Critical Care Pharmacist Attitudes and Perceptions of Neuromuscular Blocker Infusions in ARDS.

BACKGROUND: Current critical care pharmacist (CCP) practices and perceptions related to neuromuscular infusion (NMBI) use for acute respiratory distress syndrome (ARDS) maybe different with the COVID-19 pandemic and the publication of 2020 NMBI practice guidelines. OBJECTIVE: To evaluate CCP practices and perceptions regarding NMBI use for patients with moderate-severe ARDS. METHODS: We developed, tested, and electronically administered a questionnaire (7 parent-, 42 sub-questions) to 409 American College of Clinical Pharmacy (ACCP) Critical Care Practice and Research Network members in 12 geographically diverse states. The questionnaire focused on adults with moderate-severe ARDS (PaO2:FiO2<150) whose causes of dyssynchrony were addressed. Two reminders were sent at 10-day intervals. RESULTS: Respondents [131/409 (32%)] primarily worked in a medical intensive care unit (ICU) 102 (78%). Compared to COVID-negative(-) ARDS patients, COVID positive(+) ARDS patients were twice as likely to receive a NMBI (34 ± 18 vs.16 ± 17%; P < 0.01). Respondents somewhat/strongly agreed a NMBI should be reserved until after trials of deep sedation (112, 86%) or proning (92, 81%) and that NMBI reduced barotrauma (88, 67%), dyssynchrony (87, 66%), and plateau pressure (79, 60%). Few respondents somewhat/strongly agreed that a NMBI should be initiated at ARDS onset (23, 18%) or that NMBI reduced 90-day mortality (12, 10%). Only 2/14 potential NMBI risks [paralysis awareness (101, 82%) and prolonged muscle weakness (84, 68%)] were frequently reported to be of high/very high concern. Multiple NMBI titration targets were assessed as very/extremely important including arterial pH (109, 88%), dyssynchrony (107, 86%), and PaO2: FiO2 ratio (82, 66%). Train-of-four (55, 44%) and BIS monitoring (36, 29%) were deemed less important. Preferred NMBI discontinuation criteria included absence of dysschrony (84, 69%) and use ≥48 hour (72, 59%). CONCLUSIONS AND RELEVANCE: Current critical care pharmacists believe NMBI for ARDS patients are best reserved until after trials of deep sedation or proning; unique considerations exist in COVID+ patients. Our results should be considered when ICU NMBI protocols are being developed and bedside decisions regarding NMBI use in ARDS are being formulated.

Physicians' attitudes and perceptions of neuromuscular blocker infusions in ARDS.

PURPOSE: The perceptions and practices of ICU physicians regarding initiating neuromuscular blocker infusions (NMBI) in acute respiratory distress syndrome (ARDS) may not be evidence-based amidst the surge of severe ARDS during the SARS-CoV-2 pandemic and new practice guidelines. We identified ICU physicians' perspectives and practices regarding NMBI use in adults with moderate-severe ARDS. MATERIALS AND METHODS: After extensive development and testing, an electronic survey was distributed to 342 ICU physicians from three geographically-diverse U.S. health systems(n = 12 hospitals). RESULTS: The 173/342 (50.5%) respondents (75% medical) somewhat/strongly agreed a NMBI should be reserved until: after a trial of deep sedation (142, 82%) or proning (59, 34%) and be dose-titrated based on train-of-four monitoring (107, 62%). Of 14 potential NMBI risks, 2 were frequently reported to be of high/very high concern: prolonged muscle weakness with steroid use (135, 79%) and paralysis awareness due to inadequate sedation (114, 67%). Absence of dyssychrony (93, 56%) and use ≥48 h (87, 53%) were preferred NMBI stopping criteria. COVID-19 + ARDS patients were twice as likely to receive a NMBI (56 ± 37 vs. 28 ± 19%, p < 0.01). CONCLUSIONS: Most intensivists agreed NMBI in ARDS should be reserved until after a deep sedation trial. Stopping criteria remain poorly defined. Unique considerations exist regarding the role of paralysis in COVID-19+ ARDS.

The Relationship of Obesity to Increasing Health-Care Burden in the Setting of Orthopaedic Polytrauma.

