Improved COVID-19 Outcomes following Statin Therapy: An Updated Systematic Review and Meta-analysis.

BACKGROUND: Although vaccine rollout for COVID-19 has been effective in some countries, there is still an urgent need to reduce disease transmission and severity. We recently carried out a meta-analysis and found that pre- and in-hospital use of statins may improve COVID-19 mortality outcomes. Here, we provide an updated meta-analysis in an attempt to validate these results and increase the statistical power of these potentially important findings. METHODS: The meta-analysis investigated the effect of observational and randomized clinical studies on intensive care unit (ICU) admission, tracheal intubation, and death outcomes in COVID-19 cases involving statin treatment, by searching the scientific literature up to April 23, 2021. Statistical analysis and random effect modeling were performed to assess the combined effects of the updated and previous findings on the outcome measures. Findings. The updated literature search led to the identification of 23 additional studies on statin use in COVID-19 patients. Analysis of the combined studies (n = 47; 3,238,508 subjects) showed no significant effect of statin treatment on ICU admission and all-cause mortality but a significant reduction in tracheal intubation (OR = 0.73, 95% CI: 0.54-0.99, p = 0.04, n = 10 studies). The further analysis showed that death outcomes were significantly reduced in the patients who received statins during hospitalization (OR = 0.54, 95% CI: 0.50-0.58, p < 0.001, n = 7 studies), with no such effect of statin therapy before hospital admission (OR = 1.06, 95% CI = 0.82-1.37, p = 0.670, n = 29 studies). CONCLUSION: Taken together, this updated meta-analysis extends and confirms the findings of our previous study, suggesting that in-hospital statin use leads to significant reduction of all-cause mortality in COVID-19 cases. Considering these results, statin therapy during hospitalization, while indicated, should be recommended.

In-vitro and in-vivo comparisons of high versus low concentrations of inhaled epoprostenol to adult intubated patients.

BACKGROUND: Inhaled epoprostenol (iEPO) has been shown to reduce pulmonary artery pressure and improve oxygenation. iEPO is mainly delivered via a syringe pump with feed tubing connected to a vibrating mesh nebulizer with high or low formulation concentration delivery. METHODS: An in vitro study and a two-period retrospective case-control study were implemented. The in vitro study compared iEPO delivery via invasive ventilation at low concentrations of 7.5, and 15 mcg/mL and high concentration at 30 mcg/mL, to deliver the ordered dose of 30 and 50 ng/kg/min for three clinical scenarios with predicted body weight of 50, 70 and 90 kg. While in the clinical study, adult patients receiving iEPO via invasive ventilation to treat refractory hypoxemia, pulmonary hypertension, or right ventricular failure were included. 80 patients received low concentration iEPO at multiple concentrations (2.5, 7.5, and 15 mcg/mL, depending on the ordered dose) from 2015 to 2017, while 84 patients received high concentration iEPO at 30 mcg/mL from 2018 to 2019. RESULTS: In the in vitro study, there were no significant differences in aerosol deposition between high vs low concentrations of iEPO at a dose of 50 ng/kg/min. In the clinical study, age, gender, ethnicity, and indications for iEPO were similar between high and low concentration groups. After 30-120 min of iEPO administration, both delivery strategies significantly improved oxygenation in hypoxemic patients and reduced mean pulmonary arterial pressure (mPAP) for patients with pulmonary hypertension. However, no significant differences of the incremental changes were found between two delivery groups. Compared to low concentration, high concentration delivery group had better adherence to the iEPO weaning protocol (96% vs 71%, p < 0.001), fewer iEPO syringes utilized per patient (5 [3, 10] vs 12 [6, 22], p = 0.001), and shorter duration of invasive ventilation (6 [3, 12] vs 9 [5, 18] days, p = 0.028). Intensive care unit length of stay and mortality were similar between two groups. CONCLUSION: Compared to low concentration delivery of iEPO, high concentration iEPO via a vibrating mesh nebulizer maintained clinical benefits and increased clinician compliance with an iEPO weaning protocol, required less medication preparation time, and shortened duration of invasive ventilation.

