Anesthesia Teleconsultation: Quality, Medicoeconomic Interest, and Patient Satisfaction of Preoperative Assessment-A Prospective Observational Study.

Background: Telemedicine can be defined as the use of telecommunication technology for performing medical acts remotely by health professionals. Currently in anesthesia, teleconsultation (TC) is becoming widespread, although the benefit and quality have not been well evaluated. The objective of this study was to assess the quality, the patient satisfaction, as well as the ecological and medicoeconomic impacts of the preanesthesia TC. Methods: This prospective observational multicentric study was approved by the Société Française d'Anesthésie-Réanimation ethics committee. The study took place from October 2020 to March 2021, in eight French health care institutions. Every adult patient requiring TC before elective surgery could be included. Unavailability of videoconferencing for the patient was the main exclusion criteria. Five hundred three (n) patients, scheduled for surgery, were included. Their files were analyzed for quality, 375 were successfully interviewed for the second part of the study evaluating satisfaction and medicoeconomic impact. The study's evaluation criteria were the quality of the TeleMed-Cs, the satisfaction and comprehension for the patient, and the medicoeconomic impact of a remote evaluation compared with the face-to-face consultation with the surgeon. Results: Of the 503 files, 478 (95%) were reviewed and met all the high authority of health quality criteria. The electronic format of records was associated with higher completion rate. The median satisfaction was 10.0 (IQR 8.25-10.0). The cost of a TC in anesthesia was significantly lower than that of a face-to-face surgical consultation with a median cost of 1.49€ (IQR 0.8-1.99) versus 34.81€ (IQR 14.01-91.7) p < 0.001. Conclusions: TC in anesthesia seems to be a good alternative in terms of quality, patient satisfaction, and medicoeconomic gain for our patients. By facilitating access to preoperative evaluation, it could be adopted worldwide and thus reduce surgery-related morbidity and mortality in our patients.

Guidelines on perioperative optimization protocol for the adult patient 2023.

OBJECTIVE: The French Society of Anesthesiology and Intensive Care Medicine [Société Française d'Anesthésie et de Réanimation (SFAR)] aimed at providing guidelines for the implementation of perioperative optimization programs. DESIGN: A consensus committee of 29 experts from the SFAR was convened. A formal conflict-of-interest policy was developed at the outset of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence. METHODS: Four fields were defined: 1) Generalities on perioperative optimization programs; 2) Preoperative measures; 3) Intraoperative measures and; 4) Postoperative measures. For each field, the objective of the recommendations was to answer a number of questions formulated according to the PICO model (population, intervention, comparison, and outcomes). Based on these questions, an extensive bibliographic search was carried out using predefined keywords according to PRISMA guidelines and analyzed using the GRADE® methodology. The recommendations were formulated according to the GRADE® methodology and then voted on by all the experts according to the GRADE grid method. As the GRADE® methodology could have been fully applied for the vast majority of questions, the recommendations were formulated using a "formalized expert recommendations" format. RESULTS: The experts' work on synthesis and application of the GRADE® method resulted in 30 recommendations. Among the formalized recommendations, 19 were found to have a high level of evidence (GRADE 1±) and ten a low level of evidence (GRADE 2±). For one recommendation, the GRADE methodology could not be fully applied, resulting in an expert opinion. Two questions did not find any response in the literature. After two rounds of rating and several amendments, strong agreement was reached for all the recommendations. CONCLUSIONS: Strong agreement among the experts was obtained to provide 30 recommendations for the elaboration and/or implementation of perioperative optimization programs in the highest number of surgical fields.

Wide Awake Local Anesthesia No Tourniquet (WALANT) technique improves the efficiency of distal nerve blocks for carpal tunnel release.

