UNASSIGNED: Airway ultrasound has been increasingly used in correct positioning of endotracheal tube. We hypothesize that a safe distance between endotracheal tube tip and carina can be achieved with the aid of ultrasound.
UNASSIGNED: Our primary objective was to determine whether ultrasound guided visualisation of proximal end of endotracheal tube cuff is better when compared to conventional method in optimal positioning of tube tip. The secondary objective was to find the optimal endotracheal tube position at the level of incisors in adult Indian population.
UNASSIGNED: There were 25 patients each in the conventional group and the ultrasound group. Conventional method includes auscultation and end tidal capnography. In the ultrasound group the upper end of the endotracheal tube cuff was positioned with an intent to provide 4 cm distance from the tube tip to the carina. X ray was used in both groups for confirmation of tip position and comparison between the two groups. Further repositioning of the tube was done if indicated and the mean length of the tube at incisors was then measured.
UNASSIGNED: After x ray confirmation, endotracheal tube repositioning was required in 24% of patients in the USG group and 40 % of patients in the conventional group. However, this result was not found to be statistically significant (p = 0.364). The endotracheal tube length at the level of teeth was 19.4 ± 1.35 cm among females and 20.95 ± 1.37 cm among males.
UNASSIGNED: Ultrasonography is a reliable method to determine ETT position in the trachea. There was no statistically significant difference when compared to the conventional method. The average length of ETT at the level of incisors was 19.5 cm for females and 21 cm for males.

BACKGROUND: The efficacy and safety of cuffed endotracheal tubes (ETTs) in neonates are still unclear, this study aimed to assess the efficacy of cuffed versus uncuffed ETTs in neonate undergoing noncardiac surgeries.
METHODS: Neonates scheduled for noncardiac surgeries were randomized into two groups according to the type of airway device during general anesthesia: cuffed ETT group (n = 60) and the uncuffed ETT group (n = 60). The primary outcome was the incidence of ETT exchange to find the appropriate ETT. Other outcomes included: duration of intubation, lung ultrasound score, and incidence of postoperative complications (croup, wheezes, hypoxia, etc.).
RESULTS: The frequency of ETT exchange was lower in the cuffed ETT group compared to the uncuffed one {1 (1.7%) vs. 28 (46.7%), p = .0001; relative risk [95% confidence interval]: 0.54 [0.43-0.69]}. Postoperative adverse events were comparable between both groups except for significantly higher post extubation croup in the uncuffed ETT group compared to the cuffed ETT {10 (16.7%) vs. 3(5%), p value = .04, relative risk (95% confidence interval): 1.14 (1-1.29)}.
CONCLUSIONS: In full term neonates undergoing noncardiac surgeries, the use of cuffed ETT was associated with less need to tracheal tube exchange and less incidence of postoperative croup, without increasing the postoperative respiratory complications compared to uncuffed ETT.

Coccidioidomycosis is a fungal infection primarily Endemic in the Southwest United States. Disseminated Coccidioidomycosis is a life-threatening variant that mainly occurs in an immunocompromised host. This report describes an unusual presentation of disseminated Coccidioidomycosis in an immunocompetent individual. The patient was admitted with a subacute cough, progressively worsening shortness of breath, significant weight loss, nodular skin lesions in upper extremities, and acute hypoxemic respiratory failure. Chest imaging revealed extensive nodularity and mass-like lesions. What sets this case apart is the significant endotracheal and endobronchial involvement, which mimicked metastatic lung cancer. The diagnosis was confirmed through serology and bronchoscopy biopsy. This case underscores the critical importance of considering detailed travel history and maintaining a high index of suspicion for fungal infections in patients with endobronchial lesions, particularly in regions where Coccidioidomycosis is endemic.

