Neuromuscular blockade and airway management during endotracheal intubation in Brazilian intensive care units: a national survey.

ABSTRACT: OBJECTIVE:To describe the use of neuromuscular blockade as well as other practices among Brazilian physicians in adult intensive care units. METHODS:An online national survey was designed and administered to Brazilian intensivists. Questions were selected using the Delphi method and assessed physicians' demographic data, intensive care unit characteristics, practices regarding airway management, use of neuromuscular blockade and sedation during endotracheal intubation in the intensive care unit. As a secondary outcome, we applied a multivariate analysis to evaluate factors associated with the use of neuromuscular blockade. RESULTS:Five hundred sixty-five intensivists from all Brazilian regions responded to the questionnaire. The majority of respondents were male (65%), with a mean age of 38 ( 8.4 years, and 58.5% had a board certification in critical care. Only 40.7% of the intensivists reported the use of neuromuscular blockade during all or in more than 75% of endotracheal intubations. In the multivariate analysis, the number of intubations performed monthly and physician specialization in anesthesiology were directly associated with frequent use of neuromuscular blockade. Etomidate and ketamine were more commonly used in the clinical situation of hypotension and shock, while propofol and midazolam were more commonly prescribed in the situation of clinical stability. CONCLUSION:The reported use of neuromuscular blockade was low among intensivists, and sedative drugs were chosen in accordance with patient hemodynamic stability. These results may help the design of future studies regarding airway management in Brazil.

Project description:BACKGROUND:Point-of-care ultrasonography (POCUS) has recently become a useful tool that intensivists are incorporating into clinical practice. However, the incorporation of ultrasonography in critical care in developing countries is not straightforward. METHODS:Our objective was to investigate current practice and education regarding POCUS among Brazilian intensivists. A national survey was administered to Brazilian intensivists using an electronic questionnaire. Questions were selected by the Delphi method and assessed topics included organizational issues, POCUS technique and training patterns, machine availability, and main applications of POCUS in daily practice. RESULTS:Of 1533 intensivists who received the questionnaire, 322 responded from all of Brazil's regions. Two hundred and five (63.8%) reported having access to an ultrasound machine dedicated to the intensive care unit (ICU); however, this was more likely in university hospitals than in non-university hospitals (80.6 vs. 59.6%; risk ratio [RR]?=?1.35 [1.16-1.58], p?=?0.002). The main applications of POCUS were ultrasound-guided central vein catheterization (49.4%) and bedside echocardiographic assessment (33.9%). Two hundred and fifty-eight (80.0%) reported having at least one POCUS-trained intensivist in their staff (trained units). Trained units were more likely to perform routine ultrasound-guided jugular vein catheterization than non-trained units (38.6 vs. 16.4%; RR?=?2.35 [1.31-4.23], p?=?0.001). The proportion of POCUS-trained intensivists and availability of a dedicated ultrasound machine were both independently associated with performing ultrasound-guided jugular vein catheterization (RR?=?1.91 [1.32-2.77], p?=?0.001) and (RR?=?2.20 [1.26-3.29], p?=?0.005), respectively. CONCLUSIONS:A significant proportion of Brazilian ICUs had at least one intensivist with POCUS capability in their staff. Although ultrasound-guided central vein catheterization constitutes the main application of POCUS, adherence to guideline recommendations is still suboptimal.

Project description:BackgroundLidocaine (LDC) is a local anesthetic widely used to relieve intubation-related airway responses. However, low drug concentration and short effective duration of LDC is inadequate to provide a satisfactory anesthetic effect on the surface of the airway. The present study sought to develop a LDC-delivery endotracheal tube (ETT) to achieve high local drug concentration and sustained drug release with the aim of attenuating an intubation-related airway response.MethodsETTs and polyvinyl chloride (PVC) discs were coated with different molecular weight (MW) poly lactic-co-glycolic acid (PLGA: 50/50; MW: 3,000, 6,000, and 10,000) loaded with LDC by airbrush spray. The morphology of LDC-eluting coatings was analyzed using scanning electron microscopy. In vitro drug release was determined by ultraviolet spectrophotometer. An in vivo study was performed to investigate the differences in plasma LDC concentration, intubation tolerance, and tracheal tissue injury in rabbits undergoing intubation of blank, LDC-spray, or LDC-coated ETTs.ResultsApproximate 5 mg/cm2 coatings (containing 2.5 mg/cm2 LDC) were deposited onto the PVC discs and ETTs. While even distribution and smooth surfaces were generated in PLGA3000 + LDC and PLGA6000 + LDC coatings, PLGA10000 + LDC formed uneven and gullied coatings. Burst release within the first 4 h and sustained release for at least 5 days was achieved in vitro in PLGA + LDC coatings and the in vivo study demonstrated higher plasma LDC concentration and longer drug release duration in LDC-coated ETTs compared with LDC-spray. LDC-coated ETTs significantly improved intubation tolerance in rabbits, as measured by less general anesthetic consumption and longer tube tolerance duration in contrast to blank ETTs with or without LDC spray. Histology assessment showed less mucosal edema area in the PLGA3000 + LDC and PLGA6000 + LDC groups compared to the control, LDC-spray, and PLGA10000 + LDC groups. Among the different MW PLGAs, PLGA6000 presented optimal morphological characteristics, drug release, and anesthetic effect.ConclusionsETTs coated with PLGA + LDC effectively attenuate an intubation-related airway response via increasing local drug concentration and extending drug action duration, which demonstrates a potential therapeutic benefit for patients undergoing intubation.

