ABSTRACT
A pregnant woman with large intraoral arteriovenous malformation of tongue obliterating the oral cavity presented for elective cesarean delivery shortly after experiencing spontaneous, large-volume, oral bleeding. This case report describes the unconventional method of securing the airway for ensuring perioperative airway protection and the anesthetic management of the case.

BACKGROUND AND AIMS: We devised a guard which can be slid and fixed over the central venous puncture needle at a desired length (measured through ultrasound) preventing the needle from penetrating deeper into the skin beyond this guard. This randomized, single blinded, controlled study was designed to evaluate the success of ultrasound guided internal jugular vein (IJV) cannulation using measured guided needle with guard in terms of success and occurrence of complications. MATERIAL AND METHODS: After ethical approval and written informed consent from the patients ultrasound-guided right-sided IJV cannulation was done with a conventional puncture needle (length of 6.4 cm) in the control group (n = 210) and with a conventional puncture needle with a guard fixed proximal to the bevel at a distance equal to the distance between the skin entry point and the midpoint of IJV measured with the help of USG in the study group (n = 210). The primary outcome studied was the number of attempts for successful cannulation. The secondary outcomes studied were complications and ease of cannulation. RESULTS: 419 patients were randomized into control (n = 209) and study groups (210). Successful IJV cannulation in the first attempt (primary endpoint) in the study group was significantly higher compared to the control group (98.6 vs. 85.7%, P = 0.007). Posterior venous wall puncture was reduced in the study group, that is, 0.5% (1/210) compared to control group, that is, 8.61% (18/209) (P = 0.001). Common carotid artery puncture was 7.18% (15/209) in control group and 0% (0/210) in study group (P = 0.001). Operators rated better ease in study group (P < 0.001). CONCLUSIONS: The use of measured guided needle with guard significantly improved the accuracy, success and ease of USG guided IJV cannulation and decreased complications.
ABSTRACT
Postintubation tracheal stenosis is preventable yet commonly occurring clinical condition. Early in the disease, nonspecific symptoms may predominate but once the stenosis reaches a critical stage life-threatening respiratory compromise may ensue. Bronchoscopic interventions are an invaluable tool in the management both as a primary treatment and as an interim procedure before the surgery. Optical dilatational tracheoscopy is a safe and minimally invasive procedure in the treatment of benign tracheal stenosis. Involvement of multidisciplinary team early in the treatment planning gives the best possible results.
ABSTRACT
BACKGROUND: Several studies have been conducted in search of appropriate drugs to attenuate hemodynamic responses in laparoscopic cholecystectomy, but till date, no such study has been conducted on patients undergoing laparoscopic nephrectomy. AIM: The study was designed to assess the effect of esmolol and diltiazem infusions on hemodynamic changes during routine laparoscopic transperitoneal simple nephrectomy. SETTINGS AND DESIGN: A prospective double-blinded randomized control trial. SUBJECTS AND METHODS: A total of 120 nonhypertensive patients of the American Society of Anesthesiologists physical Status I and II aged 20-60 years about to undergo laparoscopic nephrectomy were enrolled for the study after obtaining Institute Ethical committee approval. The patients were randomly allocated to one of the three groups. Group I (control group) received 10 ml normal saline intravenously (i.v.) before induction of anesthesia, followed by continuous infusion 10-20 ml/h. Group II (esmolol group) received i.v. esmolol 1 mg/kg diluted in 10 ml similarly, followed by continuous infusion of 10-20 ml/h (5-10 µg/kg/min). Group III (diltiazem group) received i.v. diltiazem 0.2 mg/kg diluted in 10 ml before induction of anesthesia, followed by continuous infusion at 10-20 ml/h (0.08-1.25) µg/kg/min. After completion of surgery, all the infusions were stopped. Data recording were done for changes in hemodynamics throughout the surgery. STATISTICAL ANALYSIS: was done using Chi-square test for categorical data and one-way ANOVA for continuous data. Tukey ("honestly significant difference") post hoc test was applied for intra- and inter-group comparison in cases where ANOVA was significant. P < 0.05 is considered statistically significant. RESULTS: All hemodynamic data: Heart rate (HR), systolic, diastolic, and mean arterial pressure were observed to be significantly higher (P < 0.001) from baseline in control group at the time of creation of pneumoperitoneum, till 20 min thereafter. The values were comparable to baseline in both esmolol and diltiazem group. On intergroup comparison, the patients in esmolol group had significantly lower HR and blood pressures than in diltiazem group at the creation of pneumoperitoneum and at extubation (P < 0.05). Mean dose of esmolol and diltiazem used were 7.25 ± 1.33 µg/kg/min and 1.14 ± 0.77 µg/kg/min, respectively. CONCLUSION: Both esmolol and diltiazem infusion provide stable intraoperative hemodynamics and protection against stress response triggered by pneumoperitoneum in patients undergoing laparoscopic transperitoneal nephrectomy.

BACKGROUND AND AIMS: Post-operative nausea and vomiting (PONV) is highly distressing and unpleasant symptom. Dexamethasone and palonosetron are effective antiemetics with minimal side effect profile. This study compares the efficacy of palonosetron or dexamethasone alone and their combination (palonosetron plus dexamethasone) for prevention of PONV after laparoscopic cholecystectomy. METHODS: This prospective, randomised, double-blind trial was done on 187 adults, American Society of Anesthesiologists Grade I and II patients, aged 18-75 years undergoing laparoscopic cholecystectomy. They were allocated to three groups which were to receive either of the three treatment regimens: dexamethasone 8 mg (Group D, n = 57), palonosetron 0.075 mg (Group P, n = 66) or dexamethasone 8 mg plus palonosetron 0.075 mg (Group PD, n = 64). The primary outcome was incidence of PONV in 24 h and the secondary outcome was a number of rescue antiemetic required. One-way ANOVA test was used to compare the means amongst three groups. To compare the proportions in the groups, Chi-square test/Fisher's exact test/Two proportions Z-test was applied as appropriate. RESULTS: Overall incidences of PONV in the study 24 h postoperatively were 23.4% in PD, 27.2% in P group and 56.14% in D group (P < 0.001). Requirement of rescue antiemetic was more in dexamethasone group than other two groups (PD = 1 time, P = 1.38 times and D = 1.5 times). CONCLUSION: Palonosetron alone and palonosetron-dexamethasone combination were equally effective in the prevention of PONV. Dexamethasone alone was least effective amongst the three groups. There is no difference between palonosetron and palonosetron-dexamethasone for PONV prevention.
