RESUMEN
Background: Data and interventions are lacking for family-centred perioperative care in adults. Perioperative information given to relatives by nurses or surgeons is associated with improved satisfaction and fewer symptoms of anxiety for relatives and the patient themselves. However, the frequency of the provision of information by anaesthesiologists to patients' relatives during surgery has never been reported. Methods: A cross-sectional survey was sent to French anaesthesiologists in October 2020 to inquire how often they provided information to patients' family members during surgery and what factors led to them providing information frequently (i.e. in more than half of cases). Results: Among 607 anaesthesiologists, 53% (319/607) were male, with median age 47 (36-60) yr and nearly half (43%, 260/607) reported more than 20 years of clinical experience; most responders (96%, 580/607) mainly treated adults. Forty-nine (8%) anaesthesiologists declared that they frequently provide information to relatives during surgery. After multivariate analysis, age >50 yr, female gender, and paediatric practice were associated with providing information more frequently. Reasons for not providing information included a lack of time and dedicated space to talk to relatives. Urgent surgery or surgery lasting >2 h were identified as factors associated with provision of information to relatives. Conclusions: Giving information to relatives during surgery is not a common practice among anaesthesiologists. It depends on individual anaesthesiologists' personal characteristics and practice. Information during surgery could be provided systematically in situations identified as being the most important by anaesthesiologists in our survey. By creating new pathways of information, we could reduce stress and anxiety of patients and relatives.
RESUMEN
BACKGROUND: Using a Macintosh-style videolaryngoscope as a first-intention device for tracheal intubation of unselected patients in the operating room has not often been studied. We hypothesised that using a Macintosh-style videolaryngoscope as a first-intention device is associated with an increased proportion of easy tracheal intubation. METHODS: In a quality improvement project for airway management aimed at implementing a Macintosh-style videolaryngoscope as a first-intention device, we included all consecutive tracheal intubations in adults from March, 2017 to September, 2020 in two French teaching hospitals. We divided the cohort into three temporal cohorts: the pre-intervention, implementation, and post-intervention periods. The primary outcome was the proportion of easy airway management. The secondary outcomes were the rescue technique, Cormack-Lehane III or IV view, and operator-reported difficulty of intubation. Data from one hospital compliant with the quality improvement project were compared with data from a non-compliant hospital. RESULTS: A total of 26 692 tracheal intubations were performed. Among 11 938 intubations included in the compliant hospital, 5487 were included in the pre-intervention, 1845 in the implementation, and 4606 in the post-intervention periods. In comparison to the pre-intervention period, the proportions of easy tracheal intubation increased from 94.3% (5177 of 5487) to 98.7% (4547 of 4606)) in the post-intervention period (+4.4% [95% confidence interval 3.7-5.1%], P<0.001). In comparison to the pre-intervention period, all secondary outcome proportions were significantly lower in the post-intervention period. No significant changes were noted in the non-compliant hospital between the pre- and post-intervention periods. CONCLUSIONS: Using a Macintosh-style videolaryngoscope as a first-intention device for tracheal intubation in the operating room was associated with a significant increase in the proportion of easy tracheal intubation, compared with use of the standard Macintosh laryngoscope.

