Anesthetic management of a large mandibular odontogenic myxoma in a child - a case report.

Numerous neoplastic lesions can arise in the orofacial region in the pediatric populations. Odontogenic tumors typically affect the mandible more than the maxilla. Airway management can be challenging in pediatric oral tumors because of the distorted anatomy and physiological variations. Conventional awake fiberoptic intubation is not always possible owing to limited cooperation from the pediatric populations. Herein, we report the case of a 1-year-old child with odontogenic myxoma of the mandible and an anticipated difficult airway. Given the expected difficulties in the airway, video laryngoscope-assisted orotracheal intubation under general anesthesia with maintenance of spontaneous breathing was scheduled. Proper planning and thorough examinations are vital for successful airway management in pediatric patients.

Prediction of the difficult airway by pre-operative ultrasound-based measurement of airway parameters: A prospective observational study.

Background and Aims: Ultrasonography has emerged as a new airway assessment tool. However, its role in predicting difficult airways needs to be explored. This study aimed to evaluate the accuracy of pre-operative ultrasound assessment of the neck in predicting difficult airways in patients undergoing elective surgery under general anaesthesia. Methods: One hundred and fourteen adult patients undergoing elective surgeries under general anaesthesia were enrolled in this study. In the pre-operative room, upper airway ultrasound measurements of the neck were obtained, namely, distance from skin to the hyoid bone, distance from skin to the thyroid isthmus and thickness of the base of the tongue. Clinical airway assessment details were noted from the pre-anaesthetic evaluation form. The airway management technique was noted. Receiver operating characteristic curves were used to assess the diagnostic value of these upper airway ultrasound measurements in predicting difficult airways. Results: The distance from the skin to the thyroid isthmus in the difficult airway group (0.37 ± 0.133 cm) was significantly higher than in the non-difficult group (P = 0.007). It appeared to be a better predictor of difficult airways and correlated better with clinical tests among the measured ultrasound parameters. The body mass index was significantly higher in the difficult airway group (P = 0.009). Conclusion: Considering the difference in means between the two groups, distance from the skin to the thyroid isthmus should be explored as a potential predictor of a difficult airway in studies with a larger sample size.

Prognosis of Spontaneous Pneumothorax/Pneumomediastinum in Coronavirus Disease 2019: The CoBiF Score.

Objectives: Pneumothorax and pneumomediastinum are associated with high mortality in invasively ventilated coronavirus disease 2019 (COVID-19) patients; however, the mortality rates among non-intubated patients remain unknown. We aimed to analyze the clinical features of COVID-19-associated pneumothorax/pneumomediastinum in non-intubated patients and identify risk factors for mortality. Methods: We searched PubMed Scopus and Embase from January 2020 to December 2021. We performed a pooled analysis of 151 patients with no invasive mechanical ventilation history from 17 case series and 87 case reports. Subsequently, we developed a novel scoring system to predict in-hospital mortality; the system was further validated in multinational cohorts from ten countries (n = 133). Results: Clinical scenarios included pneumothorax/pneumomediastinum at presentation (n = 68), pneumothorax/pneumomediastinum onset during hospitalization (n = 65), and pneumothorax/pneumomediastinum development after recent COVID-19 treatment (n = 18). Significant differences were not observed in clinical outcomes between patients with pneumomediastinum and pneumothorax (±pneumomediastinum). The overall mortality rate of pneumothorax/pneumomediastinum was 23.2%. Risk factor analysis revealed that comorbidities bilateral pneumothorax and fever at pneumothorax/pneumomediastinum presentation were predictors for mortality. In the new scoring system, i.e., the CoBiF system, the area under the curve which was used to assess the predictability of mortality was 0.887. External validation results were also promising (area under the curve: 0.709). Conclusions: The presence of comorbidity bilateral pneumothorax and fever on presentation are significantly associated with poor prognosis in COVID-19 patients with spontaneous pneumothorax/pneumomediastinum. The CoBiF score can predict mortality in clinical settings as well as simplify the identification and appropriate management of patients at high risk.

Considerations to Prevent Intraoperative Fluid Spillage Into the Airway From a Bronchogenic Cyst During Anesthesia: A Case Report.

In patients with bronchogenic cysts, spillage of cyst contents into the airway during anesthesia and surgery has been reported. Methods to prevent this complication are not definitive. A 21-year-old man with a large bronchogenic cyst was scheduled for cyst excision during which large quantities of purulent fluid spilled into the airway immediately after induction of anesthesia. This was due to unmasking of the existing communication between the cyst and the bronchial tree. Preoperative percutaneous drainage of the cyst contents, awake intubation, and lung isolation with a bronchial blocker before paralyzing and positioning the patient may be helpful.

ECG Changes Occurring During Chest Liposuction for Gynecomastia - Artifacts or a Cause for Concern?

Currently, liposuction alone or combined with various methods of gland excision has become the standard of care in the surgical management of gynecomastia. Although liposuction is considered a safe and straightforward method of body contouring, serious complications related to the procedure, including deaths, have been reported in the literature. We report the occurrence of ECG artifacts intra-operatively while performing chest liposuction under general anesthesia. Patients may receive unnecessary and potentially dangerous therapeutic interventions if these ECG artifacts are not identified correctly. A careful and rational evaluation of the patient and the ECG by the clinician can accurately identify these pseudo-abnormalities and avoid unnecessary therapies.

Ultrasound guided tracheal intubation with a styleted tracheal tube in anticipated difficult airway.

Ultrasonography is a simple, reliable, non-invasive technique which helps in real-time assessment of airway anatomy and contributes to safer airway management in various settings like operating rooms, intensive care units and emergency departments. It also helps us to plan the appropriate anesthetic technique especially in difficult airway cases. Here, we discuss the importance of styleted tracheal tube in improving the accuracy of ultrasound guided tracheal intubation in anticipated difficult airway.

Comparison of preincisional and postincisional parasternal intercostal block on postoperative pain in cardiac surgery.

BACKGROUND: The optimum cardiac surgical pain management has known to maintain hemodynamic stability and, reduces respiratory and cardiovascular complications. Postoperative parasternal intercostal block has shown to reduce postoperative analgesic consumption after cardiac surgery. Therefore, this study sought to investigate the effectiveness of the preoperative ultrasound guided parasternal block in reducing postoperative pain after cardiac surgery. METHODS: This was a randomized, prospective, interventional, single blind study comprised of 90 adult patients scheduled for cardiac surgery involving sternotomy. Preoperatively and postoperatively, 0.25% bupivacaine administered in 4 mL aliquots into the anterior (2nd-6th) intercostal spaces on each side about 2 cm lateral to the sternal edge with a total volume of 40 mL under ultrasound guidance and direct vision, respectively. Postoperative pain was rated according to visual analogue scale. Secondary outcomes included intraoperative and postoperative fentanyl consumptions, dosages of rescue medications, and time to extubation. MAIN RESULTS: There was no significant differences in visual analogue score visual analogue score at all time points till 24 hours postoperatively. Intraoperative fentanyl requirements (microgram/kg) before cardiopulmonary bypass was significantly lower in pre-incisional group than the post-incisional group (0.16 ± 0.43 vs 0.68 ± 0.72; P = .0001). Furthermore, there were no significant difference in total fentanyl requirement (7.20 ± 2.66 vs 8.37 ± 3.13; P = .06) and tramadol requirement (0.02 ± 0.15 vs 0.07 ± 0.26; P = .28) within first 24 hours. However, time to extubation was significantly higher in the preoperative group (P = .02). CONCLUSIONS: Preoperative and postoperative parasternal intercostal block provide comparable pain relief during the postoperative period.