BACKGROUND: Axillary block is the standard for carpal tunnel release (CTR), providing effective anesthesia, and tolerance of tourniquet. Conversely, distal blocks are less used due to poor tolerance of tourniquet. Wide Awake Local Anesthesia No Tourniquet (WALANT), proposed for hand and wrist surgeries, avoids its use. This study assesses the benefits of the addition of WALANT to distal blocks during endoscopic CTR (eCTR). METHODS: This randomized, open-label, controlled trial prospectively enrolled 60 patients scheduled for eCTR. Patients were randomized to receive distal blocks at the wrist combined to either a high arm tourniquet (Distal block group) or a WALANT in the area of surgery (Distal + Walant group). The primary endpoint was the global pain score summing pain scores related to puncture, local anesthetic injection, pneumatic tourniquet, surgical procedure, tourniquet deflation, and residual sensitivity after surgery. RESULTS: Mean global pain score was significantly reduced in the Distal + Walant group (0.5 ± 1.4 vs. 2.2 ± 2.4; p < 0.001). No need for an additional anesthetic procedure was required in the Distal + Walant group. Even if the quality of visualization was high in both groups, it was better in the Distal block group (5 [5-5] vs. 4 [4-5]; p < 0.001). No rescue tourniquet was necessary for the Distal + Walant group. The rate of hematoma 15 days post-surgery was significantly reduced in the Distal + Walant group (20% vs. 57%; p < 0.01). CONCLUSIONS: The addition of WALANT to distal blocks is adapted for eCTR. This combined technique decreases perioperative pain scores, provides good surgery conditions, and reduces the risk of postoperative hematoma. CLINICAL TRIAL NUMBER AND REGISTRY URL: The trial was registered on ClinicalTrials.gov (NCT04494100) on July 31, 2020 https://clinicaltrials.gov/ct2/show/NCT04494100?term=CMC+ambroise+pare&cntry=FR&draw=4&rank=28.

[Assessment of Teleconsultation for planned orthopaedic surgery]. / Faisabilité d'une téléconsultation d'anesthésie en chirurgie orthopédique programmée.

The COVID-19 pandemic has motivated the development of teleconsultation in anaesthesia. We have conducted a single centre prospective study in patients scheduled for planned orthopaedic surgery during 9 weeks between may and july 2020 to assess its practicability. The quality of the consultation and patients' satisfaction, were evaluated during this period. The teleconsultation was successful in 90% of the patients without the need of attendance to the hospital for assessment before anaesthesia. The process was satisfactory for 97% of these patients. The mean duration was 15 minutes. The support of a third party was required in 46% of patients older than 65 years. The main cause of failure was the poor quality of the connection. Only two patients were cancelled for surgery because they did not understand fasting rule. The teleconsultation is now an integral part of preoperative assessment of patients for anaesthesia with good practicability and reliability.

Guidelines: Anaesthesia in the context of COVID-19 pandemic.

OBJECTIVES: The world is currently facing an unprecedented healthcare crisis caused by the COVID-19 pandemic. The objective of these guidelines is to produce a framework to facilitate the partial and gradual resumption of intervention activity in the context of the COVID-19 pandemic. METHODS: The group has endeavoured to produce a minimum number of recommendations to highlight the strengths to be retained in the 7 predefined areas: (1) protection of staff and patients; (2) benefit/risk and patient information; (3) preoperative assessment and decision on intervention; (4) modalities of the preanaesthesia consultation; (5) specificity of anaesthesia and analgesia; (6) dedicated circuits and (7) containment exit type of interventions. RESULTS: The SFAR Guideline panel provides 51 statements on anaesthesia management in the context of COVID-19 pandemic. After one round of discussion and various amendments, a strong agreement was reached for 100% of the recommendations and algorithms. CONCLUSION: We present suggestions for how the risk of transmission by and to anaesthetists can be minimised and how personal protective equipment policies relate to COVID-19 pandemic context.

Tranexamic acid in severe trauma patients managed in a mature trauma care system.

BACKGROUND: Tranexamic acid (TXA) use in severe trauma remains controversial notably because of concerns of the applicability of the CRASH-2 study findings in mature trauma systems. The aim of our study was to evaluate the outcomes of TXA administration in severely injured trauma patients managed in a mature trauma care system. METHODS: We performed a retrospective study of data prospectively collected in the TraumaBase registry (a regional registry collecting the prehospital and hospital data of trauma patients admitted in six Level I trauma centers in Paris Area, France). In hospital mortality was compared between patients having received TXA or not in the early phase of resuscitation among those presenting an unstable hemodynamic state. Propensity score for TXA administration was calculated and results were adjusted for this score. Hemodynamic instability was defined by the need of packed red blood cells (pRBC) transfusion and/or vasopressor administration in the emergency room (ER). RESULTS: Among patients meeting inclusion criteria (n = 1,476), the propensity score could be calculated in 797, and survival analysis could be achieved in 684 of 797. Four hundred seventy (59%) received TXA, and 327 (41%) did not. The overall hospital mortality rate was 25.7%. There was no effect of TXA use in the whole population but mortality was lowered by the use of TXA in patients requiring pRBC transfusion in the ER (hazard ratio, 0.3; 95% confidence interval, 0.3-0.6). CONCLUSION: The use of TXA in the management of severely injured trauma patients, in a mature trauma care system, was not associated with reduction in the hospital mortality. An independent association with a better survival was found in a selected population of patients requiring pRBC transfusion in the ER. LEVEL OF EVIDENCE: Therapeutic study, level III.

