[Short version of recommendations for enhanced recovery program (ERP) for cystectomy: Technical measures]. / Version courte des recommandations de la récupération ameliorée après chirurgie (RAAC) pour la cystectomie : mesures techniques.

INTRODUCTION: The enhanced recovery program (ERP) is a management mode whose objective is to reduce the risk of complications and allow the patient to recover more quickly all its functional capacities and to reintegrate at most quickly and safely in his usual environment. This intentionally synthetic document aims to disseminate in the urological community the main points of the ERP recommendations for cystectomy. This work, coordinated by AFU, involves several other partners. The full document is available on the "Urofrance" website. Another article will follow on organizational measures. METHOD: The development of the recommendations is based on the method "formalized consensus of experts" proposed by the HAS. The report is based on a systematic review of the literature (January 2006-May 2017), two rounds of iterative quotations and a national proofreading. Levels of proof of conclusions and gradation of recommendations are based on the HAS grid. RESULTS: The bibliographic strategy made it possible to retain 298 articles. Only the recommendations that obtained a strong agreement after the two rounds of iterative listing were retained. The recommendations presented here are in chronological form (before, during, after hospitalization). Twenty-six key points on the technical and organizational measures of ERP have been identified. CONCLUSION: The result of the literature review, supplemented by expert opinion, suggests a significant clinical interest in the application and dissemination of ERP for cystectomy, despite the limited data available for this indication.

Ropivacaine preperitoneal wound infusion for pain relief and prevention of incisional hyperalgesia after laparoscopic colorectal surgery: a randomized, triple-arm, double-blind controlled evaluation vs intravenous lidocaine infusion, the CATCH study.

AIM: The abdominal incision for specimen extraction could trigger postoperative pain after laparoscopic colorectal resections (LCRs). Continuous wound infusion (CWI) of ropivacaine may be a valuable option for postoperative analgesia. This study was undertaken to evaluate the potential benefits of ropivacaine CWI on pain relief, metabolic stress reaction, prevention of wound hyperalgesia and residual incisional pain after LCR. A subgroup with intravenous lidocaine infusion (IVL) was added to discriminate between the peripheral and systemic effects of local anaesthetic infusions. METHOD: Patients were randomly allocated to three subgroups: CWI (0.2% ropivacaine 10 ml/h for 48 h); IVL (lidocaine 1.5% at 4 ml/h for 48 h); control group. RESULTS: In all, 95 patients were randomized (86 patients analysed). Postoperative pain intensity did not differ significantly between groups. Within the first 24 h after surgery, morphine requirement was significantly lower in the CWI group compared with the IVL group, but there was no significant difference compared with the control group (P = 0.02 and P = 0.15, respectively). The area of hyperalgesia did not differ significantly between subgroups, nor did the hyperalgesia ratio which was 1.2 cm (0.0-6.7) vs 1.9 cm (0.4-4.0) vs 2.0 cm (0.5-7.0) in the CWI, IVL and control groups respectively (P = 0.35). The number of patients reporting residual incisional pain after 3 months (3/26 vs 4/23 vs 4/23 in the CWI, IVL and control groups respectively) did not differ significantly between the groups, nor did their metabolic stress reactions. CONCLUSION: Ropivacaine CWI at the site of the abdominal incision did not provide any significant benefit either on analgesia or on the prevention of wound hyperalgesia after LCR.

Cost-effectiveness analysis comparing epidural, patient-controlled intravenous morphine, and continuous wound infiltration for postoperative pain management after open abdominal surgery.