UNASSIGNED: To compare perioperative adverse events between general anesthesia with endotracheal tube (ETT) and general anesthesia with laryngeal mask airway (LMA) in patients undergoing laparoscopic hysterectomy.
UNASSIGNED: This was a large sample retrospective, propensity score-matched (PSM) study. We collected the data of 6739 female patients who underwent laparoscopic hysterectomy between January 2016 and June 2021 in our hospital, China. Patients were divided into two groups (ETT group and LMA group) according to different airway management modes. Data on all perioperative adverse events were collected. PSM analysis was performed to control confounding factors and differences in baseline values between the two groups. Finally, 4150 female patients were recruited after PSM.
UNASSIGNED: The total number of patients taking intraoperative vasoactive drugs during surgery was higher in the ETT group than in the LMA group (P = 0.04). The LMA group had a higher incidence of vomiting (51 [2.46%]) and somnolence (165 [7.95]) in the postanesthesia care unit (PACU) than the ETT group (71 [3.42%] and 102 [4.92%], respectively) (P = 0.02 and P < 0.001). Hypothermia was significantly higher in the LMA group (183 [10.36%]) than in the ETT group (173 [8.34%]) in the PACU (P = 0.03). The number of patients with sore throat was significantly higher in the ETT group (434 [20.02%]) than in the LMA group (299 [14.41%]) in the ward (P < 0.001). Other variables such as hypoxemia, moderate to severe pain, abdominal distension, diarrhea, sleep disorders, wound bleeding, and skin itch were not significantly different between the two groups (P > 0.05).
UNASSIGNED: The ETT group had more incidences of vomiting, sore throat, and cough complications and needed more drug treatment than the LMA group. LMA is a better airway management mode and LMA general anesthesia can be safely used in patients undergoing laparoscopic nonemergency hysterectomy.

Airway compromise is the second leading cause of potentially preventable death on the battlefield. Prehospital airway management is often unavoidable in a kinetic combat environment and expected to increase in future wars where timely evacuation will be unreliable and air superiority not guaranteed. We compared characteristics of survivors to non-survivors among combat casualties undergoing prehospital airway intubation.
We requested all Department of Defense Trauma Registry (DODTR) encounters during 2007-2023 with documentation of any airway intervention or assessment within the first 72-h after injury. We conducted a retrospective cohort study of all casualties with intubation documented in the prehospital setting. We used descriptive and inferential statistical analysis to compare survivors through 7 days post injury versus non-survivors. We constructed 3 multivariable logistic regression models to test for associations between interventions and 7-day survival after adjusting for injury severity score, mechanism of injury, and receipt of sedatives, paralytics, and blood products.
There were 1377 of 48,301 patients with documentation of prehospital intubation in a combat setting. Of these, 1028 (75%) survived through 7 days post injury. Higher proportions of survivors received ketamine, paralytic agents, parenteral opioids, and parenteral benzodiazepines; there was no difference in the proportions of survivors versus non-survivors receiving etomidate. The multivariable models consistently demonstrated positive associations between 7-day survival and receipt of non-depolarizing paralytics and opioid analgesics.
We found an association between non-depolarizing paralytic and opioid receipt with 7-day survival among patients undergoing prehospital intubation. The literature would benefit from future multi-center randomized controlled trials to establish optimal pharmacologic strategies for trauma patients undergoing prehospital intubation.

BACKGROUND: Airway ultrasound has recently promised to be a valuable addition to preoperative airway assessment tools. This study was undertaken to determine the efficacy of ultrasound-guided measurement of soft tissue thickness (STT) at various levels of the anterior neck in predicting difficult airways in an eastern Indian population.
OBJECTIVE:  The primary objective was to find out the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of anterior neck soft tissue thickness at the level of the hyoid (STT-Hyoid) and vocal cords (STT-VC), distance from the skin to the epiglottis midway (DSEM), and the ratio of the depth of the pre-epiglottic space (Pre-E) to the distance from the epiglottis to the mid-point of the vocal cords (E-VC). The secondary objective was to develop a scoring system using these parameters.
METHODS: One hundred eighty-eight patients aged 18-65 years who received general anesthesia and endotracheal intubation for surgery were included in the study. Anterior neck soft tissue thickness measurements were done preoperatively using ultrasound. The actual difficulty of the airway was graded by the anesthesiologist while performing endotracheal intubation using the intubation difficulty scale (IDS).
RESULTS: The incidence of a difficult airway (IDS > 5) was 9.04%. The STT-Hyoid and STT-VC had a moderate correlation with IDS. The DSEM and Pre-E/E-VC ratios had a weak correlation with IDS. For difficult airway prediction, the cutoff points of STT-Hyoid and STT-VC were 7.95 mm and 24.25 mm, respectively. The combined cutoff measurements of STT-Hyoid and STT-VC (29.95 mm) were better predictors of difficult airway.
CONCLUSIONS: Preoperative airway ultrasound examination measuring the soft tissue thickness at the hyoid and vocal cord levels is an effective modality in predicting a difficult airway. However, further studies are needed to validate this finding in populations of varied ethnicity and demographic distribution.

