Impact of Chloroprocaine on the Eligibility for Hospital Discharge in Patients Requiring Ambulatory Surgery Under Spinal Anesthesia: An Observational Multicenter Prospective Study.

INTRODUCTION: This observational study was designed to assess the use of spinal anesthesia with chloroprocaine in the context of ambulatory surgery. METHODS: A prospective, multicenter, observational study was carried out among 33 private or public centers between May 2014 and January 2015 and adult patients, scheduled for a short ambulatory surgery under spinal anesthesia with chloroprocaine. The primary outcomes were anesthetic effectiveness, defined as performance of the whole surgical procedure without any additional anesthetic agent, and the time to achieve eligibility for hospital discharge. Secondary outcomes were the effect of chloroprocaine on motor and sensory blocks, patients' satisfaction, and the use of analgesics in the first 24 h after surgery. RESULTS: Among the 615 enrolled patients, 56% were male, the mean age was 47.2 ± 15.2 years, and most patients had an ASA (American Society of Anesthesiologists) status of 1 (63.7%). Main surgical procedures performed were orthopedic (62.6%) and gynecologic (16.1%), and the mean duration of surgery was 26.7 ± 16.7 min. The overall anesthetic success rate was 93.8% (95% CI [91.5%; 95.6%]) for the 580 patients with available data for primary criteria. The failure rate was lower than 7% for all surgical procedures, except for gynecologic surgery (14.8%; 95% CI [8.1%; 23.9%]). The average times of eligibility for hospital discharge and effective discharge were 252.7 ± 82.7 min and 313.8 ± 109.9 min, respectively. The time of eligibility for hospital discharge is defined as the recovery of the patient's normal clinical parameters and the time of effective discharge is defined as the time for the patient to leave the hospital after surgery. Eligibility for patient's discharge was achieved more rapidly in private than public hospitals (236.3 ± 77.2 min vs. 280.9 ± 80.7 min, respectively, p < 0.001). CONCLUSIONS: This study showed positive results on the effectiveness of chloroprocaine as a short-duration anesthetic and could be used to reduce the time to achieve eligibility for hospital discharge.

Factors Determining the Choice of Spinal Versus General Anesthesia in Patients Undergoing Ambulatory Surgery: Results of a Multicenter Observational Study.

INTRODUCTION: Available short-acting intrathecal anesthetic agents (chloroprocaine and prilocaine) offer an alternative to general anesthesia for short-duration surgical procedures, especially ambulatory surgeries. Factors determining the choice of anesthesia for short-duration procedures have not been previously identified. METHODS: This observational, prospective, multicenter, cohort study was conducted between July 2015 and July 2016, in 33 private or public hospitals performing ambulatory surgery. The primary objective was to determine the factors influencing the choice of anesthetic technique (spinal or general anesthesia). Secondary outcomes included efficacy of the anesthesia, time to hospital discharge, and patient satisfaction. RESULTS: Among 592 patients enrolled, 309 received spinal anesthesia and 283 underwent general anesthesia. In both study arms, the most frequently performed surgical procedures were orthopedic and urologic (43.3% and 30.7%, respectively); 66.1% of patients were free to choose their type of anesthesia, 21.8% chose one of the techniques because they were afraid of the other, 16.8% based their choice on the expected ease of recovery, 19.2% considered their degree of anxiety/stress, and 16.9% chose the technique on the basis of its efficacy. The median times to micturition and to unassisted ambulation were significantly shorter in the general anesthesia arm compared with the spinal anesthesia arm (225.5 [98; 560] min vs. 259.0 [109; 789] min; p = 0.0011 and 215.0 [30; 545] min vs. 240.0 [40; 1420]; p = 0.0115, respectively). The median time to hospital discharge was equivalent in both study arms. In the spinal anesthesia arm, patients who received chloroprocaine and prilocaine recovered faster than patients who received bupivacaine. The time to ambulation and the time to hospital discharge were shorter (p < 0.001). The overall success rate of spinal anesthesia was 91.6%, and no significant difference was observed between chloroprocaine, prilocaine, and bupivacaine. The patients' global satisfaction with anesthesia and surgery was over 90% in both study arms. CONCLUSIONS: Patient's choice, patient fear of the alternative technique, patient stress/anxiety, the expected ease of recovery, and the efficacy of the technique were identified as the main factors influencing patient choice of short-acting local anesthesia or general anesthesia. Spinal anesthesia with short-acting local anesthetics was preferred to general anesthesia in ambulatory surgeries and was associated with a high degree of patient satisfaction.

Perioperative pain and post-operative nausea and vomiting (PONV) management after day-case surgery: The SFAR-OPERA national study.

OBJECTIVES: Since pain and post-operative nausea and vomiting (PONV) are the main reasons for failed discharge after day-case surgery, assessing pain and PONV is important. The aim was to describe the perioperative pain and PONV management within selected day-case surgical procedures in France. METHODS: The OPERA trial was carried out on given days between December 2013 and December 2014. Each participating centre was required to fill out 3 separate questionnaires aiming at describing (1) protocols about pain and PONV, (2) patients' characteristics and procedures, (3) analgesic and PONV practice patterns for selected procedures. RESULTS: Over the two days of investigation in each of the 221 randomly selected healthcare institutions, 7382 patients were included, of whom 2144 patients above 12 years underwent one of 10 selected procedures. Among responding institutions, 40% [33;47] had a dedicated pain management written protocol. Combination of tramadol and paracetamol was the most commonly prescribed (78% [71;83] of centres). Oral morphine was prescribed in 59/199 (30% [23; 37]) centres, for home treatment in 25/59 (42% [30; 56]) centres. However, there was no standardised take-home analgesic and PONV strategies for selected surgical procedures at risk of moderate to severe pain. PONV management guidance after discharge was included in only 12 % of centres. CONCLUSION: This survey demonstrates that practice patterns for pain treatment and PONV prophylaxis after ambulatory surgery vary among French centres and are not always in line with national guidelines. Strategies to improve practices and make them more homogeneous are necessary.

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.

The structure, organisation and perioperative management of ambulatory surgery and anaesthesia in France: Methodology of the SFAR-OPERA study.

The organization of health care establishments and perioperative care are essential for ensuring the quality of care and safety of patients undergoing outpatient surgery. In order to correctly inventory these organizations and practices, in 2013-2014, the French society of anaesthesia and intensive care organized an extensive practical survey in French ambulatory surgery units entitled the "OPERA" study (Organisation periopératoire de l'anesthésie en chirurgie ambulatoire). From among all of the ambulatory surgery centres listed by the Agences régionales de santé (Regional health agencies, France), 206 public and private centres were randomly selected. A structural (typology, organization) survey and a medical-practice survey (focusing on the management of postoperative pain, nausea and vomiting as well as the prevention of venous thromboembolism) were collected and managed by a prospective audit of practices occurring on two randomly selected days. The latter was further accompanied by an additional audit specifically focussing on ten representative procedures: (1) stomatology surgery (third molar removal); (2) knee arthroscopy; (3) surgery of the abdominal wall (including inguinal hernia); (4) perianal surgery; (5) varicose vein surgery; (6) digestive laparoscopy-cholecystectomy; (7) breast surgery (tumourectomy); (8) uterine surgery; (9) hallux valgus and (10) hand surgery (excluding carpal tunnel). Over the 2 days of observation, 7382 patients were included comprising 2174 patients who underwent one of the procedures from the above list. The analysis of these data will provide an overview of the organization of health establishments, the modalities thus supported and compliance with standards.