BACKGROUND: With the rise of obesity in the American population, there has been a proportionate increase of obesity in the trauma population. The purpose of this study was to use a computed tomography-based measurement of adiposity to determine if obesity is associated with an increased burden to the health-care system in patients with orthopaedic polytrauma. METHODS: A prospective comprehensive trauma database at a level-I trauma center was utilized to identify 301 patients with polytrauma who had orthopaedic injuries and intensive care unit admission from 2006 to 2011. Routine thoracoabdominal computed tomographic scans allowed for measurement of the truncal adiposity volume. The truncal three-dimensional reconstruction body mass index was calculated from the computed tomography-based volumes based on a previously validated algorithm. A truncal three-dimensional reconstruction body mass index of <30 kg/m(2) denoted non-obese patients and ≥ 30 kg/m(2) denoted obese patients. The need for orthopaedic surgical procedure, in-hospital mortality, length of stay, hospital charges, and discharge disposition were compared between the two groups. RESULTS: Of the 301 patients, 21.6% were classified as obese (truncal three-dimensional reconstruction body mass index of ≥ 30 kg/m(2)). Higher truncal three-dimensional reconstruction body mass index was associated with longer hospital length of stay (p = 0.02), more days spent in the intensive care unit (p = 0.03), more frequent discharge to a long-term care facility (p < 0.0002), higher rate of orthopaedic surgical intervention (p < 0.01), and increased total hospital charges (p < 0.001). CONCLUSIONS: Computed tomographic scans, routinely obtained at the time of admission, can be utilized to calculate truncal adiposity and to investigate the impact of obesity on patients with polytrauma. Obese patients were found to have higher total hospital charges, longer hospital stays, discharge to a continuing-care facility, and a higher rate of orthopaedic surgical intervention.

Single-site Nissen fundoplication versus laparoscopic Nissen fundoplication.

BACKGROUND: Advances in minimally invasive surgery have led to the emergence of single-incision laparoscopic surgery (SILS). The purpose of this study is to assess the feasibility of SILS Nissen fundoplication and compare its outcomes with traditional laparoscopic Nissen fundoplication. METHODS: This is a retrospective study of 33 patients who underwent Nissen fundoplication between January 2009 and September 2010. RESULTS: There were 15 SILS and 18 traditional laparoscopic Nissen fundoplication procedures performed. The mean operative time was 129 and 182 minutes in the traditional laparoscopic and single-incision groups, respectively (P=.019). There were no conversions in the traditional laparoscopic group, whereas 6 of the 15 patients in the SILS group required conversion by insertion of 2 to 4 additional ports (P=.0004). At short-term follow-up, recurrence rates were similar between both groups. To date, there have been no reoperations. CONCLUSIONS: SILS Nissen fundoplication is both safe and feasible. Short-term outcomes are comparable with standard laparoscopic Nissen fundoplication. Challenges related to the single-incision Nissen fundoplication include overcoming the lengthy learning curve and decreasing the need for additional trocars.

Single-incision laparoscopic Ladd's procedure for intestinal malrotation.

INTRODUCTION: The potential of single-incision laparoscopic surgery (SILS) as a less invasive and more cosmetically appealing technique has prompted the expansion of its adoption. SILS has been shown to be a safe and feasible alternative to traditional multiport cholecystectomy, appendectomy, colectomy, and many other laparoscopic procedures. The objective of this study is to provide an initial report of the feasibility of correcting intestinal malrotation via a single-incision laparoscopic transumbilical approach. CASE DESCRIPTION: A 29-year-old woman presented with symptomatic congenital intestinal malrotation. She elected to undergo a Ladd's procedure using a single-incision laparoscopic approach with a SILS port and standard laparoscopic instruments. The procedure was accomplished without additional ports or conversion to laparotomy, and no intraoperative or postoperative complications were noted. Total operative time was 106 minutes. The patient had minimal postoperative pain and was satisfied with the cosmetic outcome. CONCLUSION: When performed by a surgeon experienced in the SILS technique, single-incision laparoscopic Ladd's procedure for symptomatic intestinal malrotation in an adult is feasible and safe, with minimal postoperative pain and favorable cosmetic outcome.
