol and Stress Response.

AIM: To compare pain and stress response through cortisol and DHEA levels, implementing. Total intra venous anesthesia (TIVA) versus general anesthesia with volatile anesthetics (VOL). DESIGN: This is a prospective randomized correlation study with consecutive measurements. METHODS: In an ambulatory surgical center from October of 2019 to August of 2020, patients who underwent breast reconstruction with autologous fat grafting were randomized into 2 groups. Patients in the TIVA group (n = 23) received intravenous anesthesia and those in the VOL group (n = 23) received volatile anesthesia (desflurane). Demographic, anthropometric and clinical data were recorded. Arterial systolic (SP) and diastolic (DP) blood pressure, heart rate and oxygen saturation were recorded. Pain and stress levels were evaluated through salivary cortisol and DHEA levels at 4 different time points: T0) 1 hour before induction, T1) during the induction, T2) during anesthesia maintenance, and T3) in recovery phase. Statistical analysis was performed with SPSS 25.0 at significant level α = .05. FINDINGS: There were no statistically significant differences between the 2 groups regarding demographic features. Interestingly that there was a statistically significant difference in the vital sign monitoring where patients in the TIVA group reported with higher levels of SP(T2) and DP (T2), whilst DHEA (T1) levels was correlated positively with patient's age and cortisol (T1) levels and negatively with DP (T3). CONCLUSIONS: This study supports the use of TIVA as a safe and effective option for anesthesia in patients undergoing breast reconstruction with autologous fat grafting.

A randomised trial of intracavitary electrocardiography versus surface landmark measurement for central venous access device placement.

BACKGROUND: Malpositioned central venous access devices (CVADs) can lead to significant patient injury including central vein thrombosis and dysrhythmias. Intra-cavitary electrocardiography (IC ECG) has been recommended by peak professional bodies as an accurate alternative for bedside CVAD insertion, to reduce risk of malposition and allowing immediate use of the device. Our objective was to compare the effect of IC ECG on CVAD malposition compared to traditional institutional practice for CVAD placement. METHODS: Randomised controlled trial of IC ECG CVAD insertion verses traditional CVAD insertion (surface landmark measurement with post insertion x ray). Patient recruitment was from December 2016 to July 2018. The setting was a 900-bed tertiary referral hospital based in South Western Sydney, Australia. Three hundred and forty-four adult patients requiring CVAD insertion for intravenous therapy, were enrolled and randomly allocated (1:1 ratio) to either IC-ECG (n = 172) or traditional (n = 172) CVAD insertion. Our primary outcome of interest was the rate of catheters not requiring repositioning after insertion (ready for use). Secondary outcomes were comparison of procedure time and cost. RESULTS: Of the 172 patients allocated to the IC ECG method, 170 (99%) were ready for use immediately compared to 139 of the 172 (81%) in the traditional insertion group (difference, 95% confidence interval (CI): 18%, 11.9-24.1%). The total procedure time was mean 15 min (SD 8 min) for IC ECG and mean 36 min (SD 17 min) for traditional CVAD insertion (difference-19.9 min (95% CI-14.6 to -34.4). IC ECG guided CVAD insertion had a cost reduction of AUD $62.00 per procedure. CONCLUSIONS: Using IC-ECG resulted in nearly no requirement for post-insertion repositioning of CVADs resulting in savings in time and cost and virtually eliminating the need for radiographic confirmation. TRIAL REGISTRATION: This trial is registered at the Australian New Zealand Clinical Trials Registry (http://www.anzctr.org.au). The registration number is ACTRN12620000919910.

European recommendations on the proper indication and use of peripheral venous access devices (the ERPIUP consensus): A WoCoVA project.

