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.

Standardizing nomenclature in regional anesthesia: an ASRA-ESRA Delphi consensus study of upper and lower limb nerve blocks.

BACKGROUND: Inconsistent nomenclature and anatomical descriptions of regional anesthetic techniques hinder scientific communication and engender confusion; this in turn has implications for research, education and clinical implementation of regional anesthesia. Having produced standardized nomenclature for abdominal wall, paraspinal and chest wall regional anesthetic techniques, we aimed to similarly do so for upper and lower limb peripheral nerve blocks. METHODS: We performed a three-round Delphi international consensus study to generate standardized names and anatomical descriptions of upper and lower limb regional anesthetic techniques. A long list of names and anatomical description of blocks of upper and lower extremities was produced by the members of the steering committee. Subsequently, two rounds of anonymized voting and commenting were followed by a third virtual round table to secure consensus for items that remained outstanding after the first and second rounds. As with previous methodology, strong consensus was defined as ≥75% agreement and weak consensus as 50%-74% agreement. RESULTS: A total of 94, 91 and 65 collaborators participated in the first, second and third rounds, respectively. We achieved strong consensus for 38 names and 33 anatomical descriptions, and weak consensus for five anatomical descriptions. We agreed on a template for naming peripheral nerve blocks based on the name of the nerve and the anatomical location of the blockade and identified several areas for future research. CONCLUSIONS: We achieved consensus on nomenclature and anatomical descriptions of regional anesthetic techniques for upper and lower limb nerve blocks, and recommend using this framework in clinical and academic practice. This should improve research, teaching and learning of regional anesthesia to eventually improve patient care.

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.

Standardizing nomenclature in regional anesthesia: an ASRA-ESRA Delphi consensus study of abdominal wall, paraspinal, and chest wall blocks.

BACKGROUND: There is heterogeneity in the names and anatomical descriptions of regional anesthetic techniques. This may have adverse consequences on education, research, and implementation into clinical practice. We aimed to produce standardized nomenclature for abdominal wall, paraspinal, and chest wall regional anesthetic techniques. METHODS: We conducted an international consensus study involving experts using a three-round Delphi method to produce a list of names and corresponding descriptions of anatomical targets. After long-list formulation by a Steering Committee, the first and second rounds involved anonymous electronic voting and commenting, with the third round involving a virtual round table discussion aiming to achieve consensus on items that had yet to achieve it. Novel names were presented where required for anatomical clarity and harmonization. Strong consensus was defined as ≥75% agreement and weak consensus as 50% to 74% agreement. RESULTS: Sixty expert Collaborators participated in this study. After three rounds and clarification, harmonization, and introduction of novel nomenclature, strong consensus was achieved for the names of 16 block names and weak consensus for four names. For anatomical descriptions, strong consensus was achieved for 19 blocks and weak consensus was achieved for one approach. Several areas requiring further research were identified. CONCLUSIONS: Harmonization and standardization of nomenclature may improve education, research, and ultimately patient care. We present the first international consensus on nomenclature and anatomical descriptions of blocks of the abdominal wall, chest wall, and paraspinal blocks. We recommend using the consensus results in academic and clinical practice.

Efficacy of parasternal block to decrease intraoperative opioid use in coronary artery bypass surgery via sternotomy: a randomized controlled trial.

OBJECTIVE: This study aims to assess the effect of a preoperative parasternal plane block (PSB) on opioid consumption required to maintain hemodynamic stability during sternotomy for coronary artery bypass graft surgery. METHODS: This double-blind, randomized, placebo-controlled trial prospectively enrolled 35 patients scheduled for coronary artery bypass graft surgery under general anesthesia with propofol and remifentanil. Patients were randomized to receive preoperative PSB using either ropivacaine (PSB group) or saline solution (placebo group) (1:1 ratio). The primary endpoint was the maximal effect-site concentration of remifentanil required to maintain heart rate and blood pressure within the recommended ranges during sternotomy. RESULTS: Median maximum concentration of remifentanil necessary to maintain adequate hemodynamic status during sternotomy was significantly reduced in PSB group (4.2 (2.5-6.0) ng/mL) compared with placebo group (7.0 (5.2-8.0) ng/mL) (p=0.02). Mean maximum concentration of propofol used to control depth of anesthesia was also reduced (3.9±1.1 µg/mL vs 5.0±1.5 µg/mL, PSB vs placebo, respectively; p=0.02). This reduction in propofol consumption during sternotomy enabled a more adequate level of sedation to be maintained in patients (minimum patient state index was 11.7±8.7 in placebo group and 18.3±6.8 in PSB group; p=0.02). PSB reduced postoperative inflammatory response by limiting concentrations of proinflammatory cytokines IL-8, IL-18, IL-23, IL-33 and MCP-1 measured in the first 7-day after surgery (p<0.05). CONCLUSIONS: Preoperative PSB reduced the maximum concentrations of remifentanil and propofol required to maintain hemodynamic stability and depth of anesthesia during sternotomy.

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.

Impact of a Hypnotically-Based Intervention on Pain and Fear in Women Undergoing Labor.

The purpose of this study was to evaluate the effects of a hypnotically-based intervention for pain and fear in women undergoing labor who are about to receive an epidural catheter. A group of 155 women received interventions that included either (a) patient rocking, gentle touching, and hypnotic communication or (b) patient rocking, gentle touching, and standard communication. The authors found that the hypnotic communication intervention was more effective than the standard communication intervention for reducing both pain intensity and fear. The results support the use of hypnotic communication just before and during epidural placement for women who are in labor and also indicate that additional research to evaluate the benefits and mechanism of this treatment is warranted.

Shoulder position influences the location of the musculocutaneous nerve in the axillary fossa.