International Survey of Mechanical Thrombectomy Stroke Systems of Care During COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic has strained the healthcare systems across the world but its impact on acute stroke care is just being elucidated. We hypothesized a major global impact of COVID-19 not only on stroke volumes but also on various aspects of thrombectomy systems. AIMS: We conducted a convenience electronic survey with a 21-item questionnaire aimed to identify the changes in stroke admission volumes and thrombectomy treatment practices seen during a specified time period of the COVID-19 pandemic. METHODS: The survey was designed using Qualtrics software and sent to stroke and neuro-interventional physicians around the world who are part of the Global Executive Committee (GEC) of Mission Thrombectomy 2020, a global coalition under the aegis of Society of Vascular and Interventional Neurology, between April 5th and May 15th, 2020. RESULTS: There were 113 responses to the survey across 25 countries with a response rate of 31% among the GEC members. Globally there was a median 33% decrease in stroke admissions and a 25% decrease in mechanical thrombectomy (MT) procedures during the COVID-19 pandemic period until May 15th, 2020 compared to pre-pandemic months. The intubation policy for MT procedures during the pandemic was highly variable across participating centers: 44% preferred intubating all patients, including 25% of centers that changed their policy to preferred-intubation (PI) from preferred non-intubation (PNI). On the other hand, 56% centers preferred not intubating patients undergoing MT, which included 27% centers that changed their policy from PI to PNI. There was no significant difference in rate of COVID-19 infection between PI versus PNI centers (p=0.60) or if intubation policy was changed in either direction (p=1.00). Low-volume (<10 stroke/month) compared with high-volume stroke centers (>20 strokes/month) were less likely to have neurointerventional suite specific written personal protective equipment protocols (74% vs 88%) and if present, these centers were more likely to report them to be inadequate (58% vs 92%). CONCLUSION: Our data provides a comprehensive snapshot of the impact on acute stroke care observed worldwide during the pandemic. Overall, respondents reported decreased stroke admissions as well as decreased cases of MT with no clear preponderance in intubation policy during MT. DATA ACCESS STATEMENT: The corresponding author will consider requests for sharing survey data. The study was exempt from institutional review board approval as it did not involve patient level data.

Association Between FIASMAs and Reduced Risk of Intubation or Death in Individuals Hospitalized for Severe COVID-19: An Observational Multicenter Study.

Several medications commonly used for a number of medical conditions share a property of functional inhibition of acid sphingomyelinase (ASM), or FIASMA. Preclinical and clinical evidence suggest that the ASM/ceramide system may be central to severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection. We examined the potential usefulness of FIASMA use among patients hospitalized for severe coronavirus disease 2019 (COVID-19) in an observational multicenter study conducted at Greater Paris University hospitals. Of 2,846 adult patients hospitalized for severe COVID-19, 277 (9.7%) were taking an FIASMA medication at the time of their hospital admission. The primary end point was a composite of intubation and/or death. We compared this end point between patients taking vs. not taking an FIASMA medication in time-to-event analyses adjusted for sociodemographic characteristics and medical comorbidities. The primary analysis was a Cox regression model with inverse probability weighting (IPW). Over a mean follow-up of 9.2 days (SD = 12.5), the primary end point occurred in 104 patients (37.5%) receiving an FIASMA medication, and 1,060 patients (41.4%) who did not. Despite being significantly and substantially associated with older age and greater medical severity, FIASMA medication use was significantly associated with reduced likelihood of intubation or death in both crude (hazard ratio (HR) = 0.71, 95% confidence interval (CI) = 0.58-0.87, P < 0.001) and primary IPW (HR = 0.58, 95%CI = 0.46-0.72, P < 0.001) analyses. This association remained significant in multiple sensitivity analyses and was not specific to one particular FIASMA class or medication. These results show the potential importance of the ASM/ceramide system in COVID-19 and support the continuation of FIASMA medications in these patients. Double-blind controlled randomized clinical trials of these medications for COVID-19 are needed.

Early Neurologic Recovery, Practice Pattern Variation, and the Risk of Endotracheal Intubation Following Established Status Epilepticus.