Since several innovations have recently changed the criteria of choice and management of peripheral venous access (new devices, new techniques of insertion, new recommendations for maintenance), the WoCoVA Foundation (WoCoVA = World Conference on Vascular Access) has developed an international Consensus with the following objectives: to propose a clear and useful classification of the currently available peripheral venous access devices; to clarify the proper indication of central versus peripheral venous access; discuss the indications of the different peripheral venous access devices (short peripheral cannulas vs long peripheral cannulas vs midline catheters); to define the proper techniques of insertion and maintenance that should be recommended today. To achieve these purposes, WoCoVA have decided to adopt a European point of view, considering some relevant differences of terminology between North America and Europe in this area of venous access and the need for a common basis of understanding among the experts recruited for this project. The ERPIUP Consensus (ERPIUP = European Recommendations for Proper Indication and Use of Peripheral venous access) was designed to offer systematic recommendations for clinical practice, covering every aspect of management of peripheral venous access devices in the adult patient: indication, insertion, maintenance, prevention and treatment of complications, removal. Also, our purpose was to improve the standardization of the terminology, bringing clarity of definition, and classification.

Factors affecting adult intensive care units costs by using the bottom-up and top-down costing methodology in OECD countries: A systematic review.

OBJECTIVES: To review the studies, which calculated the total intensive care unit costs and indicated the main cost drivers in the intensive care by using either top-down, bottom-up approach or the combination of them. RESEARCH METHODOLOGY/DESIGNS: A systematic review of papers published until October 2020 was conducted. Search was performed on PubMed, Medline, Scopus and Science Direct databases. SETTING: This review i examined costs in adult intensive care units, in countries belonging to the Organisation for Economic Co-operation and Development (OECD) (medical, surgical or general adult , paediatric and neonatal were not included). MAIN OUTCOME MEASURES: Eighteen articles were included in the review. RESULTS: Eight of the studies used the top-down costing methodology, six of them used the bottom-up approach and four of them used both of them. The mean total patient cost per day ranged from €200.75 to €4321.91 (all costs are presented in 2020 values for euro). Human resources were identified as the largest proportion of total costs. Length of stay, mechanical ventilation, continuous haemodialysis and severe illness are the main cost drivers of intensive care unit total costs. CONCLUSION: There are a variety of methods and study designs used to calculate costs of an intensive care unit stay.t It is necessary to evolve standardised costing methods in order to make comparisons and succeed in cost-effective management.

GAVeCeLT-WoCoVA Consensus on subcutaneously anchored securement devices for the securement of venous catheters: Current evidence and recommendations for future research.

BACKGROUND: Subcutaneously anchored securement devices (or subcutaneous engineered securement devices) have been introduced recently into the clinical practice, but the number of published studies is still scarce. The Italian Group of Long-Term Central Venous Access Devices (GAVeCeLT)-in collaboration with WoCoVA (World Congress on Vascular Access)-has developed a Consensus about the effectiveness, safety, and cost-effectiveness of such devices. METHODS: After the definition of a panel of experts, a systematic collection and review of the literature on subcutaneously anchored securement devices was performed. The panel has been divided in two working groups, one focusing on adult patients and the other on children and neonates. RESULTS: Although the quality of evidence is generally poor, since it is based mainly on non-controlled prospective studies, the panel has concluded that subcutaneously anchored securement devices are overall effective in reducing the risk of dislodgment and they appear to be safe in all categories of patients, being associated only with rare and negligible local adverse effects; cost-effectiveness is demonstrated-or highly likely-in specific populations of patients with long-term venous access and/or at high risk of dislodgment. CONCLUSION: Subcutaneously anchored securement is a very promising strategy for avoiding dislodgment. Further studies are warranted, in particular for the purpose of defining (a) the best management of the anchoring device so to avoid local problems, (b) the patient populations in which it may be considered highly cost-effective and even mandatory, (c) the possible benefit in terms of reduction of other catheter-related complications such as venous thrombosis and/or infection, and-last but not least-(d) their impact on the workload and stress level of nurses taking care of the devices.

Health-Related Quality of Life and Rehabilitation Costs of Patients with Amputated Limb.