BACKGROUND: Continuous wound infiltration (CWI), i.v. patient-controlled analgesia (i.v.-PCA), and epidural analgesia (EDA) are analgesic techniques commonly used for pain relief after open abdominal surgery. The aim of this study was to evaluate the cost-effectiveness of these techniques. METHODS: A decision analytic model was developed, including values retrieved from clinical trials and from an observational prospective cohort of 85 patients. Efficacy criteria were based on pain at rest (VAS ≤ 30/100 mm at 24 h). Resource use and costs were evaluated from medical record measurements and published data. Probabilistic sensitivity analysis (PSA) was performed. RESULTS: When taking into account all resources consumed, the CWI arm (€ 6460) is economically dominant when compared with i.v.-PCA (€ 7273) and EDA (€ 7500). The proportion of patients successfully controlled for their postoperative pain management are 77.4%, 53.9%, and 72.9% for CWI, i.v.-PCA, and EDA, respectively, demonstrating the CWI procedure to be both economically and clinically dominant. PSA reported that CWI remains cost saving in 70.4% of cases in comparison with EDA and in 59.2% of cases when compared with PCA. CONCLUSIONS: Device-related costs of using CWI for pain management after abdominal laparotomy are partly counterbalanced by a reduction in resource consumption. The cost-effectiveness analysis suggests that CWI is the dominant treatment strategy for managing postoperative pain (i.e. more effective and less costly) in comparison with i.v.-PCA. When compared with EDA, CWI is less costly with almost equivalent efficacy. This economic evaluation may be useful for clinicians to design algorithms for pain management after major abdominal surgery.

A multicentre observational study of intra-operative ventilatory management during general anaesthesia: tidal volumes and relation to body weight.

We conducted an observational prospective multicenter study to describe the practices of mechanical ventilation, to determine the incidence of use of large intra-operative tidal volumes (≥10 ml.kg(-1) of ideal body weight) and to identify patient factors associated with this practice. Of the 2960 patients studied in 97 anaesthesia units from 49 hospitals, volume controlled mode was the most commonly used (85%). The mean (SD) tidal volume was 533 (82) ml; 7.7 (1.3) ml.kg(-1) (actual weight) and 8.8 (1.4) ml.kg(-1) (ideal body weight)). The lungs of 381 (18%) patients were ventilated with a tidal volume>10 ml.kg(-1) ideal body weight. Being female (OR 5.58 (95% CI 4.20-7.43)) and by logistic regression, underweight (OR 0.06 (95% CI 0.01-0.45)), overweight (OR 1.98 (95% CI 1.49-2.65)), obese (OR 5.02 (95% CI 3.51-7.16)), severely obese (OR 10.12 (95% CI 5.79-17.68)) and morbidly obese (OR 14.49 (95% CI 6.99-30.03)) were the significant (p ≤ 0.005) independent factors for the use of large tidal volumes during anaesthesia.

Risk management in outpatient surgery.

Outpatient surgery has become a national policy priority set by health care authorities (targets for more than 70% of outpatient procedures by 2022), making ambulatory hospitalization the new standard of care. This practice introduces new risks along the patient's course. Even though these risks are low and although the literature and data from insurance databases is reassuring, the risks in outpatient surgery remain poorly understood. Risks can be organizational in view of the many stages of the patient journey that must be formalized-medical, anesthetic or surgical-in view of planned discharge the same evening as the procedure, and medico-legal because of the importance of the discharge authorization and the information provided to the patient. A risk management approach (a priori or a posteriori) has become a mandatory part of a policy of continuous quality improvement and safety of care. The coordination of all the team members (surgeon, anesthesiologist, nursing and administrative staff and the patient's accompanying person) as well as the patient's active participation are essential to minimize risks and prevent complications.

A systematic review of surgical site infections following day surgery: a frequentist and a Bayesian meta-analysis of prevalence.

BACKGROUND: Since 1990, several studies have focused on safety and patient satisfaction in connection with day surgery. However, to date, no meta-analysis has investigated the overall prevalence of surgical site infections (SSI). AIM: To estimate the overall prevalence of SSI following day surgery, regardless of the type of surgery. METHOD: A systematic review and a meta-analysis of the prevalence of SSI following day surgery, regardless of the type of surgery, was conducted, seeking all studies before June 2016. A pooled random effects model using the DerSimonian and Laird approach was used to estimate overall prevalence. A double arcsine transformation was used to stabilize the variance of proportions. After performing a sensitivity analysis to validate the robustness of the method, univariate and multi-variate meta-regressions were used to test the effect of date of publication, country of study, study population, type of specialty, contamination class, time of postoperative patient visit after day surgery, and duration of hospital care. FINDINGS: Ninety articles, both observational and randomized, were analysed. The estimated overall prevalence of SSI among patients who underwent day surgery was 1.36% (95% confidence interval 1.1-1.6), with a Bayesian probability between 1 and 2% of 96.5%. The date of publication was associated with the prevalence of SSI (coefficient -0.001, P = 0.04), and the specialty (digestive vs non-digestive surgery) tended to be associated with the prevalence of SSI (coefficient 0.03, P = 0.064). CONCLUSION: The meta-analysis showed a low prevalence of SSI following day surgery, regardless of the surgical procedure.