OBJECTIVE: To quantify the association between early neurologic recovery, practice pattern variation, and endotracheal intubation during established status epilepticus, we performed a secondary analysis within the cohort of patients enrolled in the Established Status Epilepticus Treatment Trial (ESETT). METHODS: We evaluated factors associated with the endpoint of endotracheal intubation occurring within 120 minutes of ESETT study drug initiation. We defined a blocked, stepwise multivariate regression, examining 4 phases during status epilepticus management: (1) baseline characteristics, (2) acute treatment, (3) 20-minute neurologic recovery, and (4) 60-minute recovery, including seizure cessation and improving responsiveness. RESULTS: Of 478 patients, 117 (24.5%) were intubated within 120 minutes. Among high-enrolling sites, intubation rates ranged from 4% to 32% at pediatric sites and 19% to 39% at adult sites. Baseline characteristics, including seizure precipitant, benzodiazepine dosing, and admission vital signs, provided limited discrimination for predicting intubation (area under the curve [AUC] 0.63). However, treatment at sites with an intubation rate in the highest (vs lowest) quartile strongly predicted endotracheal intubation independently of other treatment variables (adjusted odds ratio [aOR] 8.12, 95% confidence interval [CI] 3.08-21.4, model AUC 0.70). Site-specific variation was the factor most strongly associated with endotracheal intubation after adjustment for 20-minute (aOR 23.4, 95% CI 6.99-78.3, model AUC 0.88) and 60-minute (aOR 14.7, 95% CI 3.20-67.5, model AUC 0.98) neurologic recovery. CONCLUSIONS: Endotracheal intubation after established status epilepticus is strongly associated with site-specific practice pattern variation, independently of baseline characteristics, and early neurologic recovery and should not alone serve as a clinical trial endpoint in established status epilepticus.

Comparative Efficacy of 6 Topical Pharmacological Agents for Preventive Interventions of Postoperative Sore Throat After Tracheal Intubation: A Systematic Review and Network Meta-analysis.

BACKGROUND: Topical pharmacological agents typically used to treat postoperative sore throat (POST) after tracheal intubation include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, lidocaine, Glycyrrhiza (licorice), and N-methyl-d-aspartate (NMDA) receptor antagonists (including ketamine and magnesium). However, the optimal prophylactic drug remains elusive. METHODS: The literature published before September 8, 2019 was searched on the PubMed, the Embase, the Web of Science, and the Cochrane Library. Randomized controlled trials (RCTs) covering topical prophylactic medications for patients with POST were included. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the quality of evidence. The primary outcome is the risk of POST. Combining both direct and indirect evidence, a network meta-analysis was performed to assess odds ratios (ORs) between the topical pharmacological agents and surface under the cumulative ranking (SUCRA) curve for the treatment-based outcomes. This study is registered with PROSPERO, number CRD42020158985. RESULTS: Sixty-two RCTs (at least 73% of which were double blinded) that included a total of 6708 subjects and compared 6 categories of drugs and/or placebos were ultimately enrolled. All preventive interventions except lidocaine were more effective than placebo at the 4 time intervals. Lidocaine (OR: 0.35, 95% credible interval [CrI], 0.16-0.79) has a greater POST preventative intervention effect than the placebo at a time interval of only 2 to 3 hours after surgery. Relative to lidocaine, the risk of POST except 2 to 3 hours was lower for the following treatments: corticosteroids, ketamine, magnesium, NSAIDs, and Glycyrrhiza. The NMDA receptor antagonists studied here included ketamine and magnesium. Magnesium generally demonstrated greater benefit than ketamine at 24 hours postsurgery/extubation (OR: 0.41, 95% CrI, 0.18-0.92). Compared with ketamine, corticosteroids were associated with a reduced risk of POST during the 4 to 6 hours (OR: 0.40, 95% CrI, 0.19-0.83) and 24 hours (OR: 0.34, 95% CrI, 0.16-0.72) time intervals. During the 2 to 3 hours time interval, Glycyrrhiza (OR: 0.38, 95% CrI, 0.15-0.97) was more efficacious than magnesium. CONCLUSIONS: Our analysis shows that, among the 6 topical medications studied, lidocaine is not optimal for topical use to prevent POST. Glycyrrhizin, corticosteroids, NSAIDs, and NMDA receptor antagonists (ketamine and magnesium) are associated with a reduced postoperative pharyngeal pain across the 4 postsurgical time intervals studied, all of which can be chosen according to the clinical experience of the anesthesiologists and the patient preferences and are recommended for the reduction of postoperative throat pain.