Project description:BACKGROUND:Intubation is a lifesaving procedure that is often performed in intensive care unit (ICU) patients, but leads to serious adverse events in 20-40% of cases. Recent trials aimed to provide guidance about which medications, devices, and modalities maximize patient safety. Videolaryngoscopes are being offered in an increasing range of options and used in broadening indications (from difficult to unremarkable intubation). The objective of this study was to describe intubation practices and device availability in French ICUs. MATERIALS AND METHODS:We conducted an online nationwide survey by emailing an anonymous 26-item questionnaire to physicians in French ICUs. A single questionnaire was sent to either the head or the intubation expert at each ICU. RESULTS:Of 257 ICUs, 180 (70%) returned the completed questionnaire. The results showed that 43% of intubators were not fully proficient in intubation; among them, 18.8% had no intubation training or had received only basic training (lectures and observation at the bedside). Among the participating ICUs, 94.4% had a difficult intubation trolley, 74.5% an intubation protocol, 92.2% a capnography device (used routinely to check tube position in 69.3% of ICUs having the device), 91.6% a laryngeal mask, 97.2% front-of-neck access capabilities, and 76.6% a videolaryngoscope. In case of difficult intubation, 85.6% of ICUs used a bougie (154/180) and 7.8% switched to a videolaryngoscope (14/180). Use of a videolaryngoscope was reserved for difficult intubation in 84% of ICUs (154/180). Having a videolaryngoscope was significantly associated with having an intubation protocol (P = 0.043) and using capnography (P = 0.02). Airtraq® was the most often used videolaryngoscope (39.3%), followed by McGrath®Mac (36.9%) then by Glidescope® (14.5%). CONCLUSION:Nearly half the intubators in French ICUs are not fully proficient with OTI. Access to modern training methods such as simulation is inadequate. Most ICUs own a videolaryngoscope, but reserve it for difficult intubations.

Project description:BackgroundEmergency Department (ED) airway registries are formalized methods to collect and document airway practices and outcomes. Airway registries have become increasingly common in EDs globally; yet there is no consensus of airway registry methodology or intended utility. This review builds on previous literature and aims to provide a thorough description of international ED airway registries and discuss how airway registry data is utilized.MethodsA search of Medline, Embase, Scopus, Cochrane Libraries, Web of Science, and Google Scholar was performed with no date limitations applied. English language full-text publications and grey literature from centres implementing an ongoing airway registry to monitor intubations performed in mainly adult patients in an ED setting were included. Non-English publications and publications describing airway registries to monitor intubation practices in predominantly paediatric patients or settings outside of the ED were excluded. Study screening for eligibility was performed by two team members individually, with any disagreements resolved by a third team member. Data was charted using a standardized data charting tool created for this review.ResultsOur review identified 124 eligible studies from 22 airway registries with a global distribution. We found that airway registry data is used for quality assurance, quality improvement, and clinical research regarding intubation practices and contextual factors. This review also demonstrates that there is a great deal of heterogeneity in definitions of first-pass success and adverse events in the peri-intubation period.ConclusionsAirway registries are used as a crucial tool to monitor and improve intubation performance and patient care. ED airway registries inform and document the efficacy of quality improvement initiatives to improve intubation performance in EDs globally. Standardized definitions of first-pass success and peri-intubation adverse events, such as hypotension and hypoxia, may allow for airway management performance to be compared on a more equivalent basis and allow for the development of more reliable international benchmarks for first-pass success and rates of adverse events in the future.
