Pain Predictors in Patients in the Postanesthesia Care Unit.

PURPOSE: To analyze the effects of pain-predicting factors on patients in the postanesthesia care unit (PACU). DESIGN: This is an observational and prospective study. METHODS: This study was conducted at a University Hospital in the state of Minas Gerais (Brazil). To collect data on demographic, clinical, and surgical factors, a collection instrument was devised. The verbal numerical scale was employed to measure pain levels before and after surgery in the PACU. A path analysis was used to assess a predictive model. FINDINGS: A total of 226 patients were included in this study. The incidence of pain in the PACU was 31.9%. A model with demographic, clinical, and surgical variables was tested. The final model, after including modification indices, obtained results that indicated an acceptable data fit (comparative fit index = 0.996; root mean square error of approximation = 0.08). Age (being young), sex (being a woman), oncological diagnosis as an indication for the surgical procedure, type of surgery (surgery of the digestive system), duration of surgery (longer surgeries), and high intraoperative doses of opioids were predictive variables for pain in the PACU. CONCLUSIONS: This study's findings provide support for pain management in the PACU. Furthermore, the results of this research can be used to anticipate the occurrence of acute postoperative pain and personalized perioperative analgesia needs.

Sugammadex Reduces PACU Recovery Time after Abdominal Surgery Compared with Neostigmine.

OBJECTIVE: This study blindly evaluated sugammadex compared with neostigmine on length of stay in the postanesthesia care unit (PACU). METHODS: Fifty patients undergoing elective laparoscopic cholecystectomy or abdominal wall hernia repair consented to receive either sugammadex (2 mg/kg) or neostigmine (0.07 mg/kg) for the reversal of rocuronium neuromuscular blockade. Reversal agents were administered during surgical closing, and the train of four was measured until a twitch ratio of T4:T1 ≥ 0.9 was obtained to signify a robust reversal. Postreversal outcomes also were measured during PACU stay. Aldrete scores, pain visual analog scale score, and nausea were measured during the PACU stay. RESULTS: Patients receiving sugammadex experienced a shorter PACU stay at the time of discharge than patients receiving neostigmine, by an average of 12 minutes (P < 0.05). CONCLUSIONS: Sugammadex patients had a significantly shorter PACU stay.

Adult cardiac surgery during COVID-19 lockdown: Impact on activity and outcomes in a high-volume centre.

BACKGROUND: The coronavirus disease 2019 (COVID-19) outbreak had a direct impact on adult cardiac surgery activity, which systematically necessitates a postoperative stay in intensive care. AIM: To study the effect of the COVID-19 lockdown on cardiac surgery activity and outcomes, by making a comparison with the corresponding period in 2019. METHODS: This prospective observational cohort study compared adult cardiac surgery activity in our high-volume referral university hospital from 9 March to 10 May 2020 versus 9 March to 10 May 2019. Data were collected in our local certified database and a national database sponsored by the French society of thoracic and cardiovascular surgery. The primary study endpoints were operative mortality and postoperative complications. RESULTS: With 105 interventions in 2020, our activity dropped by 57% compared with the same period in 2019. Patients were at higher risk, with a significantly higher EuroSCORE II score (3.8±4.5% vs. 2.0±1.8%; P<0.001) and higher rates of active endocarditis (7.6% vs. 2.9%; P=0.047) and recent myocardial infarction (9.5% vs. 0%; P<0.001). The weight and priority of the interventions were significantly different in 2020 (P=0.019 and P<0.001, respectively). The rate of acute aortic syndromes was also significantly higher in 2020 (P<0.001). Operative mortality was higher during the lockdown period (5.7% vs. 1.7%; P=0.038). The postoperative course was more complicated in 2020, with more postoperative bleeding (P=0.003), mechanical circulatory support (P=0.032) and prolonged mechanical ventilation (P=0.005). Only two patients (1.8%) developed a positive status for severe acute respiratory syndrome coronavirus 2 after discharge. CONCLUSIONS: Adult cardiac surgery was heavily affected by the COVID-19 lockdown. A further modulation plan is necessary to improve outcomes and reduce postponed operations to decrease operative mortality and morbidity.