The impact of tracheostomy timing on clinical outcomes and adverse events in intubated patients with infratentorial lesions: early versus late tracheostomy.

We evaluated the association between the timing of tracheostomy and clinical outcomes in patients with infratentorial lesions. We performed a retrospective observational cohort study in a neurosurgical intensive care unit (ICU) at a tertiary academic medical center from January 2014 to December 2018. Consecutive adult patients admitted to the ICU who underwent resection of infratentorial lesions as well as tracheostomy were included for analysis. Early tracheostomy was defined as performed on postoperative days 1-10 and late tracheostomy on days 10-20 after operation. Univariate and multivariate analyses were used to compare the characteristics and outcomes between both cohorts. A total of 143 patients were identified, and 96 patients received early tracheostomy. Multivariable analysis identified early tracheostomy as an independent variable associated with lower occurrence of pneumonia (odds ratio, 0.25; 95% CI, 0.09-0.73; p = 0.011), shorter stays in ICUs (hazard ratio, 0.4; 95% CI, 0.3-0.6; p = 0.03), and earlier decannulation (hazard ratio, 0.5; 95% CI, 0.4-0.8; p = 0.003). However, no significant differences were observed between the early and late tracheostomy groups regarding hospital mortality (p > 0.999) and the modified Rankin scale after 6 months (p = 0.543). We also identified postoperative brainstem deficits, including cough, swallowing attempts, and extended tongue as well as GCS < 8 at ICU admission as the risk factors independently associated with patients underwent tracheostomy. There is a significant association between early tracheostomy and beneficial clinical outcomes or reduced adverse event occurrence in patients with infratentorial lesions.

The case for a 3rd generation supraglottic airway device facilitating direct vision placement.

Although 1st and 2nd generation supraglottic airway devices (SADs) have many desirable features, they are nevertheless inserted in a similar 'blind' way as their 1st generation predecessors. Clinicians mostly still rely entirely on subjective indirect assessments to estimate correct placement which supposedly ensures a tight seal. Malpositioning and potential airway compromise occurs in more than half of placements. Vision-guided insertion can improve placement. In this article we propose the development of a 3rd generation supraglottic airway device, equipped with cameras and fiberoptic illumination, to visualise insertion of the device, enable immediate manoeuvres to optimise SAD position, verify whether correct 1st and 2nd seals are achieved and check whether size selected is appropriate. We do not provide technical details of such a '3rd generation' device, but rather present a theoretical analysis of its desirable properties, which are essential to overcome the remaining limitations of current 1st and 2nd generation devices. We also recommend that this further milestone improvement, i.e. ability to place the SAD accurately under direct vision, be eligible for the moniker '3rd generation'. Blind insertion of SADs should become the exception and we anticipate, as in other domains such as central venous cannulation and nerve block insertions, vision-guided placement becoming the gold standard.

Use of an Ultra-slim Gastroscope to Accomplish Endoscopist-Facilitated Rescue Intubation During ERCP: A Novel Approach to Enhance Patient and Staff Safety.