AIM: The aim of this study was the evaluation of health-related quality of life (HRQoL) and rehabilitation costs of patients with amputated limb. MATERIALS AND METHODS: This is a cross-sectional study and the study sample, which was a sample of convenience, included 100 patients with amputated limb. The tools of the survey were the Short Form Questionnaire-36 (SF-36) and the Questionnaire used for measuring rehabilitation costs in trauma patients by Stergiannis et al.Results: The sample of the study consisted of 107 patients with amputation. HRQoL significantly increased (p < 0.001) between all-time points. According to the patients' answers, there were zero costs related to rehabilitation 1 year after the amputation. The type of edge amputation had significant impact on the rate of HRQoL increase. Rehabilitation costs increased over time during the first year. The mean (SD) rehabilitation cost was 1372 (2200) € at the first 6 months and 4774 (9109) € at the second half year. HRQoL was associated with age at all-time points and with costs of purchase of special pharmaceuticals, hospitalization, other expenses, number of medical visits, and cost of phone calls. CONCLUSIONS: The economic costs due to the amputation need to be studied as they affect the extent to which an amputated patient can meet his new emerging needs. Therefore, future research should focus in the economic dimension of the amputation in relation with the HRQoL of these patients and their relatives, so that new health policies may be conducted.

Effects of the Enhanced Recovery Program on the Recovery and Stress Response in Patients With Cancer Undergoing Pancreatoduodenectomy.

Aim the study was the comparison of enhanced recovery after surgery (ERAS) versus conventional care (CON) protocols in patients undergoing pancreatoduodenectomy with regard to pain intensity, emotional response (optimism/sadness/stress), and stress biomarker levels (adrenocorticotropopic hormone, cortisol). We conducted a prospective two-group randomized controlled study with repeated measures in 85 patients with cancer pancreatoduodenectomy. In the ERAS group (N = 44), the ERAS protocol was followed, compared with the CON group (N = 41). We assessed pain with the numeric rating scale and a behavioral scale (Critical Care Pain Observation Tool), emotional responses (numeric rating scale), and serum adrenocorticotropopic hormone and cortisol levels at three time points: T1, admission day; T2, day of surgery; and T3, discharge day (ERAS) or the fifth day of stay (CON). Data were analyzed by linear mixed modeling to account for repeated measurements. We observed decreased postoperative pain in ERAS patients after adjusting for confounders (p = .002) and a trend for less complications. No significant associations with stress/emotional responses were noted. Only age, but not protocol, appeared to have a significant effect on adrenocorticotropopic hormone levels despite a significant interaction with time toward increased adrenocorticotropopic hormone levels in the ERAS group. In conclusion, despite its fast track nature, ERAS is not associated with increased stress in patients undergoing pancreatoduodenectomy and is associated with decreased pain.

Factors Affecting Stress Levels in Hospitalized Patients after Implementation of Fast-Track Protocol in Hepatopancreatobiliary Surgery.

OBJECTIVE: The objective was to explore factors affecting stress levels in hospitalized patients after implementation of fast-track (FT) protocol in hepatopancreatobiliary surgery. METHODS: This was a prospective cross-sectional study, where 90 patients were included. Exploration of environmental postoperative stress levels was conducted by serum adrenocorticotropic hormone and cortisol levels, the Intensive Care Unit Environmental Stressor Scale, and three self-reported Numeric Analog Scale questions, with regard to emotional/stress level, specifically "How sad do you feel right now?" "How stressed do you feel right now?" and "How optimistic do you feel right now, about the future?" at 3 time points: (T1) Before surgery, (T2) the day of surgery, and (T3) the 3rd postoperative day. The trial profile is conformed according to the CONSORT guidelines. Statistical analysis was carried out by SPSS software version 22 (IBM SPSS software, Chicago, Illinois, USA) at a significance level of 0.05. RESULTS: Serum cortisol T2 levels were positively correlated with the day of removal the drainage tube (rho = 0.235, P = 0.027). Furthermore, serum cortisol T3 levels were positively correlated with age and body mass index and negatively with the day of drainage tube removal (rho = 0.231, P = 0.028, rho = 0.235, P = 0.026, and rho = -0.279, P = 0.008, respectively). CONCLUSIONS: The findings of this study highlight that after evaluation of stress levels; nurses could interfere and reduce stress levels, knowing the factors which cause the increased stress levels, after the implementation of FT protocols.

A Comparison of 2 Venous Puncture Sites for Peripheral Implanted Ports.