Meta-analysis of intravenous lidocaine and postoperative recovery after abdominal surgery.

BACKGROUND: Continuous intravenous administration of lidocaine may decrease the duration of ileus and pain after abdominal surgery. METHODS: Three databases (Medline, Embase and the Cochrane Controlled Trials Register) were searched to retrieve randomized controlled trials comparing continuous intravenous lidocaine infusion during and after abdominal surgery with placebo. Study design was scored using the Oxford Quality Score based on randomization, double-blinding and follow-up. Outcome measures were duration of ileus, length of hospital stay, postoperative pain, and incidence of nausea and vomiting. RESULTS: Eight trials were selected. A total of 161 patients received intravenous lidocaine, with 159 controls. Intravenous lidocaine administration decreased the duration of ileus (weighted mean difference (WMD) - 8.36 h; P < 0.001), length of hospital stay (WMD - 0.84 days; P = 0.002), postoperative pain intensity at 24 h after operation on a 0-100-mm visual analogue scale (WMD - 5.93 mm; P = 0.002), and the incidence of nausea and vomiting (odds ratio 0.39; P = 0.006). CONCLUSION: Continuous intravenous administration of lidocaine during and after abdominal surgery improves patient rehabilitation and shortens hospital stay.

Laparoscopic colon surgery: unreliability of end-tidal CO2 monitoring.

BACKGROUND: The relatively good haemodynamic and respiratory tolerance to abdominal CO(2) insufflation has mostly been observed in healthy patients during short-lasting laparoscopic procedures. End-tidal CO(2) pressure (PetCO(2)) has been shown to be a reliable method to assess arterial CO(2) (PaCO(2)) in the absence of cardio-respiratory disease in this setting. However, no study has investigated whether PetCO(2) is accurately related to PaCO(2) during laparoscopic colon surgery. Indeed, these procedures last longer, prolonging the pneumoperitoneum and requiring a Trendelenburg position. The aim of the present study was to measure the PaCO(2)-PetCO(2) difference over time in patients undergoing laparoscopic colon surgery and to determine whether PaCO(2) is reliably assessed by PetCO(2). METHODS: Forty consecutive patients (ASA I and II) scheduled for laparoscopic colon surgery were anaesthetized and ventilated to obtain a PetCO(2) between 4.0 and 5.5 kPa. After initiation of CO(2) insufflation, PaCO(2) and PetCO(2) were recorded every 30 min during surgery. RESULTS: No complication was observed during anaesthesia. The mean arterial pressure increased significantly after CO(2) insufflation and remained steady up to the end of pneumoperitoneum. The heart rate remained stable over time. The relation between PaCO(2) and PetCO(2) was not constant among patients and increased over time within the same patients. The R(2) values fluctuated and did not show a constant correlation between PaCO(2) and PetCO(2). CONCLUSION: The correlation between PaCO(2) and PetCO(2) during laparoscopic colon surgery is inconsistent mainly due to inter- and intra-individual variability.

A ten-year analysis of the reasons for death following ambulatory surgery: Nine closed claims declared to the SHAM insurance.