Outpatient Appendectomy in an Emergency Outpatient Surgery Unit 24 h a Day: An Intention-to-Treat Analysis of 194 Patients.

OBJECTIVE: To evaluate the feasibility and outcomes of patients operated on for uncomplicated acute appendicitis (UAA) in our 24-h emergency outpatient surgery unit. METHODS: This was a prospective observational study with intention-to-treat (ITT) analysis. From 12/2013 to 03/2015, all consecutive patients admitted for acute appendicitis (AA) were prospectively screened. A computed tomography or abdominal ultrasound confirmed the diagnosis of AA. Eligibility criteria for outpatient appendectomy were: UAA, no comorbidity, no physical or mental condition preventing participation in the study, absence of pregnancy, age older than 15 years, an accompanying adult person available for the hospital discharge and place of residence within 1 h of our hospital. In the case of intraoperative complication (abscess, local or general peritonitis) or complication of general anesthesia, patients were excluded from the outpatient pathway. The primary endpoint was the feasibility of outpatient appendectomy among all consecutive patients admitted for UAA. RESULTS: Of the 194 screened patients, 150 (77%) presented an UAA and 102 (68%) were eligible for an outpatient procedure. Thirteen eligible patients (13%) were excluded from the outpatient circuit (7 intraoperative and 6 postoperative contraindications). Outpatient appendectomy was performed in 89 patients, representing 59% (89/150) of the ITT population and 87% (89/102) of the eligible patients. The median length of hospital stay was 13 h. Postoperative complications were observed in six patients (6%). CONCLUSIONS: This study reports a safe and feasible management of UAA. Our organization allows a short hospitalization for postoperative recovery without using conventional surgery beds and enables discharge throughout the night.

Continuous interscalene brachial plexus nerve block prolongs unilateral diaphragmatic dysfunction.

BACKGROUND AND OBJECTIVES: Single interscalene blocks (ISB) impair pulmonary function (<24h). We hypothesized that continuous ISBs would prolong pulmonary dysfunction until h48 compared with a single ISB. We compared the time course of spirometric and diaphragmatic dysfunction following single or continuous ISBs. METHODS: We prospectively included consecutive adult patients scheduled to undergo shoulder surgery under standard general anaesthesia with single (n=30) or continuous (n=31) ISB. Before ISB (baseline), spirometric tests were recorded and the diaphragm course was evaluated with a B-mode ultrasound technique every 12h until h48. ISBs were performed with 15mL 0.5% ropivacaine using an ultrasound technique approach. The continuous group received the same bolus followed by 0.2% ropivacaine 5mL·h-1 (48h). The primary end point was the reduction (> 25% from baseline) of forced vital capacity (FVC) over the study period (48h). RESULTS: Patient characteristics were similar in both groups. Thirty minutes after blocks in the PACU, all patients demonstrated a similar and significant unilateral diaphragm paralysis (< 25% from baseline). For the primary end point (FVC), no significant difference was observed between groups over the study period. A difference between single and continuous groups was observed at h24 for: FVC (-25%, P=0.038), FEV1s (-24%, P=0.036), diaphragmatic course (-26%, P=0.02), while no differences for other time points (h0-h48) were noted. Clinical respiratory evaluations (respiratory rate, SpO2, supplementary nasal O2), postoperative pain scores and additional opioid consumption were similar between groups. CONCLUSION: Over infusion, continuous ISB did not significantly prolong unilateral phrenic paresis and demonstrated a limited pulmonary impact.

[Sciatic perineural catheters: an alternative analgesia for diabetic patients]. / Cathéters sciatiques: une alternative analgésique chez les patients diabétiques.