The use of peripheral implanted ports to administer parenteral nutrition in a number of patient cohorts is increasingly seen as a safe alternative to chest ports with equivalence in long-term outcomes. Two insertion sites on the upper arm were compared using the zone insertion method (ZIM), which was developed as an approach to optimize and reduce catheter-related exit site complications. The ZIM divides the medial upper arm into 3 main colors, red, green, and yellow, which are based on musculoskeletal, skin, and vessel characteristics. The optimal exit site is considered to be the green zone, the middle third of the upper arm. Thirty-five patients were allocated to vein puncture at the yellow/green zone (group A) and 35 patients at the yellow zone near the axilla (group B). All devices were implanted in the distal green zone. Successful peripheral port implantation was 91.4% (n = 35) for group A and 100.0% (n = 35) for group B (P = .07). No procedural or postprocedural complications were observed.

Peripherally inserted central catheter ports: A vascular access specialist's systematic approach.

Implanted ports are an important vascular access device for patients with malignancies requiring long-term chemotherapy. Peripherally placed ports are increasing in use as they are a safe, cost-effective alternative to chest-placed ports. Most peripheral ports can be placed bedside by specialist nurses in designated clinical areas rather than costly operating rooms or interventional radiology suites. Peripheral ports are considered less invasive compared with chest port placement because of reduced procedural risk. To enhance the success rate of peripheral port placement and minimize risks, we provide vascular access specialists with a systematic approach along with some technical advice tips and tricks to help avoid mechanical complications such as repeated puncture of the vein, excessive bleeding, thrombosis or skin dehiscence, as well as latent complications such as catheter migration and catheter-related blood stream infection.

Nurse understaffing is associated with adverse events in postanaesthesia care unit patients.

AIMS AND OBJECTIVES: To investigate the associations between nurse staffing and the incidence and severity of hypoxaemia, arterial hypotension and bradycardia of postoperative patients during their postanaesthesia care unit stay. BACKGROUND: Nurse understaffing has been associated with adverse patient outcomes in a variety of hospital settings. In the postanaesthesia care unit, nursing shortage is common and can be related to compromised prevention, detection and treatment of adverse events. DESIGN: Observational, single-centre, prospective study that adhered to Strengthening the Reporting of Observational studies in Epidemiology checklist (see Supporting information Appendix S1); 2,207 patients admitted to the postanaesthesia care unit of a tertiary care hospital over a 5-month period were enrolled. METHODS: Incidence of hypoxaemia (arterial oxygen saturation <95%), arterial hypotension (systolic blood pressure <90 mmHg) and bradycardia (heart rate <50 beats per minute), along with episode severity, was recorded. Patients were classified into three groups as follows: sufficient staffing, low and high understaffing. Risk for hypoxaemia, arterial hypotension and bradycardia was adjusted according to patient, anaesthesia and operation characteristics. RESULTS: The incidence of hypoxaemia was significantly higher in the high understaffing group patients, while the incidence of arterial hypotension was significantly higher in both low and high understaffing group patients, compared to sufficient staffing group ones. In the high understaffing group patients, hypoxaemia and arterial hypotension episodes were of significantly higher severity. CONCLUSIONS: These associations between hypoxaemia and arterial hypotension and postanaesthesia care unit understaffing indicate that care quality and patient safety can be compromised in case patient acuity is not matched with sufficient nursing resources. RELEVANCE TO CLINICAL PRACTICE: Higher incidence of hypoxaemia and arterial hypotension advocates for the prevention of imbalances between patient number and care demands and the number of available nurses.

Cross-Correlation Among Visual Analog, Observational, and Behavioral Pain Scales of Oncological Patients Undergoing Major Abdominal Surgery.

PURPOSE: To determine the perception of postoperative pain intensity between nurses and oncology patients undergoing major abdominal surgery. DESIGN: A prospective cross-correlation study with 173 oncology patients undergoing major abdominal surgery, such as hepatectomy or pancreatectomy. METHODS: Postoperative pain intensity was evaluated by clinical pain assessment tools such as critical-care pain observation tool (CPOT) and behavioral pain scale (BPS) recorded by the researcher, whereas the visual analog scale was completed by patients. Demographic and clinical data were recorded. FINDINGS: The Cronbach's α for CPOT and BPS was α = 0.738 for each. There was a significant correlation between CPOT and BPS (ρ = 0.796, P < .001), whereas the visual analog scale was correlated with CPOT and BPS (ρ = 0.351, P < .001 and ρ = 0.352, P < .001, respectively), showing that nurses did not underestimate patients' pain levels. CONCLUSIONS: The management of postoperative pain intensity after major abdominal surgery requires clinical comprehension by nurses to achieve the reduction or suppression of pain.