ANTECEDENTES: las guías de práctica clínica vigentes recomiendan el empleo de escalas objetivas como criterio de alta postendoscopia con sedación. OBJETIVO: valorar el tiempo de recuperación, las complicaciones y el grado de satisfacción del paciente empleando la escala mPADSS. MATERIAL Y MÉTODOS: se recogieron datos demográficos y antecedentes médicos. Se midieron constantes vitales, ansiedad y dolor abdominal preendoscopia. Se aleatorizó a los pacientes, que fueron divididos en grupo control, el cual recibió el alta según la práctica habitual, y grupo intervención, al cual se le pasó la escala mPADSS cada diez minutos, hasta alcanzar una puntuación objetivo. RESULTADOS: fueron aleatorizados 118 pacientes (78 colonoscopias, 32 gastroscopias, tres gastro + colonoscopia y 15 colangiopancreatografía retrógrada endoscópica/ultrasonografía endoscópica [CPRE/USE]). Como antecedentes médicos, 36 pacientes presentaron hipertensión arterial (HTA) y 19, diabetes mellitus (DM); 15 tenían medicación anticoagulante/antiagregante y 21, hipnótica/ansiolítica. Se requirió una media de 160 mg de propofol por paciente y se emplearon también flumazenilo y midazolam en 49 pacientes. Se registraron dos episodios de vómitos y tres de desaturación leves, todos ellos en grupo control. Incluimos 60 pacientes en grupo control y 58 en grupo mPADSS, los cuales recibieron el alta en 15 y 10 minutos de media respectivamente (p < 0,005). Se dispone de datos de seguimiento telefónico las 24-48 h de 105 sujetos. Se registraron cuatro reingresos (tres control y uno mPADSS). No hubo diferencias en cuanto a dolor y síntomas postsedación. El grado de satisfacción en cuanto a la atención y al tiempo de estancia fue similar en ambos grupos. CONCLUSIONES: este trabajo muestra la eficiencia, seguridad y satisfacción del paciente ante el empleo de la escala mPADSS, por lo que puede recomendarse su empleo

Very early postoperative troponin increase and clinical outcome in patients admitted to the recovery room after noncardiac surgery with suspected cardiac events.

We assessed the prognostic meaning of very early (<6 h) troponin increase after noncardiac surgery in a population of patients admitted to the recovery room, for whom troponin measurements were taken because of a suspected cardiac event. Among a total of 296 patients, abnormal troponin was found in 24 (8.1%). Ten patients in this group (41.7%) and 27 among those with normal troponin (9.9%) experienced cardiovascular death, myocardial infarction, or decompensated heart failure at one month (p < 0.0001). Troponin was independently associated with a two-fold risk of events (p < 0.0001). In these patients, very early troponin measurement in the recovery room may help to identify patients at risk of cardiovascular events.

Remifentanil for abdominal surgery is associated with unexpectedly unfavorable outcomes.

Insufficient perioperative pain treatment is known as a highly predictive risk factor for the development of chronic postoperative pain. Remifentanil is an ultrashort-acting opioid that provides quick and efficient analgesia but is associated with the induction of opioid-induced hyperalgesia. Despite these well-known characteristics, this substance is being increasingly used in anesthesia and in a variety of medical fields, such as intensive-care medicine and obstetrics. The aim of our study was to reveal whether remifentanil influences postoperative pain, the requirement for postoperative analgesics, and requirement of antiemetics (as indirect indicator of postoperative nausea and vomiting), as well as the effects on time to extubation and length of stay in the postanesthesia care unit in daily clinical routine. From an electronic medical records database of 55,693 anesthesias, we analyzed data from all patients receiving intraabdominal surgery (visceral, gynecological, and urological) under general anesthesia or combined general-epidural anesthesia by propensity score matching. The administration of remifentanil was associated with higher postoperative pain scores despite a higher requirement of postoperative analgesics. Additional epidural analgesia was not able to avoid this finding. The intraoperative use of remifentanil is associated with a deterioration of pain levels and postoperative analgesic requirement, wherefore the potential benefit of this substance seems to be outweighed by its potential disadvantages. Especially in operative procedures in which high postoperative pain scores are expected, the unreflective use should be critically questioned.

The Effects of Music on the Life Signs of Patients in the Reanimation Unit/Recovery Room After Laparoscopic Cholecystectomy.