BACKGROUND: ERCP is often performed under monitored anesthesia care (MAC) rather than general anesthesia (GA), with patients positioned semi-prone on the fluoroscopy table. Rarely, a MAC ERCP must be converted to GA due to hypoxia or retained food in the stomach. In these circumstances, standard intubation is associated with a significant delay and potential for patient/staff injury during repositioning. We report a novel endoscopist-driven approach to intubation during ERCP using an ultra-slim, flexible gastroscope with an endotracheal tube backloaded onto it. MATERIALS AND METHODS: We identified patients who underwent ERCP from 2014 to 2019, and MAC to GA conversion events. Mode of intubation (standard vs. endoscopist-facilitated) and patient/procedure characteristics were evaluated. All endoscopist-facilitated intubations were performed under anesthesiologist supervision. RESULTS: A total of 3409 patients underwent ERCP; 1568 (46%) GA and 1841 (54%) MAC. Of these, 42 (2.3%) required intubation during ERCP and 16 underwent endoscopist-facilitated intubation due to retained food in the stomach and/or hypoxia. In 3 patients, aspirated material was suctioned from the trachea and bronchi using the ultra-slim gastroscope. Immediate post-procedure extubation was successful in all endoscopist-facilitated intubation patients and none exhibited radiographic evidence of aspiration pneumonia. CONCLUSIONS: Endoscopist-facilitated intubation using an ultra-slim flexible gastroscope is feasible and expeditious for MAC to GA conversion during ERCP. This technique is readily accomplished in the semi-prone position, while standard intubation requires patient transfer from fluoroscopy table to gurney, with associated delay/risks. These data suggest that further study of this approach is warranted, and this may be the most favorable approach for intubation during ERCP.

Evaluation of Benefit and Cost Utility of Immediate Postanesthesia Care Unit Radiographs to Predict Airway Compromise After Anterior Cervical Discectomy and Fusion.

STUDY DESIGN: Retrospective review. OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is a commonly performed procedure that may be complicated by airway compromise postoperatively. This life-threatening complication may necessitate reintubation and reoperation. We evaluated the cost utility of conventional postoperative x-ray. SUMMARY OF BACKGROUND DATA: Studies have demonstrated minimal benefit in obtaining an x-ray on postoperative day 1, but there is some utility of postanesthesia care unit (PACU) x-rays for predicting the likelihood of reoperation. METHODS: We retrospectively reviewed the records of consecutive patients who underwent ACDF between September 2013 and February 2017. Patients were dichotomized into those who received PACU x-rays and those who did not (control group). Primary outcomes were reoperation, reintubation, mortality, and health care costs. RESULTS: Eight-hundred and fifteen patients were included in our analysis: 558 had PACU x-rays; 257 did not. In those who received PACU x-rays, mean age was 53.7 ±â€Š11.3 years, mean levels operated on were 2.0 ±â€Š0.79, and mean body mass index (BMI) was 30.3 ±â€Š6.9. In those who did not, mean age was 51.8 ±â€Š10.9 years, mean levels operated on were 1.48 ±â€Š0.65, and mean BMI was 29.9 ±â€Š6.3. Complications in the PACU x-ray group were reintubation-0.4%, reoperation-0.7%, and death-0.3% (due to prevertebral swelling causing airway compromise). Complications in the control group were reintubation-0.4%, reoperation-0.8%, and death-0. There were no differences between groups with respect to reoperation (P = 0.92), reintubation (P = 0.94), or mortality (P = 0.49). The mean per-patient cost was significantly higher (P = 0.009) in those who received PACU x-rays, $1031.76 ±â€Š948.67, versus those in the control group, $700.26 ±â€Š634.48. Mean length of stay was significantly longer in those who had PACU x-rays (P = 0.01). CONCLUSION: Although there were no differences in reoperation, reintubation, or mortality, there was a significantly higher cost for care and hospitalization in those who received PACU x-rays. Further studies are warranted to validate the results of the presented study.Level of Evidence: 3.

A call for collaboration and consensus on training for endotracheal intubation in the medical intensive care unit.

Endotracheal intubation (EI) is a potentially lifesaving but high-risk procedure in critically ill patients. While the ACGME mandates that trainees in pulmonary and critical care medicine (PCCM) achieve competence in this procedure, there is wide variation in EI training across the USA. One study suggests that 40% of the US PCCM trainees feel they would not be proficient in EI upon graduation. This article presents a review of the EI training literature; the recommendations of a national group of PCCM, anesthesiology, emergency medicine, and pediatric experts; and a call for further research, collaboration, and consensus guidelines.

