Background: Tracheal intubation is an important clinical skill for medical students and junior residents (novice intubators). They are usually trained to use a direct laryngoscope (DL) with straight-to-cuff styletted tracheal tubes first. Only later are they exposed to the bougie as an airway adjunct and videolaryngoscope (VL) with either a standard blade or a hyperangulated blade. The purpose of this study was to investigate the performance of novice intubators in using DL with 3 common stylets., Methods: We conducted a prospective study to compare the performance of DL with 3 common stylets, namely the straight-to-cuff stylet (S), hyperangulated VL stylet (G), and bougie (B), on a manikin model., Results: Among 72 participants, no significant difference was observed between the success rates of S, G, and B at the first attempt (84.72%, 81.94%, and 86.11%, respectively [P = .78]) or within 2 minutes (91.67%, 93.06%, and 91.67%, respectively [P = .94]). For participants with successful intubation within 2 minutes, the average total intubation times for S, G, and B were 25.05, 24.39, and 37.45 seconds, respectively. Among the 3 stylets, B had the longest intubation time, which differed significantly from S and G (P < .01)., Conclusions: The performances of novice intubators with 3 different stylets were similar. The success rates for DL with either hyperangulated VL stylet or bougie were not inferior compared with the straight-to-cuff stylet on manikin airway training model. If we properly trained novice intubators to use corresponding maneuvers, they can learn to use the 3 stylets early in their airway learning course., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2022 the Author(s).

Rationale: Postpartum ovarian vein thrombophlebitis (POVT) is a rare condition, and it can lead to severe complications and mortality. Here we report a patient who presented with vaginal bleeding and the diagnosis of POVT was confirmed by imaging., Patient Concerns: A 38-year-old postpartum woman without remarkable medical history presented with vaginal bleeding and lower abdominal pain., Diagnoses: The diagnosis was confirmed by computed tomography scan marked by a thrombus mass involving the right ovarian vein and inferior vena cava., Interventions: The patient was treated with intravenous antibiotics and low-molecular-weight heparin., Outcomes: The patient recovered smoothly without complications., Lessons: We should pay high attention to the recognition and management of POVT to prevent morbidity and mortality., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

This study demonstrated a training program of the suction-assisted laryngoscopy assisted decontamination (S.A.L.A.D.) technique for emergency medical technician paramedic (EMT-P). The effectiveness of the training program on the improvements of skills and confidence in managing soiled airway was evaluated.In this pilot before-after study, 41 EMT-P participated in a training program which consisted of 1 training course and 3 evaluation scenarios. The training course included lectures, demonstration, and practice and focused on how to perform endotracheal intubation in soiled airway with the S.A.L.A.D technique. The first scenario was performed on standard airway mannequin head with clean airway (control scenario). The second scenario (pre-training scenario) and the third scenario (post-training scenario) were performed in airway with simulated massive vomiting. The post-training scenario was applied immediately after the training course. All trainees were requested to perform endotracheal intubation for 3 times in each scenario. The "pass" of a scenario was defined as more than twice successful intubation in a scenario. The intubation time, count of successful intubation, pass rate, and the confidence in endotracheal intubation were evaluated.The intubation time in the post-training scenario was significantly shorter than that in the pre-training scenario (P = .031). The pass rate of the control, pre-training, and post-training scenario was 100%, 82.9%, and 92.7%, respectively. The proportion of trainees reporting confident or very confident in endotracheal intubation in soiled airway increased from 22.0% to 97.6% after the training program. Kaplan-Meier analysis revealed that the adjusted hazard ratio of successful intubation for post-training versus pre-training scenario was 2.13 (95% confidence interval of 1.57-2.91).The S.A.L.A.D. technique training could efficiently help EMT-P performing endotracheal intubation during massive vomiting simulation.

Background: Carbon monoxide (CO) poisoning may result in acute neurological sequelae, cognitive sequelae, and delay neurological sequelae. The administration of hyperbaric oxygen (HBO) to prevent the development of delayed neurological sequelae in CO poisoning have extensively investigated but conflicting results have been reported. We performed a systematic literature review and meta-analysis of randomized controlled trials (RCTs) evaluating HBO treatment and its effect on neuropsychometric dysfunction after CO poisoning., Methods: We searched Medline, Embase, Pubmed, and the Cochrane Register of Controlled Trials from inception to December 2017. Eligible studies compared HBO therapy with normobaric oxygen (NBO) in patients with CO poisoning., Results: Six studies compared HBO with NBO in CO poisoning patients. Compared with patients treated with NBO, a lower percentage of patients treated with HBO reported headache (16.2% vs 16.5%, relative risk [RR] = 0.83, 95% CI = 0.38-1.80), memory impairment (18.2% vs 23.8%, RR = 0.80, 95% CI = 0.43-1.49), difficulty concentrating (15.0% vs 18.4%, RR = 0.86, 95% CI = 0.55-1.34), and disturbed sleep (14.7% vs 16.2%, RR = 0.91, 95% CI = 0.59-1.39). Two sessions of HBO treatment exhibited no advantage over one session., Conclusions: The meta-analysis indicated that compared with CO poisoning patients treated with NBO, HBO treated patients have a lower incidence of neuropsychological sequelae, including headache, memory impairment, difficulty concentrating, disturbed sleep, and delayed neurological sequelae. Taking into consideration the cost-effectiveness of one session of HBO, one session of HBO treatment could be an economical option for patients with CO poisoning with high severity.