The purpose of the study is to determine the effects of music on the life signs of patients in the postanesthesia care unit after laparoscopic surgery. The study was carried out as a quasi-experimental model with pretest-posttest and control group in the postanesthesia care unit of a training and education hospital from March 2017 to May 2018. The sample consisted of 148 patients (74 experiment and 74 control) who were selected by the method of nonprobability sampling determined on the basis of power analysis who met the inclusion criteria. When the change in the life signs between the groups was examined, after music treatment (second measurement), there was a significant difference only in the respiratory rates (P < .05). There was a significant difference in terms of diastolic blood pressures and respiratory rates in the first admission to the clinic from the postanesthesia care unit (third measurement) (P < .05).

The ratio of PACU length-of-stay to surgical duration: Practical observations.

BACKGROUND: Operating room (OR) and post-anesthesia care unit (PACU) activity are closely linked since the number, type, and sequence of surgeries influence subsequent PACU activity. We aimed to explore the relationship between duration-of-surgery (DOS) and PACU length-of-stay (LOS), the PACU-LOS:DOS ratio, since it is among the determinants of the number of PACU beds and nurse staffing required to insure efficient egress of patients from the OR. METHODS: PACU-LOS:DOS ratio was examined using retrospective data from a tertiary medical center's surgical information system (Phase 1) and prospectively collected data from a convenience sample of post-operative patients (Phase 2). RESULTS: Phase 1 included 17 047 patients, the majority (73%) with PACU-LOS:DOS ratios >1.0, indicating PACU-LOS longer than DOS. Median PACU-LOS was 117 minutes, median DOS was 80 minutes, and median PACU-LOS/DOS ratio was 1.5. PACU-LOS showed greater variability than DOS because of extended PACU stays. Phase 2 (n = 2054) confirmed Phase 1 results (median PACU-LOS/DOS ratio - 1.8). In both phases at a DOS of >130 minutes PACU-LOS/DOS ratio became <1.0. In 24% of Phase 2 patients PACU-LOS was prolonged because of administrative issues. Post-operative, more than pre- and intra-operative, measurements influenced PACU-LOS. CONCLUSIONS: The PACU-LOS/DOS ratio proved useful for demonstrating interactions between 2 central components of the surgical system. The many patients with PACU-LOS:DOS ratios >1.0 provides objective evidence for the number of PACU beds exceeding the number of ORs.

The Utility and Cost Effectiveness of Immediate Postoperative Laboratory Studies in Hip and Knee Arthroplasty.

BACKGROUND: Routine immediate postoperative laboratory studies, including metabolic panels and hematologic profiles, are commonly ordered after arthroplasty procedures. However, their values only occasionally influence management. This study investigated the clinical utility and value of these tests. METHODS: A large retrospective cohort study of 18,935 patients spanning a 6-year period from 2008 to 2013 from a single high-volume institution was evaluated. Only immediate postoperative labs drawn on postoperative day 0 in the recovery room were included in the study. Complete blood counts (CBC) and basic metabolic panels (BMP) were reviewed, and ranges of abnormal were set for each lab test based on values significant enough to impact patient management. Cost effectiveness calculations were made based on current cost of the laboratory tests. RESULTS: Actionably low hemoglobin values ( < 8 g/dL) were found in 1.44% of the overall cohort. Unilateral primary total knee arthroplasty was associated with the fewest hemoglobin abnormalities at 0.59%. Primary unilateral total hip arthroplasty was associated with abnormal hemoglobin values in 1.81% of cases. Significant electrolyte abnormalities were far less common, with hyperkalemia (> 6.5 mEq/L) in 0.19%, hyponatremia ( < 120 mEq/L) in 0.01% and elevated creatinine (> 2.0 mg/dL) was found in 0.25%. Hemoglobin values were calculated at a cost of $1,710 to detect a single significantly abnormal result. The cost to detect a single actionably abnormal BMP value was $1,000. CONCLUSIONS: Routine immediate postoperative laboratory tests represent a high institutional cost and are seldom abnormal enough to warrant a change in patient management. The routine use of these tests can likely be safely eliminated in uncomplicated primary unilateral arthroplasty procedures.

Effect of postoperative partial bladder filling after minimally invasive hysterectomy on postanesthesia care unit discharge and cost: a single-blinded, randomized controlled trial.