INTRODUCTION: The constant development of ambulatory surgery (AS) raises the problem of monitoring patients after discharge and the risk of death in the case of delays in the management of a serious complication. PATIENTS AND METHODS: The aim of this retrospective study was to describe the deaths observed within the 30-day period following AS declared to the SHAM insurance (Société hospitalière d'assurance mutuelle) over the last 10 years. RESULTS: During the study period 33,962 claims were surgery-related and 11 were for deaths after AS. Two of the death claims were excluded from our study because they occurred after the first month. The surgeries concerned were tonsilectomy (3), cataract (2), inguinal hernia (2), varicose vein stripping (1) and laparoscopy (1). Death occurred on average 5.4 days after the AS, in intensive care (3), during hospitalisation (2), with emergency medical services (1), in an emergency department (1) or at home (2). Anaesthesia was directly implicated in 3 cases: anaphylactic shock (Diamox), pneumoperitoneum (gastric swelling) and hemoperitoneum (mismanagement of anticoagulants). 1 case was due to a pulmonary embolism and 5 to a surgical cause. DISCUSSION-CONCLUSION: There was only one case where the complication was aggravated due to the delay of care provision and this was because of a lack of information on the complications requiring an emergency return (abdominal pain after laparoscopy). In all the other cases, death would also probably have occurred during conventional hospitalisation, either because it was unavoidable or because the patient was too far from the surgery.

[Pre-peritoneal continuous infusion of local anesthetics for pain relief after laparotomy. A preliminary report]. / Infiltration continue prépéritonéale d'anesthésiques locaux pour l'analgésie après laparotomie. Données préliminaires.

INTRODUCTION: Continuous administration of local anesthetic through a catheter placed in the scar of a laparotomy is a postoperative analgesic technique, which seems effective but remains little developed and poorly codified. METHODS: In this prospective evaluation, we present a series of 25 observations of adult patients scheduled for abdominal laparotomy, to which a multiperforate catheter was placed at the end of the intervention by the surgeon in pre-peritoneal position, allowing the continuous perfusion of ropivacaïne over the first 48 postoperative hours. Patients received intravenous paracetamol associated with ketoprophene or nefopam. Opiates were given as rescue analgesics, in case of failure in pain relief, defined on objective criteria measured on visual analogic scale (VAS). RESULTS: The feasibility of the technique was excellent, except in one case of catheter obstruction. Pain was adequately relieved, with a majority of patients having VAS scores lower than 3/10 cm with the VAS, as well as rest as during mobilization. Only 9 patients needed morphine rescue analgesics. There was no sign of clinical overdose nor parietal complication related to the technique. Blood dosages of ropivacaine, carried out among 5 patients having received 600 mg daily, showed serum concentrations below the thresholds of toxicity. CONCLUSIONS: These results reveal a good effectiveness of the method, with moderate pain intensity and a low analgesic consumption. The local and general tolerance was excellent.

New modalities of pain treatment after outpatient orthopaedic surgery.

Postoperative pain relief is one of the cornerstones of success of orthopaedic surgery. Development of new minimally-invasive surgical procedures, as well as improvements in pharmacological and local and regional techniques should result in optimal postoperative pain control for all patients. The analgesic strategy has to be efficient, with minimal side effects, and be easy to manage at home. Multimodal analgesia allows for a reduction of opiate use and thereby its side effects. Local and regional analgesia is a major component of this multimodal strategy, associated with optimal pain relief, even upon mobilization, and it has beneficial effects on postoperative recovery. Ultrasound guidance improves the success rate of distal nerve blocks and makes distal selective blockade possible, helping to preserve the limb's motility. Besides peripheral nerve blocks, local infiltration (incisional and/or intra-articular) is also important to consider. Duration of the nerve blockade is limited after a single injection. This must be taken into consideration to avoid the recurrence of pain when the patient returns home. Continuous perineural blocks using catheters are an option that can be easily managed at home with monitoring by home-care nurses. Extended-release liposomal bupivacaine and adjuvants such as dexamethasone could significantly enhance the duration of the sensory block, thereby reducing the indications for pain pumps. Non-pharmacological approaches, such as cryotherapy, hypnosis and acupuncture should not be ignored.

[Residual neuromuscular blockade]. / Curarisation résiduelle.

