Giant haemangioma of the tongue is a disease which can obstruct the oropharyngeal airway and is presented with obstructive symptoms. Due to its vascularity, inserting laryngoscope for intubation can cause high risks, such as inducing bleeding. Hypoxia and excessive bleeding must be anticipated while securing the airway. We present a case of novel usage of dexmetomidine as a conscious sedation agent for awake fibre optic intubation in a 9-year-old child with obstructive symptoms secondary to a huge tongue haemangioma, who was presented for interventional sclerotherapy of the lesion.

Background: Normal saline (NS) is a common fluid of choice in neurosurgery and neurointensive care unit (ICU), but it does not contain other electrolytes and has the potential to cause hyperchloremic metabolic acidosis with prolonged infusion. These problems may be reduced with the availability of balanced fluid (BF), which becomes a more physiological isotonic solution with the presence of complete electrolyte content. This study aimed to compare the changes in electrolytes and acid–base between NS and BF (Sterofundin® ISO) therapy for post-operative severe traumatic brain injury (TBI) patients in neuro-ICU. Methods: Sixty-six severe TBI patients who required emergency craniotomy or craniectomy and were planned for post-operative ventilation were randomised into NS (n = 33) and BF therapy groups (n = 33). The calculation of maintenance fluid given was based on the Holliday-Segar method. The electrolytes and acid–base parameters were assessed at an 8 h interval for 24 h. The data were analysed using repeated measures ANOVA. Results: The NS group showed a significant lower base excess (-3.20 versus -1.35, P = 0.049), lower bicarbonate level (22.03 versus 23.48 mmol/L, P = 0.031), and more hyperchloremia (115.12 versus 111.74 mmol/L, P < 0.001) and hypokalemia (3.36 versus 3.70 mmol/L, P < 0.001) than the BF group at 24 h of therapy. The BF group showed a significantly higher level of calcium (1.97 versus 1.79 mmol/L, P = 0.003) and magnesium (0.94 versus 0.80 mmol/L, P < 0.001) than the NS group at 24 h of fluid therapy. No significant differences were found in pH, pCO2, lactate, and sodium level. Conclusion: BF therapy showed better effects in maintaining higher electrolyte parameters and reducing the trend toward hyperchloremic metabolic acidosis than the NS therapy during prolonged fluid therapy for postoperative TBI patients.

Background: Existing techniques of predicting difficult laryngoscopy are inadequate requiring evaluation of Maxillopharyngeal Angle (MP-A) on lateral cervical radiograph described. Objectives: This study aimed to compare MP-A test with Modified Mallapati Test (MMT) in predicting their diagnostic values and Area Under Curve of Receiver Operating Characteristic Curve (AUCROCC) of both test. Methods: This is a double blinded interventional study of 93 patients. Each patient’s MMT score was assessed during preoperative assessment and subsequent MP-A test done by obtaining lateral cervical radiograph with the head in neutral position. Laryngeal view was assessed using Cormack-Lehane grade after induction of anesthesia, was used as reference standard to determine the diagnostic values of MMT and MP-A respectively. Results: The MP-Acompared to MMT in predicting difficult larngoscopy had higher sensitivity (77.78 vs 44.44) specificity (88.10 vs 67.86) and accuracy (87.10 vs 65.59) with higher Odd Ratio(26.12 vs 1.68). The AUCROCC was significantly higher in MP-A test 0.83(95%CI: 0.67, 0.99) (P = 0.001) vs MMT 0.56(95%CI: 0.36, 0.76) (P = 0.546) with LR+ of 6.53 vs 1.38. Conclusion: The Maxillopharyngeal Angle test was superior in predicting difficult laryngoscopy as compared to Modified Mallampati Test.difficult intubation