BACKGROUND: Hysterectomy is one of the most common surgical procedures performed each year with substantial related health care costs. This trial studied the effect of postoperative bladder backfilling to submicturition level in the operating room and its effect on early postoperative patient care and related cost. OBJECTIVE: The objective of the study was to compare the effect of bladder backfilling on early postoperative patient care and related cost. STUDY DESIGN: This was a randomized, single-blinded, controlled trial conducted between April 2016 and February 2017 at a single urban university hospital providing tertiary care for minimally invasive gynecologic surgery. Ninety-one patients undergoing straight-stick laparoscopic and robot-assisted hysterectomy by minimally invasive gynecologic surgeons for benign indications were recruited. The bladder was partially backfilled with 150 mL of normal saline postoperatively in the intervention group and drained in the control group, as per standard of care. Main outcomes studied were time needed to void, time spent in the postanesthesia care unit, and postanesthesia care unit cost after minimally invasive hysterectomy. Our secondary outcomes were postoperative complications. RESULTS: Forty-six patients (50.5%) were randomized to the intervention group, and 45 patients (49.5%) to the control group. Baseline comparative analysis of demographics and preoperative patient-specific variables, surgical history, intraoperative characteristics, and administered medications found the 2 groups to be largely homogenous. After regression analyses for adjustment, we found a significant reduction in the time needed to void, time spent in the postanesthesia care unit, and postanesthesia care unit-associated cost in the intervention group. Patients voided 64.9 minutes earlier than the control group (P = .015) ans spent 64 fewer minutes in the postanesthesia care unit (P = .006), resulting in $401.5 (USD) saving per patient (P = .006). None of the patients encountered any postoperative complications. CONCLUSION: Based on the findings of this randomized clinical trial, postoperative bladder backfilling to submicturition level shortens the time needed for patients to void in the postanesthesia care unit, resulting in shorter postanesthesia care unit stay and resultant cost savings. Conservatively projecting our findings on minimally invasive hysterectomy procedure is estimated to result in $69 million to $139 million (USD) per year in savings. Initiating similar investigations in other ambulatory surgical fields will likely result in a more substantial impact.

Are Postoperative Clinical Outcomes Influenced by Length of Stay in the Postanesthesia Care Unit?

PURPOSE: To compare clinical outcomes of patients who required a prolonged length of stay in the postanesthesia care unit (PACU) with a control group. DESIGN: A single-center purposive-sampled retrospective medical record and database audit. METHODS: Patients with prolonged PACU stays were compared to a group of patients whose stay was less than median for outcome measures: rapid response team (RRT) activation, cardiac arrest, unanticipated intensive care unit admissions, and survival to discharge. FINDINGS: A total of 1,867 patients were included in the analysis (n = 931 prolonged stay and n = 933 control group). Prolonged stay in PACU was higher among patients who were older, had higher American Society of Anesthesiologist score, and were discharged to wards during the afternoon or late nursing shift. RRT activation after discharge from PACU occurred in more patients in the study group compared with the control group (7% vs 1%, respectively). There were no cardiac arrests recorded in either group within the 24 hours after PACU discharge period. CONCLUSIONS: Prolonged stay in the PACU for 2 or more hours because of clinical reasons appears to be associated with a higher incidence of clinical deterioration in the ward setting requiring RRT intervention within 24 hours after discharge from PACU.

Time to recovery after general anesthesia at hospitals with and without a phase I post-anesthesia care unit: a historical cohort study.

PURPOSE: There is little knowledge about how hospitals can best handle disruptions that reduce post-anesthesia care unit (PACU) capacity. Few hospitals in Japan have any PACU beds and instead have the anesthesiologists recover their patients in the operating room. We compared postoperative recovery times between a hospital with (University of Iowa) and without (Shin-yurigaoka General Hospital) a PACU. METHODS: This historical cohort study included 16 successive patients undergoing laparoscopic gynecologic surgery with endotracheal intubation for general anesthesia, at each of the hospitals, and with the hours from OR entrance until the last surgical dressing applied ≥ two hours. Postoperative recovery times, defined as the end of surgery until leaving for the surgical ward, were compared between the hospitals. RESULTS: The median [interquartile range] of recovery times was 112 [94-140] min at the University of Iowa and 22 [18-29] min at the Shin-yurigaoka General Hospital. Every studied patient at the University of Iowa had a longer recovery time than every such patient at Shin-yurigaoka General Hospital (Wilcoxon-Mann-Whitney, P < 0.001). The ratio of the mean recovery times was 4.90 (95% confidence interval [CI], 4.05 to 5.91; P < 0.001) and remained comparable after controlling for surgical duration (5.33; 95% CI, 3.66 to 7.76; P < 0.001). The anesthetics used in the Iowa hospital were a volatile agent, hydromorphone, ketorolac, and neostigmine compared with the Japanese hospital where bispectral index monitoring and target-controlled infusions of propofol, remifentanil, acetaminophen, and sugammadex were used. CONCLUSIONS: This knowledge can be generally applied in situations at hospitals with regular PACU use when there are such large disruptions to PACU capacity that it is known before a case begins that the anesthesiologist likely will need to recover the patient (i.e., when there will not be an available PACU bed and/or nurse). The Japanese anesthesiologists have no PACU labour costs but likely greater anesthesia drug/monitor costs.