In the axillary fossa, the musculocutaneous nerve (MC) is generally distant from the axillary artery and from the other brachial plexus nerves. In that way, MC requires a specific block. We observed that the location of MC is influenced by the position of the patient's arm and shoulder. Abduction of the shoulder significantly reduced the distance between the MC and the axillary artery. This change in the location of the MC is probably due to the moving of the nerve because of muscle rearrangements and the ability to achieve better proximity of the probe in the axillary fossae.

Clinical, biological, and microbiological pattern associated with ventriculostomy-related infection: a retrospective longitudinal study.

BACKGROUND: Our aim was to describe the pattern of ventriculostomy-related infection (VRI) development using a dynamic approach. STUDY DESIGN: Retrospective longitudinal study. METHODS: We analyzed the files of 449 neurosurgical patients who underwent placement of external ventricular drain (EVD). During the study period, CSF sampling was performed on a daily base setting. VRI was defined as a positive CSF culture resulting in antibiotic treatment. For VRI patients, we arbitrary defined day 0 (D0) as the day antibiotic treatment was started. In these patients, we compared dynamic changes in clinical and biological parameters at four pre-determined time points: (D-4, D-3, D-2, D-1) with those of D0. For all CSF-positive cultures, we compared CSF biochemical markers' evolution pattern between VRI patients and the others, considered as a control cohort. RESULTS: Thirty-two suffered from VRI. Peripheral white blood cell count did not differ between D-4-D0. Median body temperature, CSF cell count, median Glasgow Coma Scale, CSF protein, and glucose concentrations were significantly different between D-4, D-3, D-2, and D0. At D0, 100 % of CSF samples yielded organisms in culture. The physician caring for the patient decided to treat VRI based upon positive CSF culture in only 28 % (9/32) of cases. In the control cohort, CSF markers' profile trends to normalize, while it worsens in the VRI patients. CONCLUSIONS: We showed that clinical symptoms and biological abnormalities of VRI evolved over time. Our data suggest that VRI decision to treat relies upon a bundle of evidence, including dynamic changes in CSF laboratory exams combined with microbiological analysis.

Evaluation of a new disinfection method for ultrasound probes used for regional anesthesia: ultraviolet C light.

OBJECTIVES: Ultrasound-guided regional anesthesia is commonly used for block placement. At present, the risk of cross contamination from probes is not well documented. To avoid transmission of infectious agents, several methods have been used for probe disinfection and protection. The aim of this study was to evaluate the antibacterial efficacy of a new high-level disinfection method based on ultraviolet C (UV-C) light under routine conditions after block placement with an unprotected probe. METHODS: The study was after approval by the local Ethics Committee. In the first part of the study, 15 ultrasound probes were exposed to a large inoculum of 3 bacteria. Ultraviolet C disinfection consisted of cleaning the probe with dry and disinfectant-impregnated paper followed by a 90-second UV-C disinfection cycle in a decontamination chamber. A protocol was established to retrieve the probe with sterile gloves after opening the door of the chamber. In the second part, 50 blocks were placed with ultrasound-guided regional anesthesia. The skin was first prepared with an antiseptic solution, and sterile gel was applied; no covers were used to protect the probes. The blocks were then disinfected with UV-C light. Bacteriologic samples were collected before and after the UV-C method and inoculated on chocolate agar plates. RESULTS: During the first part of the study, all probes were infected after inoculation (>150 colony-forming units) but were considered sterile (<10 colony-forming units) after disinfection. During the second part of the study, all probes were considered sterile before and after disinfection. CONCLUSIONS: Ultraviolet C disinfection seems relevant for ultrasound-guided regional anesthesia just before block placement. It offers simple, fast, and effective high-level disinfection. Moreover, this method should obviate the use of sterile probe covers, which can improve echogenicity.

An algorithm for difficult airway management, modified for modern optical devices (Airtraq laryngoscope; LMA CTrach™): a 2-year prospective validation in patients for elective abdominal, gynecologic, and thyroid surgery.

BACKGROUND: Because algorithms for difficult airway management, including the use of new optical tracheal intubation devices, require prospective evaluation in routine practice, we prospectively assessed an algorithm for difficult airway management that included two new airway devices. METHODS: After 6 months of instruction, training, and clinical testing, 15 senior anesthesiologists were asked to use an established algorithm for difficult airway management in anesthetized and paralyzed patients. Abdominal, gynecologic, and thyroid surgery patients were enrolled. Emergency, obstetric, and patients considered at risk of aspiration were excluded. If tracheal intubation using a Macintosh laryngoscope was impossible, the Airtraq laryngoscope (VYGON, Ecouen, France) was recommended as a first step and the LMA CTrach™ (SEBAC, Pantin, France) as a second. A gum elastic bougie was advocated to facilitate tracheal access with the Macintosh and Airtraq laryngoscopes. If ventilation with a facemask was impossible, the LMA CTrach™ was to be used, followed, if necessary, by transtracheal oxygenation. Patient characteristics, adherence to the algorithm, efficacy, and early complications were recorded. RESULTS: Overall, 12,225 patients were included during 2 yr. Intubation was achieved using the Macintosh laryngoscope in 98% cases. In the remainder of the cases (236), a gum elastic bougie was used with the Macintosh laryngoscope in 207 (84%). The Airtraq laryngoscope success rate was 97% (27 of 28). The LMA CTrach™ allowed rescue ventilation (n = 2) and visually directed tracheal intubation (n = 3). In one patient, ventilation by facemask was impossible, and the LMA CTrach™ was used successfully. CONCLUSIONS: Tracheal intubation can be achieved successfully in a large cohort of patients with a new management algorithm incorporating the use of gum elastic bougie, Airtraq, and LMA CTrach™ devices.