BACKGROUND: "Macintosh"-videolaryngoscopes (VLs) are VLs that allow both direct and indirect laryngoscopy for intubation. We describe the decision-making and implementation-processes that our hospital used regarding the choice of device. We compared the performances of 4 Macintosh-VLs both in direct and indirect laryngoscopy. METHODS: A quality-improvement-project for airway management aiming at implementing Macintosh-VL for all intubation procedures performed in the operating room, involving 4 Macintosh-VLs (McGrath-Mac, C-MAC-S, C-MAC-S-Pocket-Monitor [PM], and APA). Three consecutive steps were described: (1) direct laryngoscopy with Macintosh-VL, (2) indirect laryngoscopy with Macintosh-VL (intubation attempt with Macintosh-style blade in case of Cormack I or II), (3) intubation attempt with hyperangulated blade in case of Cormack III/IV or failure of Macintosh-style blade. The main end point was the need to move to step III and use a hyperangulated blade. A mixed-effects multivariable logistic regression analysis was performed to compare devices on the main end point while considering site as a random effect. Comparison of means was performed using analysis of variance and Tukey's test for multiple comparisons (number of laryngoscopy attempts, numeric rate scale [NRS] difficulty of intubation and NRS user-friendliness). Comparison of percentages was performed using a χ2 test for the need to move to step III and a Kruskal-Wallis test for the quality of image (bad, passable, good, very good, excellent). A P value ≤.008 was considered statistically significant. RESULTS: From May to September 2017, 589 patients were included. Using the McGrath-Mac (22/180 [12%]) was associated with less use of hyperangulated blade than using the C-MAC-S (39/132 [30%], odds ratio [OR] [99.2% confidence interval {CI}] 0.34 [0.16-0.77], P = .0005), the APA (35/138 [25%], OR [99.2% CI] 0.42 [0.19-0.93]; P = .004), but not the C-MAC-S-PM (29/139 [21%], OR [99.2% CI] 0.53 [0.23-1.2]; P = .04).Overall, the number of intubation attempts was significantly lower using the McGrath Mac than the C-MAC-S or the C-MAC-S-PMVLs. Subjective appreciation of intubation difficulty and user-friendliness of the devices showed respectively lower and higher NRS scores for the McGrath-Mac compared to the other devices, whereas subjective assessment of image quality showed higher quality for the C-MAC-S and C-MAC-S-PM compared to the APA or McGrath-Mac. CONCLUSIONS: Among 4 single-use Macintosh-VLs, glottic visualization in direct and indirect laryngoscopy with the Macintosh-style blade was significantly improved with the McGrath-Mac compared to other Macintosh-VLs, leading to a less frequent need to resort to the hyperangulated blade and reduced overall number of intubation attempts.

PURPOSE: Single studies of video laryngoscopy (VL) use for airway management in intensive care unit (ICU) patients have produced controversial findings. The aim of this study was to critically review the literature to investigate whether VL reduces difficult orotracheal intubation (OTI) rate, first-attempt success, and complications related to intubation in ICU patients, compared to standard therapy, defined as direct laryngoscopy (DL). METHODS: We performed a systematic review and meta-analysis of randomized controlled trials, as well as prospective and retrospective observational studies, by searching PubMed, EMBASE, and bibliographies of articles retrieved. We screened for relevant studies that enrolled adults in whom the trachea was intubated in the ICU and compared VL to DL. We included studies reporting at least one clinical outcome of interest to perform a meta-analysis. We generated pooled odd ratios (OR) across studies. The primary outcome measure was difficult OTI. The secondary outcomes were first-attempt success, Cormack 3/4 grades, and complications related to intubation (severe hypoxemia, severe cardiovascular collapse, airway injury, esophageal intubation). RESULTS: Nine trials with a total of 2,133 participants (1,067 in DL and 1,066 in VL) were included in the current analysis. Compared to DL, VL reduced the risk of difficult OTI [OR 0.29 (95% confidence interval (CI) 0.20-0.44, p < 0.001)], Cormack 3/4 grades [OR 0.26 (95% CI 0.17-0.41, p < 0.001)], and esophageal intubation [0.14 (95% CI 0.02-0.81, p = 0.03)] and increased the first-attempt success [OR 2.07 (95% CI 1.35-3.16, p < 0.001)]. No statistically significant difference was found for severe hypoxemia, severe cardiovascular collapse or airway injury. CONCLUSIONS: These results suggest that VL could be useful in airway management of ICU patients.