UNASSIGNED: Endotracheal intubation and mechanical ventilation are the most frequently used life-sustaining interventions in critical care. Prolonged intubation can lead to post-extubation dysphagia, affecting the individual\'s nutritional level and communication ability. Thereupon, this study aims to assess the effectiveness of swallowing and oral care interventions in resuming oral intake and increasing salivary flow in post-extubation patients.
UNASSIGNED: A randomized controlled trial was conducted in critical care units of a tertiary care setting, where 92 post-extubation patients who had undergone intubation for≥48 hours were enrolled. The intervention group received swallowing and oral interventions, including safe swallowing education (SSE), toothbrushing, salivary gland massage, oral cavity, and swallowing exercises. In contrast, the control group received standard oral care every 8th hour. Oral intake was assessed daily with the Functional Oral Intake Scale, and the salivary flow measurement was assessed with oral Schirmer\'s test on the 1st, 3rd, and 7th day after extubation.
UNASSIGNED: The baseline demographic and clinical characteristics showed that the groups were homogenous. The intervention group achieved total oral intake two days earlier than the control group. Findings also showed that the participants in the intervention group had a significant increase in salivary flow than in the control group on the 3rd and 7th days of the intervention.
UNASSIGNED: Swallowing and oral care interventions help post-extubation patients resume early oral intake and increase salivary flow after prolonged intubation. Hence, it improves the patient\'s outcome toward a healthy life.

OBJECTIVE: A lightwand is a stylet with a light bulb at its tip that can be used to guide intubation by confirming the illumination through the anterior neck. We aimed to determine the factors affecting the illumination intensity during lightwand endotracheal intubation.
METHODS: We retrospectively collected data from 180 patients who underwent lightwand endotracheal intubation. We recorded illumination intensity on a 5-point scale. The patients were categorized into weak (score <3) and bright (score ≥3) groups based on the illumination intensity scale score.
RESULTS: A total of 176 patients were analyzed, of whom 125 (71.1%) were enrolled in the bright group, and 51 (29.0%) were enrolled in the weak group. Multivariable logistic regression analysis revealed that an increased body mass index (BMI) and mask ventilation grade were associated with light intensity. For mask ventilation, moderate vs. easy (p=0.010) and difficult vs. easy (p=0.008) were associated with the weak group. Receiver operating characteristic curve analysis showed that BMI ≥24.6 kg/m2 was correlated with the weak group.
CONCLUSIONS: BMI ≥24.6 kg/m2 or mask ventilation grade above moderate indicates increased odds of weak illumination intensity in lightwand intubation. Pre-intubation examination of these factors helps increase the chances of successful intubation.

After endotracheal intubation is performed, the location of the endotracheal tube (ETT) is confirmed followed by assessment of ETT depth. Physical examination can be unreliable and chest radiographs can lead to delayed recognition. Ultrasound may facilitate rapid determination of ETT depth at the bedside; however, the ideal technique is unknown.
This was a randomized trial comparing the static versus dynamic technique for ETT depth assessment using a cadaver model. The ETT was randomized to correct versus deep placement. Seven physicians blinded to ETT location assessed the location using static (direct visualization of an inflated cuff) versus dynamic (active inflation of the ETT cuff) visualization. Outcomes included diagnostic accuracy, time to identification, and operator confidence with subgroup analyses by physician ultrasound experience.
420 total assessments were performed. The static technique was 99.1% (95% CI 94.8%-100%) sensitive and 97.1% (95% CI 91.9%-99.4%) specific. The dynamic technique was 100% (95% CI 96.7%-100%) sensitive and 100% (95% CI 96.7%-100%) specific. Time to identification was faster for the static technique (6.6 s; 95% CI 5.9-7.4 s) versus the dynamic technique (8.7 s; 95% CI 8.0-9.5 s). Operator confidence was lower for the static technique (4.4/5.0; 95% CI 4.3-4.5) versus the dynamic technique (4.7/5.0; 95% CI 4.6-4.8). There were no differences in the findings when assessed among expert or non-expert sonographers.
There was no statistically significant difference in the accuracy of ETT depth identification between the static or dynamic technique. However, utilizing the dynamic technique showed a statistically significant improvement in sonographer confidence and a concomitant increase in time to identification.

Uvular necrosis is a rare post-procedural complication thought to be caused by mechanical compression of the uvula during endotracheal intubation. We described the day-to-day progression of uvular necrosis after right shoulder acromioclavicular (AC) joint reconstruction. We present a case of a 22-year-old male who visited the emergency department after sustaining a right shoulder trauma. Diagnosis of a type V AC dislocation with total coracoclavicular ligament tear was established. On day one, after endotracheal intubation for the right shoulder AC joint reconstruction, the patient complained of severe throat pain that progressed to odynophagia, dysphagia, and choking. Examination revealed an erythematous uvula with well-demarcated necrotic tissue. He was managed conservatively with acetaminophen and ice chips. Day-to-day symptom progression description may guide physicians in managing postoperative uvular necrosis.