Despite the availability of modern neuromuscular blocking agents with short or intermediate duration of action, incidence of residual neuromuscular blockade remains very high. Evidences have been recently provided that residual curarization must be defined as a train-of-four ratio below 0.9 at the thumb adductor during the recovery period after anaesthesia. Residual curarization may be associated with serious adverse events related to respiratory depression, pharyngeal dysfunction, hypoxemia and prolongation of the length of stay in the recovery room. Appropriate choice of drugs, perioperative monitoring of neuromuscular function and large indications of pharmacological reversal may reduce the incidence of residual curarization and improve the patient's safety in the postoperative setting.

An observational evaluation of the rate of awakening after isoflurane or desflurane used in daily clinical practice.

STUDY OBJECTIVE: To evaluate the rate of awakening after desflurane (D) or isoflurane (I) anesthesia when used during daily clinical practice. DESIGN: Observational prospective study. SETTING: University-affiliated metropolitan hospital. PATIENTS: 68 ASA physical status I and II patients (18-75 yrs) scheduled for abdominal surgeries. INTERVENTIONS: Patients scheduled for abdominal surgery of various duration received either D or I. No time was specified for discontinuation of the inhaled drugs at the end of the surgery. T0 for recovery parameters was stated as the end of the surgery. A p-value < 0.05 was considered as significant. Results are expressed as medians and ranges. MEASUREMENTS AND MAIN RESULTS: 68 patients (32 in D group and 36 in I group) were analyzed. Patient demographic data were similar between the two groups. Duration of surgery was 151 minutes (83-428 min) and 174 minutes (40-552 min) for I and D, respectively. Extubation occurred earlier after D (18 min [9-35 min]) as compared to I (32 min [7-77 min]). Time to reach the Aldrete score at 10 was faster after D (30 min [12-45]) as compared to I (46 min [15-110]). Unlike I, the rate of awakening after D was independent of the duration of surgery. The differences between D and I reached statistical significance in surgical procedures lasting more than 100 minutes. CONCLUSION: Used during routine conditions, D allows for faster recovery than I in surgical procedures lasting more than 100 minutes. The rate of awakening after D remained independent of the duration of the surgical procedure.

[Frequency, intensity, development and repercussions of postoperative pain as a function of the type of surgery]. / Fréquence, intensité, évolution et retentissements de la douleur postopératoire en fonction du type de chirurgie.

Type of surgery is the most important factor conditioning intensity and duration of postoperative pain. Thoracic and spinal surgery are the most painful procedures. Abdominal, urologic and orthopedic surgery lead to severe postoperative pain. Duration of severe pain rarely exceeds 72 hours. Mobilization increases pain intensity after abdominal, thoracic and orthopaedic surgery. Pain could occur after daycase minor surgical procedures and is often underestimated. Postoperative complications related to pain are difficult to disclose because of the interposition of the direct effects of analgesic treatments. Respiratory and cardiovascular postoperative complications are unrelated to postoperative pain in healthy subjects. This could be different in high risk patients. The surgical procedure is the major determinant of metabolic and psychologic postoperative deterioration. Adequate pain relief allows postoperative rehabilitation and physiotherapy programmes after abdominal and orthopaedic surgery. This could be expected to reduce hospital stay and improve convalescence.

[Prehabilitation. Preparing patients for surgery to improve functional recovery and reduce postoperative morbidity]. / La préhabilitation. Préparer les patients à la chirurgie pour améliorer la récupération fonctionnelle et réduire la morbidité postopératoire.