PURPOSE: Airway management in intensive care unit (ICU) patients is challenging. The main objective of this study was to compare the incidence of difficult laryngoscopy and/or difficult intubation between a combo videolaryngoscope and the standard Macintosh laryngoscope in critically ill patients. METHODS: In the context of the implementation of a quality-improvement process for airway management, we performed a prospective interventional monocenter before-after study which evaluated a new combo videolaryngoscope. The primary outcome was the incidence of difficult laryngoscopy (defined by Cormack grade 3-4) and/or difficult intubation (more than two attempts). The secondary outcomes were the severe life-threatening complications related to intubation in ICU and the rate of difficult intubation in cases of predicted difficult intubation evaluated by a specific score (MACOCHA score ≥3). RESULTS: Two hundred and ten non-selected consecutive intubation procedures were included, 140 in the standard laryngoscope group and 70 in the combo videolaryngoscope group. The incidence of difficult laryngoscopy and/or difficult intubation was 16 % in the laryngoscope group vs. 4 % in the combo videolaryngoscope group (p = 0.01). The severe life-threatening complications related to intubation did not differ between groups (16 vs. 14 %, p = 0.79). Among the 32 patients with a MACOCHA score ≥3, there were significantly more patients with difficult intubation in the standard laryngoscope group in comparison to the combo videolaryngoscope group [12/23 (57 %) vs. 0/9 (0 %), p < 0.01]. CONCLUSIONS: The systematic use of a combo videolaryngoscope in ICU was associated with a decreased incidence of difficult laryngoscopy and/or difficult intubation.

BACKGROUND: Noninvasive positive-pressure ventilation (NPPV) with pressure support-ventilation and positive end-expiratory pressure are effective in providing oxygenation during intubation in hypoxemic patients. We hypothesized administration of oxygen (O2) using NPPV would more rapidly increase the end-tidal O2 concentration (ETO2) than preoxygenation using spontaneous ventilation (SV) in morbidly obese patients. METHODS: Twenty-eight morbidly obese patients were enrolled in this prospective randomized study. Administration of O2 for 5 min was performed either with SV group or with NPPV (pressure support = 8 cm H2O, positive end-expiratory pressure = 6 cm H2O) (NPPV group). ETO2 was measured using the anesthesia breathing circuit, and is expressed as a fraction of atmospheric concentration. The primary end-point was the number of patients with an ETo(2) >95% at the end of O2 administration. Secondary end-points included the time to reach the maximal ETO2 and the ETO2 at the conclusion of O2 administration. RESULTS: A larger proportion of patients achieved a 95% ETO2 at 5 min with NPPV than SV (13/14 vs 7/14, P = 0.01). The time to reach the maximal ETO2 was significantly less in the NPPV than in the SV group (185 +/- 46 vs 222 +/- 42 s, P = 0.02). The mean ETO2 at the conclusion of O2 administration was larger in the NPPV group than the SV group (96.9 +/- 1.3 vs 94.1 +/- 2.0%, P < 0.001). A modest, although significant, increase in gastric distension was observed in the NPPV group. No adverse effects were observed in either group. CONCLUSION: Administration of O2 via a facemask with NPPV in the operating room is safe, feasible, and efficient in morbidly obese patients. In this population NPPV provides a more rapid O2 administration, achieving a higher ETO2.

BACKGROUND: During the past few years, many manufacturers have introduced new modes of ventilation in anesthesia ventilators, especially partial-pressure modalities. The current bench test study was designed to compare triggering and pressurization of five new anesthesia ventilators with four intensive care unit ventilators. METHODS: Ventilators were connected to a two-compartment lung model. One compartment was driven by an intensive care unit ventilator to mimic "patient" inspiratory effort, whereas the other was connected to the tested ventilator. The settings of ventilators were positive end-expiratory pressures of 0 and 5 cm H2O, and pressure-support ventilation levels of 10, 15, and 20 cm H2O with normal and high "patient" inspiratory effort. For the anesthesia ventilators, all the measurements were obtained for a low (1 l/min) and a high (10 l/min) fresh gas flow. Triggering delay, triggering workload, and pressurization at 300 and 500 ms were analyzed. RESULTS: For the five tested anesthesia ventilators, the pressure-support ventilation modality functioned correctly. For inspiratory triggering, the three most recent anesthesia machines (Fabius, Drägerwerk AG, Lübeck, Germany; Primus, Drägerwerk AG; and Avance, GE-Datex-Ohemda, Munchen, Germany) had a triggering delay of less than 100 ms, which is considered clinically satisfactory and is comparable to intensive care unit machines. The use of positive end-expiratory pressure modified the quality of delivered pressure support for two anesthesia ventilators (Kion, Siemens AG, Munich, Germany; and Felix, Taema, Antony, France). Three of the five anesthesia ventilators exhibited pressure-support ventilation performance characteristics comparable to those of the intensive care unit machines. Increasing fresh gas flow (1 to 10 l/min) in the internal circuit did not influence the pressure-support ventilation performance of the anesthesia ventilators. CONCLUSION: Regarding trigger sensitivity and the system's ability to meet inspiratory flow during pressure-supported breaths, the most recent anesthesia ventilators have comparable performances of recent-generation intensive care unit ventilators.