Nonclinical Factors Affecting PACU Discharge: A Clinical Audit in a One-Day Surgery Unit.

PURPOSE: To determine the nonclinical causes of delayed discharge from the postanesthesia care unit (PACU). DESIGN: A prospective observational study. METHODS: Over a 2-month period, data were collected on 576 patients who were transferred to the clinical areas from PACU after surgery. Patients were considered ready for discharge after they had achieved a satisfactory discharge score. FINDINGS: The most common documented reason for nonclinical delayed discharge was lack of available transport (45.5%; n = 310) followed by bed availability (13%; n = 89) and the receiving registered nurse's readiness to accept a transfer from PACU (7.3%; n = 50). CONCLUSIONS: Nonclinical delays account for a considerable extension of a patient's time in PACU. The findings of this study suggest that understanding and addressing the causes of delayed discharge in PACU may help to improve patient flow and reduce discharge times. Future research should include the cost associated with these delays and assess the effectiveness of interventions introduced to eliminate such delays.

Comparison of a novel clinical score to estimate the risk of REsidual neuromuscular block Prediction Score and the last train-of-four count documented in the electronic anaesthesia record: A retrospective cohort study of electronic data on file.

BACKGROUND: Residual neuromuscular block (rNMB) after surgery is not difficult to identify if proper neuromuscular monitoring is used, but many clinicians do not use quantitative neuromuscular monitoring. OBJECTIVE: The aim of this study was to develop a REsidual neuromuscular block Prediction Score (REPS) to predict postoperative rNMB and compare the predictive accuracy of the prediction score with train-of-four count (TOFC) measurement at the end of a surgical case. DESIGN: Retrospective cohort study of data on file. DATA SOURCE: Electronic patient data and peri-operative data on vital signs, administered medications, and train-of-four ratio (TOFR) obtained in the postoperative recovery rooms [postanaesthesia care unit (PACU)] at Massachusetts General Hospital in Boston, Massachusetts, USA. PATIENTS: Quantitative TOFR measurements obtained on admission to the PACU were available from 2144 adult noncardiac surgical patients. MAIN OUTCOME MEASURE: Presence of rNMB at PACU admission, defined as a TOFR of less than 0.9. RESULTS: In the score development cohort (n=2144), rNMB occurred in 432 cases (20.2%). Ten independent predictors for residual paralysis were identified and used for the score development. The final model included: hepatic failure, neurological disease, high-neostigmine dose, metastatic tumour, female sex, short time between neuromuscular blocking agent administration and extubation, aminosteroidal neuromuscular blocking agent, BMI more than 35, absence of nurse anaesthetist and having an experienced surgeon. The model discrimination by C statistics was 0.63, 95% confidence interval (0.60 to 0.66), and risk categories derived from the REPS had a higher accuracy than the last documented intra-operative TOFC for predicting rNMB (net reclassification improvement score 0.26, standard error 0.03, P < 0.001). CONCLUSION: The REPS can be used to identify patients at greater risk of rNMB. This tool may inform anaesthetists better than an intra-operative TOFC and thus enable peri-operative anaesthetic practices to be tailored to the patient and minimise the undesirable effects of rNMB. TRIAL REGISTRY NUMBER: Approved by Partners Human Research Committee (protocol number 2016P000940) at MGH in Boston, Massachusetts, USA on 25 April 2016.

Analysis of adverse outcomes in the post-anesthesia care unit based on anesthesia liability data.

