Multicentre, prospective, double-blind, randomised controlled clinical trial comparing different non-opioid analgesic combinations with morphine for postoperative analgesia: the OCTOPUS study.

BACKGROUND: Head-to-head comparisons of combinations of more than one non-opioid analgesic (NOA) with morphine alone, for postoperative analgesia, are lacking. The objective of this multicentre, randomised, double-blind controlled trial was to compare the morphine-sparing effects of different combinations of three NOAs-paracetamol (P), nefopam (N), and ketoprofen (K)-for postoperative analgesia. METHODS: Patients from 10 hospitals were randomised to one of eight groups: control (C) received saline as placebo, P, N, K, PN, PK, NK, and PNK. Treatments were given intravenously four times a day during the first 48 h after surgery, and morphine patient-controlled analgesia was used as rescue analgesia. The outcome measures were morphine consumption, pain scores, and morphine-related side-effects evaluated 24 and 48 h after surgery. RESULTS: Two hundred and thirty-seven patients undergoing a major surgical procedure were included between July 2013 and November 2016. Despite a failure to reach a calculated sample size, 24 h morphine consumption [median (inter-quartile range)] was significantly reduced in the PNK group [5 (1-11) mg] compared with either the C group [27 (11-42) mg; P<0.05] or the N group [21 (12-29) mg; P<0.05]. Results were similar 48 h after surgery. Patients experienced less pain in the PNK group compared with the C, N, and P groups. No difference was observed in the incidence of morphine-related side-effects. CONCLUSIONS: Combining three NOAs with morphine allows a significant morphine sparing for 48 h after surgery associated with superior analgesia the first 24 h when compared with morphine alone.

[French clinical guidelines for prevention of perianaesthetic dental injuries: long text]. / Bris dentaires périanesthésiques: texte long.

INTRODUCTION: Dental injuries represent the most common claims against the anaesthesiologists. Dental lesions are frequent complications of orotracheal intubation and major causal factors are, firstly, preexisting poor dentition, and, secondly, difficult laryngoscopy and tracheal intubation. The aim of this work was to prioritize propositions for prevention in perianaesthetic dental injury and for care in case of dental trauma. METHOD: A GRADE consensus procedure consisting of three rounds was conducted. A purposively selected heterogeneous panel (n=15) of experts, comprising 10 practitioners in anesthesiology, one practitioner who is jurist and anaesthesiologist, two practitioners in maxillofacial surgery, and two practitioners in dentist surgery. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the board members. The guidelines represent the best current evidence based on literature search and professional opinion. RESULTS: The entire panel completed all three rounds and 31 plus six propositions were written for adult and paediatric clinical practice in anaesthesiology, respectively. The experts highlight the interest of preoperative visit for minimizing dental injuries: the practitioner must identify risk factors for difficult intubation and ventilation, describe precisely patient's preoperative dental condition, including upper incisor most commonly involved teeth in dental trauma. Patients have to be informed by practitioner for risk dental injury and anaesthesiology staff must choose his anesthesia protocol before the induction of intubation narcosis, avoiding insufficient anaesthesia and lack of experience by the anaesthesiologist. The choice of accurate proceeding during laryngoscopy, tracheal intubation and extubation for example, can aid in the prevention of dental injury, reduce the number of claims and the cost of litigation process. DISCUSSION: These guidelines delineate an approach for the prevention of perianaesthetic dental trauma and for the immediate or urgent care in case of perianaesthetic dental injury.

[Wound infiltration with local anesthetics for postoperative analgesia. Results of a national survey about its practice in France]. / Infiltrations d'anesthésiques locaux pour l'analgésie postopératoire chez l'adulte. Résultats d'une enquête nationale de pratique.

BACKGROUND AND OBJECTIVE: Local wound infiltration is a component of multimodal postoperative (p.o.) analgesia. Its implementation in current clinical practice remains unknown. Pain and Regional Anesthesia Committee of the French Anaesthesia and Intensive Care Society (Sfar) aimed to appraise its practice. METHOD: Postal sample survey based on representative sample of national activity were sent to heads of anaesthesiology departments. The questionnaires included 36 items on single-shot and continuous wound infiltrations (CWI) with considerations about modality of administration, drugs and development limitations. Results in mean [CI95 %]. RESULTS: Response rate was 32 % (n=120). Sample was in accordance with national representation of health institutions. Local infiltration was included in 85 % [79-91] of the p.o. analgesia protocols. Regardless of the surgery, single-shot wound infiltration and CWI were used in more than 50 % of the patients by respectively 58 % [49-67] and 18 % [11-25] of the responders. However, a significant part of the surgeons remained reluctant to CWI. Lack of information and fear of septic complications were the most reported barriers. Peritoneal instillation after laparoscopy was rarely performed, in contrast with intra-articular infiltration after knee arthroscopy, performed systematically or very frequently by 60 % [50-70] of the responders. CONCLUSION: The practice of local wound infiltration for p.o. analgesia seems presently well established, especially for single-shot injections. CWI is less commonly performed. Several surgical reluctances remain to be overcome. Better information about effectiveness and safety are likely to still improve their practices.

Regional anaesthesia practice for total knee arthroplasty: French national survey - 2008.