OBJECTIVE: Prehabilitation consists in providing a repetitive physical exercise before surgery to improve the postoperative recovery course. This review aims to evaluate the feasibility and the expected benefits of prehabilitation on the postoperative recovery course and the reduction of the postoperative morbidity. DATA SOURCES: Data research has focused on English-language articles in the Medline database, published from 1989 to 2013. Keywords, used separately or in combination, were: prehabilitation, functional capacity, postoperative morbidity, physical activity. STUDY SELECTION: Selected articles were original articles, clinical cases, review articles and meta-analysis. DATA EXTRACTION: Articles were analyzed for feasibility, benefits and limitations of preoperative physical preparation techniques. DATA SYNTHESIS: Poor preoperative functional status is associated with increased postoperative morbidity. Elderly are more prone to postoperative complications. The improvement of preoperative physical status of these patients is possible and may reduce morbidity and allow faster recovery after major surgery. In order to improve efficiency, the training program must provide endurance and muscle reinforcement exercises, whose intensity must be adapted to the patient's baseline physical abilities. An average of three sessions per week over a period of six to eight weeks before surgery seemed a good compromise between feasibility and effectiveness. CONCLUSION: The effectiveness of prehabilitation has been demonstrated in cardiovascular surgery and probably in abdominal surgery. Prehabilitation must be integrated into the overall patient medical management, and must be associated with preoperative refeeding and postoperative rehabilitation protocols. By optimizing all stages of the surgical patient management, from diagnosis to recovery, prognosis of high-risk surgical patients could be improved.

Influence of pain on postoperative ventilatory disturbances. Management and expected benefits.

Abdominal surgery induces postoperative ventilatory dysfunction related to a combination of reflex diaphragmatic inhibition, respiratory muscle injury and pain. The role of pain is difficult to isolate from other components. Thoracic epidural analgesia using local anesthetics is able to partially reverse the diaphragmatic dysfunction. However, this effect seems not directly related to analgesia. Regardless of the mechanisms, epidural analgesia has been shown to improve the postoperative ventilation and to prevent the occurrence of pulmonary complications. Pain relief, either by parenteral administration of opiate, and/or parietal blockade has been shown to improve the diaphragm motion and the overall respiratory status. All analgesic strategies may facilitate the implementation of postoperative physiotherapy which has a significant interest in preventing postoperative pulmonary complications.

[Perioperative management of patients with systemic scleroderma]. / Prise en charge périopératoire du patient sclérodermique.

Systemic sclerosis (SSc) is an auto-immune disease characterized by vasculopathy and the combination of microangiopathy and tissue collagen deposit leading to skin, digestive, pulmonary, myocardial and renal injuries. These repercussions could be challenging for anesthesiologists and associated with difficulties in airway management, and occurrence of congestive right heart failure or acute kidney crisis. The aim of this review is to review the physiopathology and the progression of the SSc, as well as to provide a strategy of perioperative management of these patients.

[Epidemiology of the medico-legal risk associated with the practice of ambulatory surgery in France: a study based on insurance data]. / Épidémiologie du risque médico-légal lié à la pratique de la chirurgie ambulatoire en France: données SHAM.

UNLABELLED: The medico-legal risk specifically associated with the practice of ambulatory surgery is still not well studied. SHAM insurances are the biggest French provider of medical liability insurances. The study of the insurance claims provided by this insurer is therefore a relevant source of data on the complications related to ambulatory surgery. OBJECTIVE: The aim of this study was to compare the claim rate related to ambulatory surgery with non-ambulatory surgery. STUDY DESIGN: We did a retrospective study on insurance claims provided by SHAM insurances between 2007 and 2011 to compare the claim rate related to ambulatory surgery with non-ambulatory surgery. MATERIALS AND METHODS: We searched the files in the SHAM database, and then analyzed them. RESULTS: On the study period, out of a total of 29565 registered claims, 467 (1.6%) originated from ambulatory surgery. On the total of 29,098 registered claims for non-ambulatory surgery, 2151 (7.4%) led to a condemnation whereas the rate was 7% (33 out of 467 claims) for ambulatory surgery. The condemnations linked to ambulatory surgery amounted to 1.5% of the total (33 out of 2184), for a cost of 1.7 M€ (versus 400,3 M€ for non-ambulatory surgery). The average cost of a compensation is therefore 50,500 € for ambulatory surgery and 186,000 € for non-ambulatory surgery. The medical specialties concerned are primarily ophthalmology, abdominal and orthopedics surgery. The main identified causes were medical errors (n=16) and nosocomial infections (n=13). CONCLUSIONS: The claim rate in ambulatory surgery is proportionally less frequent with compensations three times less and were related to the most frequent type of surgery done in ambulatory settings. These data should help strengthen quality approach in ambulatory surgery.