BACKGROUND AND OBJECTIVES: As perioperative pain management is a difficult challenge during hemorrhoidectomy, we tested the hypothesis that posterior perineal block (PPB) with local anesthetics alone is able to provide adequate pain control during and after surgery. METHODS: In a prospective, blinded, randomized study, we studied analgesic conditions and side effects of PPB in American Society of Anesthesiologists (ASA) I-II patients undergoing hemorrhoidectomy. Patients received general anesthesia (GA) either with PPB (0.75% ropivacaine, 40 mL (PPB group) or without PPB (control group). All patients received intravenous morphine patient-controlled analgesia (PCA) for postoperative pain control (morphine, 1.5 mg-boluses, 8-minute lockout interval). Intra- and postoperative opioids consumption was recorded, and pain assessments were performed at 1, 2, 4, 8, 12, and 24 hours using a visual analog scale (VAS). RESULTS: VAS scores were significantly lower during the first 8 postoperative hours in the PPB group as compared with the control group (P <.001). The PPB group required significantly less opioids during anesthesia (P <.001) and during the first postoperative day (P <.001) as compared with the control group. Time to first defecation and duration of hospitalization were identical in both groups. CONCLUSIONS: The present study shows that PPB with 40 mL 0.75% ropivacaine (300 mg) was a simple, effective, and safe method to provide better postoperative analgesia than PCA alone following surgical hemorrhoidectomy. In addition, PPB was shown to significantly reduce opioid consumption intraoperatively and during the first postoperative day.

Postoperative patient-controlled analgesia provided by the intravenous route using morphine (PCA) or by the epidural route using an opioid in combination with a local anaesthetic (patient-controlled epidural analgesia; PCEA) is not yet routinely used in the elderly. However, this modality theoretically provides adequate control of postoperative pain in such patients. Firstly, an assessment of the level of pain is particularly difficult in the elderly, and patient-controlled techniques that enable the self-administration of analgesic could resolve this problem. Secondly, these techniques provide a fine and controlled titration of analgesic doses. Since analgesic-induced adverse effects increase with age, the risk of overdose is therefore reduced. Thirdly, effective postoperative patient-controlled analgesia may attenuate detrimental physiologic responses, and contribute to improvement in patient outcomes. In the elderly, PCEA provides better pain relief, particularly for dynamic pain, and improves postoperative recovery with a low incidence of adverse effects compared with PCA. PCA and PCEA techniques have a good safety profile in the elderly only when there is careful preoperative patient selection and strict postoperative monitoring. Standard observation of vital signs, sedation and pain scores and assessment of mental status are required. Patient selection is necessary to identify those patients who may be incapable of using the device (e.g. patients with evidence of cognitive dysfunction or physical disabilities). In addition, caution is required among patients with respiratory, renal or hepatic insufficiency. PCA and PCEA are particularly useful for elderly patients undergoing major thoraco-abdominal surgery. However, there is a need for further research in elderly patients. In the future, improvements in the management of postoperative pain in the elderly will lead to a greater expansion of self-controlled techniques.