BACKGROUND AND OBJECTIVE: Improved pain management techniques and rehabilitation programs have significantly modified outcome for total knee arthroplasty (TKA). OBJECTIVE: The aim of the survey was to describe the French practice patterns in regional anaesthesia for TKA. METHODS: Twenty-item questionnaires were distributed to units with significant orthopaedic activity across France. The content referred to the type of orthopaedic activity; anaesthetic and analgesic management; preoperative patient information; technical aspects describing regional anaesthesia and postoperative analgesia. RESULTS: Response rate was 54%. Combined general anaesthesia and perineural catheter was the most frequently used anaesthetic technique. Most of respondents used multimodal analgesia (including femoral nerve catheter by 80%). Written hygiene protocols were rarely available. Sterile gowns were seldom worn. Among antiseptic agents, povidone iodine was most often used. Sedative agents were systematically used by 36% of respondents. Ropivacaine was the preferred local anaesthetic agent. Finally, adjuvants were rarely used. In most cases (58%) the femoral block was performed before induction of general anaesthesia. The catheter was commonly threaded to a length between 5 and 8 cm. The correct position of the catheter tip was verified clinically by majority of respondents. Local anaesthetics were administered by continuous infusion, continuous infusion plus boluses and boluses alone in 44, 36 and 8% of cases. Catheter duration was 48 and 72 h in 45 and 33% of the units and was independent of pain scores. CONCLUSION: This national survey showed practices in accordance with recent guidelines as well as persistent challenges in regional anaesthesia for TKA.

[KID syndrome: a cause of pachydermatoglyphia]. / KID syndrome: une cause de pachydermatoglyphie.

INTRODUCTION: The KID syndrome is a rare ectodermal dysplasia associating erythrokeratodermia, deafness and keratitis. Other disorders such as sensitivity to infections or hypohidrosis may be associated. Pachydermatoglyphia is characterized by diffuse hyperkeratosis in which the dermatoglyphe crests are accentuated in thickness and height. CASE REPORT: We report the case of a KID syndrome in a young girl, born of non-consanguine parents and without any familial context. The classical elements of this dysplasia were present: erythrokeratoderma with dryness and roughness of the whole tegument, plicatured pachydermia of the knees, facial erythema, grooves around the mouth, hypotrichosis of the lashes and eyebrows, deafness, and ophthalmologic involvement. Involvement of the palms was characterized by the pachydermatoglyphic aspect. DISCUSSION: In this case report, the palmar keratoderma corresponded to the original description of pachydermatoglyphia and we consider that the KID syndrome should be integrated as a possible etiology of pachydermatoglyphia.

[Preoperative hemodilution by erythrocytapheresis with homologous blood saving in total hip arthroplasty]. / Contribution de l'hémodilution préopératoire par érythrophérèse à l'épargne de sang homologue au cours de l'arthroplastie totale de hanche.

OBJECTIVES: To compare three techniques for decreasing homologous blood requirements in total hip arthroplasty (THA), including preoperative autologous donation (PAD), preoperative acute normovolaemic haemodilution with erythrocytapheresis (erythro) and intraoperative normovolaemic haemodilution (haemo). STUDY DESIGN: Prospective clinical trial. PATIENTS: The study included 45 patients scheduled for THA, under general anaesthesia and operated on by the same surgeon. The patients were allocated into three groups of 15 each. METHODS: Blood loss was assessed, during surgical procedure, by the weight of sponges and, the amount of blood collected in the suction bottles during and after surgery. The haemoglobin concentration was measured at the time of preoperative assessement (d-30), just prior to surgery (d-1), in the recovery room (d+3h), and 1, 3, and 8 days later (d8). The transfusion end-point in the three groups was to obtain a haemoglobin concentration of 100 g.L-1 from d+3h until d8. Every pack of red blood cells transfused was weighed and its haematocrit assessed to determine the accurate volume of red blood cells. RESULTS: In the three groups haemoglobin concentration was similar from d+3h until d8. In the PAD group, no patient required homologous blood transfusion. There was no significant difference between the two other groups in the mean volume of homologous red blood cells required (308 +/- 197 mL in erythro group and 331 +/- 202 mL in the haemo group, respectively). The intraoperative blood loss was significantly higher (P = 0.001) in the erythro group: 914 +/- 305 mL vs 665 +/- 263 in the PAD group and 512 +/- 146 mL in the haemo group, respectively. There was an inverse correlation between haematocrit at d-1 and intraoperative bleeding (r = -0.7) (P = 0.0001). The distribution of the points was fitted as an exponential curve. CONCLUSIONS: In THA, PAD is obviously the best technique to avoid homologous blood transfusion. However, when PAD is not feasible, removal of blood prior to surgery does not decrease requirements of homologous blood, as intraoperative blood loss is higher. Our results strongly question the use of major haemodilution during a surgical procedure exposing a major blood loss.

[Ethnic predisposition of the severity of HELLP syndrome. Retrospective study of 12 cases including 5 during post-partum]. / Prédisposition ethnique de la sévérité du HELLP syndrome. Etude rétrospective de 12 cas dont 5 survenus en post-partum.

HELLP syndrome is characterized by association of haemolysis (H), elevated liver enzymes (EL), and low platelets (LP). From 1989 to 1991, we studied retrospectively 12 cases of HELLP syndrome cases that occurred during the third trimester for 7 cases and during post-partum for 5 cases. 83% of patients (10/12) were black people (African or Creole). The most frequent sign of HELLP syndrome during pre- and post-partum was epigastric or dorsal pain, present in 91% of the cases (11/12) and in all cases of preeclampsia. Aggressive treatment was always performed, leading to 12 births: 7 of the 12 children were hypotrophic for gestational age. There were no maternal or neonatal deaths. Post-partum HELLP syndrome occurred 28.8 hours (mean) after delivery. Whether HELLP syndrome occurred during pre- or post-partum, laboratory findings returned to normal levels after equivalent delays: platelets 57 hours, ASAT 68 hours and ALAT 65 hours.