The effects of labor on airway outcomes with Supreme™ laryngeal mask in women undergoing cesarean delivery under general anesthesia: a cohort study.

BACKGROUND: Pregnancy is associated with higher incidence of failed endotracheal intubation and is exacerbated by labor. However, the influence of labor on airway outcomes with laryngeal mask airway (LMA) for cesarean delivery is unknown. METHODS: This is a secondary analysis of a prospective cohort study on LMA use during cesarean delivery. Healthy parturients who fasted > 4 h undergoing Category 2 or 3 cesarean delivery with Supreme™ LMA (sLMA) under general anesthesia were included. We excluded parturients with BMI > 35 kg/m2, gastroesophageal reflux disease, or potentially difficult airway (Mallampati score of 4, upper respiratory tract or neck pathology). Anesthesia and airway management reflected clinical standard at the study center. After rapid sequence induction and cricoid pressure, sLMA was inserted as per manufacturer's recommendations. Our primary outcome was time to effective ventilation (time from when sLMA was picked up until appearance of end-tidal carbon dioxide capnography), and secondary outcomes include first-attempt insertion failure, oxygen saturation, ventilation parameters, mucosal trauma, pulmonary aspiration, and Apgar scores. Differences between labor status were tested using Student's t-test, Mann-Whitney U test, or Fisher's exact test, as appropriate. Quantitative associations between labor status and outcomes were determined using univariate logistic regression analysis. RESULTS: Data from 584 parturients were analyzed, with 37.8% in labor. Labor did not significantly affect time to effective ventilation (mean (SD) for labor: 16.0 (5.75) seconds; no labor: 15.3 (3.35); mean difference: -0.65 (95%CI: - 1.49 to 0.18); p = 0.1262). However, labor was associated with increased first-attempt insertion failure and blood on sLMA surface. No reduction in oxygen saturation or pulmonary aspiration was noted. CONCLUSIONS: Although no significant increase in time to effective ventilation was noted, labor may increase the number of insertion attempts and oropharyngeal trauma with sLMA use for cesarean delivery in parturients at low risk of difficult airway. Future studies should investigate the effects of labor on LMA use in high risk parturients. TRIAL REGISTRATION: The study was prospectively registered at clinicaltrials.gov ( NCT02026882 ) on 3 January 2014.

Complications of cricothyroidotomy versus tracheostomy in emergency surgical airway management: a systematic review.

BACKGROUND: Airway guidelines recommend an emergency surgical airway as a potential life-saving treatment in a "Can't Intubate, Can't Oxygenate" (CICO) situation. Surgical airways can be achieved either through a cricothyroidotomy or tracheostomy. The current literature has limited data regarding complications of cricothyroidotomy and tracheostomy in an emergency situation. The objective of this systematic review is to analyze complications following cricothyroidotomy and tracheostomy in airway emergencies. METHODS: This synthesis of literature was exempt from ethics approval. Eight databases were searched from inception to October 2018, using a comprehensive search strategy. Studies were included if they were randomized controlled trials or observational studies reporting complications following emergency surgical airway. Complications were classified as minor (evolving to spontaneous remission or not requiring intervention or not persisting chronically), major (requiring intervention or persisting chronically), early (from the start of the procedure up to 7 days) and late (beyond 7 days of the procedure). RESULTS: We retrieved 2659 references from our search criteria. Following the removal of duplicates, title and abstract review, 33 articles were selected for full-text reading. Twenty-one articles were finally included in the systematic review. We found no differences in minor, major or early complications between the two techniques. However, late complications were significantly more frequent in the tracheostomy group [OR (95% CI) 0.21 (0.20-0.22), p < 0.0001]. CONCLUSIONS: Our results demonstrate that cricothyroidotomies performed in emergent situations resulted in fewer late complications than tracheostomies. This finding supports the recommendations from the latest Difficult Airway Society (DAS) guidelines regarding using cricothyroidotomy as the technique of choice for emergency surgical airway. However, emergency cricothyroidotomies should be converted to tracheostomies in a timely fashion as there is insufficient evidence to suggest that emergency cricothyrotomies are long term airways.