Fast-Track Recovery Program After Major Liver Resection: A Randomized Prospective Study.

The objective of this study was to compare fast-track (FT) recovery protocol with the conventional one in patients treated with major liver resection by evaluating perioperative morbidity, length of hospitalization, and readmission rate. Sixty-two patients suffering from malignant liver tumors were surgically treated from May 2012 to April 2014. After randomization, they were prospectively divided into two groups: Group A patients (n = 32) followed FT recovery protocol and Group B patients (n = 30) were treated with the conventional (CON) protocol. Postoperative morbidity, readmission rate, and median hospital stay in the two groups were studied. Fast-track protocol was associated with a decreased complication (25%, p = .002), whereas the risk of postoperative morbidity was 2.4 times higher in patients treated with the CON protocol (60%, p = .002). Readmission rate was not significantly different between the two groups (6.25%, p = .35). Age (p = .382) and body mass index (p = .818) were not a suspending factor for following the FT protocol. Overall length of stay (postoperative days) in the FT group was (mean ± SD) 5.75 ± .5 and in the CON group was 13.5 ± 6.7 (p < .001). Fast-track recovery protocol seems to be safe and particularly efficient in patients undergoing major liver resections.

Inadvertent hypothermia and mortality in critically ill adults: Systematic review and meta-analysis.

OBJECTIVE: Considering that inadvertent hypothermia (IH) is common in Intensive Care Unit (ICU) patients and can be followed by severe complications, this systematic review identified, appraised and synthesised the published literature about the association between IH and mortality in adults admitted to the ICU. DATA SOURCES: By using key terms, literature searches were conducted in Pubmed, CINAHL, Cochrane Library, Web of Science and EMBASE. REVIEW METHODS: According to PRISMA guidelines, articles published between 1980-2016 in English-language, peer-reviewed journals were considered. IH was defined as core temperature of <36.5°C or lower, present on ICU admission or manifested during ICU stay. Outcome measure included ICU, hospital or 28-day mortality. Selected cohort studies were evaluated with the Newcastle-Ottawa Scale. Extracted data were summarised in tables and synthesised qualitatively and quantitatively, with adjusted odds ratios (ORs) for mortality being combined in meta-analyses. RESULTS: Eighteen observational studies met inclusion criteria. All of them had high methodological quality. In twelve out of fifteen studies, unadjusted mortality was significantly higher in hypothermic patients compared to non-hypothermic ones. Likewise, in thirteen out of sixteen studies, IH or lowest core temperature was independently associated with significantly higher mortality. High severity and long duration of IH were also associated with higher mortality. Mortality was significantly higher in patients with core temperature <36.0°C (pooled OR 2.093, 95% CI 1.704-2.570), and in those with core temperature <35.0°C (pooled OR 2.945, 95% CI 2.166-4.004). CONCLUSIONS: These findings indicate that IH predicts mortality in critically ill adults and pose suspicion that this may contribute to adverse patient outcome.

Comparative Evaluation of Pain, Stress, Neuropeptide Y, ACTH, and Cortisol Levels Between a Conventional Postoperative Care Protocol and a Fast-Track Recovery Program in Patients Undergoing Major Abdominal Surgery.