INTRODUCTION: Patients with diabetes mellitus have chronic neuropathic pain. The aim of our study was to 1) evaluate the feasibility of providing analgesia with a long-term sciatic perineural catheter in a medical unit for diabetic patients and 2) evaluate its effectiveness. METHODS: A prospective, monocentric, non-randomized study was conducted over two years. All diabetic patients with an ineffective optimal systemic treatment were included. Written consent was obtained. Popliteal-sciatic nerve catheters were inserted under ultrasound guidance; ropivacaine was started. The primary endpoint was pain at Day 2. Pain intensity was measured using a numeric rating scale (NRS). Secondary endpoints were patient's pain relief, the impact on quality of life, and morphine consumption, evaluated at Day 0, Day 2, at the time of catheter removal, and one month after catheter removal. RESULTS: Feasibility was evaluated over one year. Fifty-five perineural catheters were placed in 32 patients. The median duration of catheter placement across patients was 13 [4-23] days. No toxic or infectious complications were seen. Effectiveness was evaluated during the second year of the study. Seventeen catheters were placed in 12 patients; 83% of patients had a NRS score ≤3 at Day 2. More than 70% of patients experienced pain relief while the catheter was in place and at one month after its removal. The impact on quality of life was negligible. Morphine consumption was less on Day 2, at the time of catheter removal and one month after removal. CONCLUSION: The use of sciatic perineural catheters as an alternative analgesia technique in a non-surgical environment for diabetic patients with chronic pain was possible and effective.

Impact of aspirin and clopidogrel interruption on platelet function in patients undergoing major vascular surgery.

AIMS: To investigate functional platelet recovery after preoperative withdrawal of aspirin and clopidogrel and platelet function 5 days after treatment resumption. METHODS/RESULTS: We conducted an observational study, which prospectively included consecutive patients taking aspirin, taking clopidogrel, and untreated controls (15 patients in each group). The antiplatelet drugs were withdrawn five days before surgery (baseline) and were reintroduced two days after surgery. Platelet function was evaluated by optical aggregation in the presence of collagen, arachidonic acid (aspirin) and ADP (clopidogrel) and by VASP assay (clopidogrel). Platelet-leukocyte complex (PLC) level was quantified at each time-point. At baseline, platelet function was efficiently inhibited by aspirin and had recovered fully in most patients 5 days after drug withdrawal. PLC levels five days after aspirin reintroduction were similar to baseline (+4±10%; p = 0.16), in line with an effective platelet inhibition. Chronic clopidogrel treatment was associated with variable platelet inhibition and its withdrawal led to variable functional recovery. PLC levels were significantly increased five days after clopidogrel reintroduction (+10±15%; p = 0.02), compared to baseline. CONCLUSIONS: Aspirin withdrawal 5 days before high-bleeding-risk procedures was associated with functional platelet recovery, and its reintroduction two days after surgery restored antiplaletet efficacy five days later. This was not the case of clopidogrel, and further work is therefore needed to define its optimal perioperative management.

[Last updates about amniotic fluid embolism and a case report]. / L'embolie amniotique : données récentes et illustration.

Amniotic fluid embolism (AFE) is a rare complication of pregnancy, which, in France, is the second leading cause of maternal mortality. It results from the passage of amniotic fluid into the maternal circulation, but mechanisms leading to clinical signs are not yet clearly identified. After a literature review, we report on the case of a 34 years old patient occurred during labor. Laboratory tests were performed during acute phase to diagnose coagulopathy and to monitor vital parameters. Further laboratory tests were conducted to support the diagnosis: cytology, study of insulin-like growth factor-binding protein 1, tryptase and alpha-foetoprotein. Performances and place of these laboratory tests must be precised as no specific test can attest the diagnosis.

Concordance between transcutaneous and arterial measurements of carbon dioxide in an ED.

BACKGROUND: Transcutaneous carbon dioxide pressure (PtcCO(2)) has been suggested as a noninvasive surrogate of arterial carbon dioxide pressure (PaCO(2)). Our study evaluates the reliability of this method in spontaneously breathing patients in an emergency department. PATIENTS AND METHODS: A prospective, observational study was performed in nonintubated dyspneic patients who required measurement of arterial blood gases. Simultaneously and blindly to the physicians in charge, PtcCO(2) was measured using a TOSCA 500 monitor (Radiometer, Villeurbanne, France). Agreement between PaCO(2) and PtcCO(2) was assessed using the Bland-Altman method. RESULTS: Forty-eight patients (mean age, 65 years) were included, and 50 measurements were done. Eleven (23%) had acute heart failure; 10 (21%), pneumonia; 7 (15%), acute asthma; and 7 (15%), exacerbation of chronic obstructive pulmonary disease. Median PaCO(2) was 42 mm Hg (range, 17-109). Mean difference between PaCO(2) and PtcCO(2) was 1 mm Hg with 95% limits of agreement of -3.4 to +5.6 mm Hg. All measurement differences were within 5 mm Hg, and 32 (64%) were within 2 mm Hg. CONCLUSION: Transcutaneous carbon dioxide pressure accurately predicts PaCO(2) in spontaneously breathing patients.