STUDY OBJECTIVE: The aim of this study is to provide a contemporary medicolegal analysis of claims brought against anesthesiologists in the United States for events occurring in the post-anesthesia care unit (PACU). DESIGN: In this retrospective analysis, we analyzed closed claims data from the Controlled Risk Insurance Company (CRICO) Comparative Benchmarking System (CBS) database. SETTING: Claims closed between January 1, 2010 and December 31, 2014 were included for analysis if the alleged damaging event occurred in a PACU and anesthesiology was named as the primary responsible service. PATIENTS: Forty-three claims were included for analysis. Data regarding ASA physical status and comorbidities were obtained, whenever available. Ages ranged from 18 to 94. Patients underwent a variety of surgical procedures. Severity of adverse outcomes ranged from temporary minor impairment to death. INTERVENTIONS: Patients receiving care in the PACU. MEASUREMENTS: Information gathered for this study includes patient demographic data, alleged injury type and severity, operating surgical specialty, contributing factors to the alleged damaging event, and case outcome. Some of these data were drawn directly from coded variables in the CRICO CBS database, and some were gathered by the authors from narrative case summaries. RESULTS: Settlement payments were made in 48.8% of claims. A greater proportion of claims involving death resulted in payment compared to cases involving other types of injury (69% vs 37%, p = 0.04). Respiratory injuries (32.6% of cases), nerve injuries (16.3%), and airway injuries (11.6%) were common. Missed or delayed diagnoses in the PACU were cited as contributing factors in 56.3% of cases resulting in the death of a patient. Of all claims in this series, 48.8% involved orthopedic surgery. CONCLUSIONS: The immediate post-operative period entails significant risk for serious complications, particularly respiratory injury and complications of airway management. Appropriate monitoring of patients by responsible providers in the PACU is crucial to timely diagnosis of potentially severe complications, as missed and delayed diagnoses were a factor in a number of the cases reviewed.

Outpatient curettage and electrocautery as an alternative to primary surgical closure for pediatric gastrocutaneous fistulae.

BACKGROUND: The development of a gastrocutaneous fistula (GCF) after gastrostomy tube removal is a frequent complication that occurs 5%-45% of the time. Conservative therapy with chemical cauterization is frequently unsuccessful, and surgical GCF repair with open primary layered closure of the gastrotomy is often required. We describe an alternative approach of GCF closure that is an outpatient, less invasive procedure that allows patients to avoid the comorbidities of general endotracheal anesthesia and intraabdominal surgery. METHODS: This is an Institutional Review Board approved retrospective review of all patients who underwent GCF closure from January 2010 to July 2016 at a tertiary care children's hospital. Demographics including age, weight, body mass index, comorbidities, and initial indication for gastrostomy tube were recorded. Operative details such as ASA score, operative duration, type of anesthesia, and airway were noted. Based on surgeon preference, two types of operative closure were used during that time frame: primary layered closure or curettage and cautery (C&C). The latter is a procedure in which the fistula tract is first scraped with a fine curette, and then the fistula opening and tract are cauterized circumferentially. Finally, the presence of a persistent fistula and the need for formal reoperation were determined. RESULTS: Sixty-five unique patients requiring GCF closure were identified. Of those, 44 patients (67.6%) underwent primary closure and 21 patients (32.3%) underwent C&C. The success rate of primary closure was 97% with one patient experiencing wound breakdown with persistent fistula. The overall success rate of C&C was 66.7% (14/21). Among those 14 patients, 11 (52.4%) GCF patients were closed by 1 mo. An additional two patients' gastrocutaneous fistulae were closed by 4 mo (61.9%). One GCF was successfully closed with a second C&C procedure. Seven of the 21 patients (33.3%) required subsequent formal layered surgical closure. C&C had significantly shorter operative times (13.5 ± 14.7 min versus 93.4 ± 61.8, P <0.0001) and significantly shorter times in the postanesthesia care unit (101.8 ± 42.4 min versus 147 ± 86, P <0.0001). Patients were intubated with an endotracheal tube 88.6% of the time for primary closure and 23.8% of the time for C&C.Among patients admitted for an elective procedure, the average length of stay for primary closure was 1.9 d as compared to 0 d for the C&C group. Among patients who underwent C&C with a persistent fistula, there were no significant differences in time since initial creation of gastrostomy, age, body mass index, or ASA score. CONCLUSIONS: Our study verifies that primary closure remains the gold standard for persistent GCF. However, C&C is a safe, outpatient procedure that effectively treats a GCF the majority of the time in children. We suggest that in select patients, it may be an appropriate initial and definitive procedure for GCF closure.

Low anaesthetic waste gas concentrations in postanaesthesia care unit: A prospective observational study.