BACKGROUND: Fast-track (FT) postoperative protocol in oncological patients after major abdominal surgery reduces complications and length of postoperative stay compared to the conventional (CON) protocol. However, stress and pain responses have not been compared between the two protocols. OBJECTIVES: To compare stress, pain, and related neuropeptidic responses (adrenocorticotropic hormone [ACTH], cortisol, and neuropeptide Y [NPY]) between FT and CON protocols. METHOD: A clinical trial with repeated measurements was conducted (May 2012 to May 2014) with a sample of 63 hepatectomized or pancreatectomized patients randomized into two groups: FT ( n = 29) or CON ( n = 34). Demographic and clinical data were collected, and pain (Visual Analog Scale [VAS] and Behavioral Pain Scale [BPS]) and stress responses (3 self-report questions) assessed. NPY, ACTH, and cortisol plasma levels were measured at T1 = day of admission, T2 = day of surgery, and T3 = prior to discharge. RESULTS: ACTHT1 and ACTHT2 levels were positively correlated with self-reported stress levels (ρ = .43 and ρ = .45, respectively, p < .05) in the FT group. NPY levels in the FT group were higher than those in the CON group at all time points ( p ≤ .004); this difference remained significant after adjusting for T1 levels through analysis of covariance for age, gender, and body mass index ( F = .003, F = .149, F = .015, respectively, p > .05). CONCLUSIONS: Neuropeptidic levels were higher in the FT group. Future research should evaluate this association further, as these biomarkers might serve as objective indicators of postoperative pain and stress.

Left-sided gallbladder (Sinistroposition) encountered during laparoscopic cholecystectomy: A rare case report and review of the literature.

INTRODUCTION: True Left-sided gallbladder (LSG) is a rare anatomical variation with a prevalence of 0.3%. Mainly discovered during the operation, its surgical approach in the laparoscopic setting may be challenging even for an experienced surgeon. PRESENTATION OF CASE: LSG was unexpectedly discovered in a young man during laparoscopic cholecystectomy. There were no pre-operative indications of this sinistroposition. The laparoscopic cholecystectomy was performed with minor surgical modifications and it was uneventful. A meticulous review of recent literature about LSGs was conducted as well. DISCUSSION: LSG is a scarce anatomical aberration that is difficultly identified pre-operatively. Surgeons should be aware of this aberration and of its accompanying anatomical variations in order to perform a safe laparoscopic cholecystectomy. CONCLUSION: Surgeons, by placing the patient to left-side up position, are able to expose the Calot's triangle and possible accompanying anatomical anomalies and thus perform a safe laparoscopic cholecystectomy without difficult surgical modifications.

Development and psychometric evaluation of an instrument for the assessment of nurses' knowledge on capnography.

BACKGROUND: Despite the expansion of capnography use, instruments for evaluating healthcare professionals' knowledge about capnography are missing from international literature. OBJECTIVES: To develop and validate an instrument for evaluating nurses' knowledge about capnography, named the "Nurses' Knowledge about Capnography Test" (NKCT). METHOD: A literature review was performed to formulate instrument items. Thirty-six items were initially developed, which covered principles of capnography function, conditions affecting end-tidal CO2 pressure and capnography waveform, and indications for capnography use. Six items were deleted after content validity and intra-rater reliability evaluation. The final 30-item instrument was completed by 103 anesthesiology department nurses employed in six hospitals of Greece, to test its internal consistency, item difficulty and discrimination, and construct validity. RESULTS: Kuder-Richardson 20 coefficient was 0.79. Ten items were found to be of high difficulty, while item discrimination was low for two of them. Instrument scores were found significantly higher among participants with higher educational level and longer experience in capnography use. CONCLUSION: NKCT is a psychometrically comprehensive instrument for evaluating nurses' knowledge about capnography, which is recommended to be re-validated beyond the anesthesiology department and be used for the assessment of educational programs on capnography.

Perioperative Adverse Respiratory Events in Overweight/Obese Children: Systematic Review.

Childhood obesity is associated with numerous respiratory disorders, which may be aggravated when general anesthesia is administered. This systematic review aimed to investigate and synthesize the published literature on the associations between childhood obesity and perioperative adverse respiratory events (PAREs). By using key terms, observational studies published between 1990 and 2014 in English-language journals indexed by Cumulative Index for Nursing and Allied Health Literature, PubMed, Web of Science, Cochrane Database, and EMBASE were searched for reports of relevant associations. Nine articles were considered eligible for inclusion. In all studies, significant univariate and multivariate associations were reported between obesity and increased risk for PAREs in pediatric patients, mainly for hypoxemia, upper airway obstruction, and difficult mask ventilation. Appropriate strategies for preventing PAREs in obese children need to be followed by health care professionals. Multicenter studies are also recommended for ensuring high generalizability of reported associations and elucidating underlying mechanisms that link obesity to PAREs.