Impact of the Revised NRP Meconium Aspiration Guidelines on Term Infant Outcomes.

OBJECTIVES: To evaluate the association of the Neonatal Resuscitation Program, Seventh Edition changes on term infants born with meconium-stained amniotic fluid (MSAF). STUDY DESIGN: We evaluated the effect of no longer routinely intubating nonvigorous term infants born with MSAF in 14 322 infants seen by the resuscitation team from January 1, 2014 to June 30, 2017 in a large, urban, academic hospital. RESULTS: Delivery room intubations of term infants with MSAF fell from 19% to 3% after the change in guidelines (P = <.0001). The rate of all other delivery room intubations also decreased by 3%. After the implementation of the Seventh Edition guidelines, 1-minute Apgar scores were significantly more likely to be >3 (P = .009) and significantly less likely to be <7 (P = .011). The need for continued respiratory support after the first day of life also decreased. Admission rates to the NICU, length of stay, and the need for respiratory support on admission were unchanged. CONCLUSIONS: Implementation of the Neonatal Resuscitation Program, Seventh Edition recommendations against routine suctioning nonvigorous infants born with MSAF was temporally associated with an improvement in 1-minute Apgar scores and decreased the need for respiratory support after the first day of life. There was also a significant decrease in total intubations performed in the delivery room. This has long-term implications on intubation experience among frontline providers.

Risk factors and associated complications with unplanned intubation in patients with craniotomy for brain tumor.

Patients undergoing surgical resection of a brain tumor have the potential risk for beingintubated post-operatively, which may be associated with significant morbidity and/or mortality after surgery. This study was analyzed various preoperative patient characteristics, postoperative outcomes, and complications to identify risk factors for unplanned intubation (UI) in adult patients undergoing craniotomy for a brain tumor and created a risk score framework for that cohort. Patients undergoing surgery for a brain tumor were identified according to primary Current Procedural Terminology codes, and information found in The American College of Surgeons (ACS) National Surgical Quality Improvement Project (NSQIP) database from 2012 to 2015 was reviewed. A total of 18,642 adult brain tumor patients were included in the ACS-NSQIP. The rate of unplanned intubation in this cohort was 2.30% (4 2 8). The mortality rate of patients who underwent UI after surgical resection of brain tumor was 24.78% compared to an overall mortality of 2.46%. During the first 30 days after surgery, 33% of patients who underwent UI had an unplanned reoperation, compared to 4.76% of patients who did not undergo unplanned intubation. Bivariate and multivariate analyses identified several predictors and computed a risk score for UI. A risk score based on patient factors for those undergoing a craniotomy for a brain tumor predicts the postoperative UI rate. This could aid in surgical decision-making by identify patients at a higher risk of UI, while modifying perioperative management may help prevent UI.

Effects of Preoperative Gum Chewing on Sore Throat After General Anesthesia With a Supraglottic Airway Device: A Randomized Controlled Trial.