BACKGROUND: Volatile anaesthetics are a potential hazard during occupational exposure, pregnancy or in individuals with existing disposition to malignant hyperthermia. Anaesthetic waste gas concentration in postanaesthesia care units (PACU) has rarely been investigated. OBJECTIVE(S): The current study aims to assess concentrations of volatile anaesthetics in relation to room size, number of patients and ventilator settings in different PACUs. DESIGN: A prospective observational study. SETTING: Two different PACUs of the Hannover Medical School (Hannover, Germany) were evaluated in this study. The rooms differed in dimensions, patient numbers and room ventilation settings. PATIENTS: During the observation period, sevoflurane anaesthesia was performed in 65 of 140 patients monitored in postanaesthesia unit one and in 42 of 70 patients monitored in postanaesthesia unit two. MAIN OUTCOME MEASURES: Absolute trace gas room concentrations of sevoflurane measured with a compact, closed gas loop high-resolution ion mobility spectrometer. RESULTS: Traces of sevoflurane could be detected in 805 out of 970 samples. Maximum concentrations were 0.96 ±â€Š0.20 ppm in postanaesthesia unit one, 0.82 ±â€Š0.07 ppm in postanaesthesia unit two. Median concentration was 0.12 (0.34) ppm in postanaesthesia unit one and 0.11 (0.28) ppm in postanaesthesia unit two. CONCLUSION: Low trace amounts of sevoflurane were detected in both PACUs equipped with controlled air exchange systems. Occupational exposure limits were not exceeded.

Operation and organisation of ambulatory surgery in France. Results of a nationwide survey; The OPERA study.

Operation and organisation of ambulatory surgical activity in France remains largely undocumented. This nationwide observational prospective survey, carried out between December 2013 and December 2014, was undertaken to characterise the organisational processes of ambulatory surgery in France. Three hundred centres were randomly chosen from a list of 891 hospitals practicing ambulatory surgery, with stratification according to the type of facility (public general hospital, university hospital, private hospital) and region. An email was sent to the board of the randomly chosen facilities with an attached information letter explaining how the survey worked. Hospitals who did not reply to this email were contacted by phone. Among the 206 hospitals that answered the survey, 92 were private, 78 were public and 36 were university hospitals. Median accommodation capacities of ambulatory units were 8 beds, mostly distinct from conventional surgical ward. Patient pathways dedicated to ambulatory surgery appear as the current predominant practice. 77% of the French ambulatory units have a head nurse in charge of logistics and coordination. Several items still have to be improved, such as the adherence to modern fasting rules and the unnecessary use of stretcher to move the patient. Objective discharge score is used in 77% of ambulatory units. This survey highlights the implementation of some positive organisational parameters corresponding to common good practices recommendations. In contrast, several other recommendations are still insufficiently applied and may hamper the development of safe ambulatory surgery. This brings up new challenges for health regulatory boards, hospitals and ambulatory units managers.

Two techniques for assessing postoperative voiding function, a randomized trial.

INTRODUCTION AND HYPOTHESIS: Post-operative voiding dysfunction is common after sling placement and is assessed with a voiding trial (VT) before discharge. We hypothesized that an operating room (OR) initiated retrograde VT (OR-fill) would decrease time to discharge compared with a post-anesthesia care unit (PACU) initiated retrograde VT (PACU-fill). METHODS: This was a parallel non-blinded randomized trial, of women undergoing outpatient sling surgery at a university hospital. In the OR-fill group, fill was initiated after sling placement during cystoscopy by leaving fluid in the bladder. In the PACU-fill group, fill was initiated in the PACU. Pre-VT volumes were recorded and a PVR ≤ 100 mL defined a passed VT. The primary outcome was total PACU time, defined as arrival in PACU until discharge home. RESULTS: Thirty women were assigned to the OR-fill group and 29 to the PACU-fill group. Time from PACU arrival to VT was shorter in the OR-fill group (41.5 [31.0, 69.3] min vs 69.0 [44.0, 107.0] min, p = 0.03), but total PACU time in the groups was similar (125.0 [90.5, 180.5] min vs 131.5 [93.5, 178.0] min, p = 0.76). Bladder volume before VT was greater in the OR-fill group (557.3 ± 187.3 mL vs 433.0 ± 171.2 mL, p = 0.01). VT pass rates of the two groups were not significantly different (OR-fill 16.7% vs PACU-fill 24.1%, p = 0.48). CONCLUSIONS: OR-fill VT did not decrease total PACU time compared with PACU-fill VT. No overdistension was seen in either group; transient postoperative voiding dysfunction was common.