BACKGROUND: Postoperative sore throat (POST) is not uncommon after general anesthesia with a supraglottic airway (SGA) device. Although it was reported that some pharmacological and nonpharmacological measures can reduce POST, because of limitations and variable success rates, we need to find a simpler and more effective way to alleviate POST. METHODS: This prospective, observer-blinded, randomized controlled study enrolled 140 patients who required general anesthesia administered via a streamlined liner of the pharyngeal airway (SLIPA) for <60 minutes. They were randomly divided into the gum (group G, n = 70) and control (group C, n = 70) groups. Before the induction of general anesthesia for 5-10 minutes, the patients in group G chewed gum for 2 minutes. Group C was asked to swallow twice without any additional treatment. A standard anesthesia protocol was followed. The incidence and severity of sore throat were assessed up to 24 hours postoperatively. The primary outcome was the incidence of POST numerical rating scale (NRS) scores >3 within 24 hours after surgery, and the secondary outcomes included the POST (NRS) scores 2, 6, and 24 hours after the surgery. RESULTS: The incidence of moderate/severe POST (NRS >3) within 24 hours after surgery was significantly lower in group G (10.1%, 7/69) than in group C (40.6%, 28/69) (odds ratio 0.386, 95% confidence interval [CI], 0.153-0.976; P = .044). The median (interquartile range [range]) scores at 2, 6, and 24 hours after anesthesia in group G were lower than those in the control group at the same times (2 hours: 0 [0-3 {0-4}] vs 3 [0-3 {0-6}], P = .048; 6 hours: 0 [0-3 {0-6}] vs 2 [0-4 {0-6}], P = .048; 24 hours: 0 [0-1 {0-7}] vs 0 [0-2 {0-6}]; P = .011). There were 14 patients (20.3%, 14/69) in group G who had blood stains on the SGA device, which was significantly lower than the number in group C (37.7%, 26/69) (P = .024). In patients with bloody SGA devices, the incidence of POST scores >3 was significantly lower in group G (14.3%, 2/14) than in group C (73.1%, 19/26) (P < .001), while there was no significant difference between the 2 groups in the incidence of POST score >3 in patients without bloody SGA devices (group G: 9.1%, 5/55; group C: 20.9%, 9/43; P = .145). CONCLUSIONS: Chewing gum before surgery can effectively reduce POST with a SGA device for hysteroscopic surgery, especially in patients with pharyngeal mucosal injury.

Comparison of Neonatal Intubation Practice and Outcomes between the Neonatal Intensive Care Unit and Delivery Room.

BACKGROUND: Characteristics of neonatal tracheal intubations (TI) may vary between the neonatal intensive care unit (NICU) and delivery room (DR). The impact of the setting on TI outcomes is not well characterized. OBJECTIVE: The aim of this study was to define variation in neonatal TI practice between settings, and identify the association between setting and TI success and safety outcomes. DESIGN: This was a retrospective cohort study of TIs in the National Emergency Airway Registry for Neonates from October 2014 to September 2017. The setting (NICU vs. DR) was the exposure of interest. The outcomes were first attempt success, course success, success within 4 attempts, adverse TI-associated events, severe desaturation, and bradycardia. We compared TI characteristics and outcomes between settings in univariable analysis. Factors significant in univariable analysis (p < 0.1) were included in a logistic regression model, with adjustment for clustering by center, to identify the independent impact of the setting on TI outcomes. RESULTS: There were 3,145 TI encounters (2279 NICU, 866 DR) in 9 centers. Almost all baseline characteristics significantly varied between settings. First attempt success rates were 48% (NICU) and 46% (DR). In multivariable analysis, the setting was not associated with first attempt success. DR was associated with a higher adjusted OR (aOR) of success within 4 attempts (1.48, 95% CI 1.06-2.08) and a lower aOR for bradycardia (0.43, 95% CI 0.26-0.71). CONCLUSION: Significant differences in patient, provider, and practice characteristics exist between NICU and DR TIs. There is substantial room for improvement in first attempt success rates. These results suggest interventions to improve safety and success need to be targeted to the distinct setting.

Change in neonatal resuscitation guidelines and trends in incidence of meconium aspiration syndrome in California.

OBJECTIVE: To describe trends in the incidence and severity of meconium aspiration syndrome (MAS) around the release of revised Neonatal Resuscitation Program (NRP) guidelines in 2016. STUDY DESIGN: The California Perinatal Quality Care Collaborative database was queried for years 2013-2017 to describe the incidence and outcomes of infants with MAS. Results were analyzed based on both individual years and pre- vs. post-guideline epochs (2013-15 vs. 2017). RESULT: Incidence of MAS decreased significantly from 2013-15 to 2017 (1.02 to 0.78/1000 births, p < 0.001). Among infants with MAS, delivery room intubations decreased from 2013-15 to 2017 (44.3 vs. 35.1%; p = 0.005), but similar proportion of infants required invasive respiratory support (80.1 vs. 80.8%), inhaled nitric oxide (28.8 vs. 28.4%) or extracorporeal membrane oxygenation (0.81 vs. 0.35%). CONCLUSION: While the study design precludes confirmation of implementation of the recent NRP recommendation, there was no increase in the incidence or severity of MAS following its release.
