Supraglottic jet oxygenation and ventilation – A novel ventilation technique
Sushan Gupta

Indian Journal of Anaesthesia 2020 64(1):11-17

Supraglottic jet oxygenation and ventilation (SJOV) is a novel minimally invasive supraglottic technique of jet ventilation which has shown superior results in maintaining oxygenation without any major complications. Theoretically, it could maintain PaO2and PaCO2 within physiological limits for as long as required, the maximum duration reported till now is 45 min. The distinct advantage of SJOV over techniques of nasal oxygenation is its ability to record EtCO2during the periods of ventilation. In addition, it also provides reliable airway access by the blind passage of the endotracheal tube into the trachea with a high success rate even in Cormack-Lehane-III (CLIII) grading patients. Potential complications seen with SJOV include nasal bleed and sore throat. No studies have shown to cause severe barotrauma. In this article, we review the evidence regarding oxygenation, ventilation, indications, airway patency and complications of SJOV in comparison to other more commonly used supraglottic oxygenation and ventilation devices.

Background and Aims: The relationship between intra-operative hypotension and post-operative complications has been recently studied in non-cardiac surgery. Little is known about this relationship in traumatic hip surgery. Our study aimed to investigate this relationship. Methods: A retrospective study was conducted on patients who underwent surgical correction of traumatic hip fracture between 2010 and 2015. We reviewed the perioperative blood pressure readings and the episodes of intra-operative hypotension. Hypotension was defined as ≥30% decrease in the pre-induction systolic blood pressure sustained for ≥10 min. The relationship between intra-operative hypotension and post-operative complications was evaluated. Post-operative complications were defined as new events or diseases that required post-operative treatment for 48 h. Factors studied included type of anaesthesia, blood transfusion rate, pre-operative comorbidities and delay in surgery. We used the Statistical Package for Social Sciences (SPSS, IBM 25) to perform descriptive and non-parametric statistics. Results: A total of 502 patients underwent various types of traumatic hip surgery during the study period. Intra-operative hypotension developed in 91 patients (18.1%) and 42 patients (8.4%) developed post-operative complications. Significantly more patients with hypotension developed post-operative complications compared to patients with stable vitals (18.7% vs. 6.1; P < 0.001). There was no statistically significant difference in the incidence of post-operative complication in patients receiving general or spinal anaesthesia. Pre-operative comorbidities had no significant relationship with post-operative complications. Intra-operative blood transfusion was related to both intra-operative hypotension and post-operative complications. Conclusion: There was an association between intra-operative hypotension and post-operative complications in patients undergoing traumatic hip surgery.

Background and Aims: Intense bleeding during general anaesthesia (GA) is the major limitation during functional endoscopic sinus surgery (FESS). This study was aimed to compare the efficacy of dexmedetomidine and magnesium sulphate (MgSO4)for controlled hypotension in FESS. Methods: Sixty eight patients undergoing FESS were randomised to receive either dexmedetomidine 1 μg/kg over 10 min followed by infusion at 0.2 to 0.7 μg/kg/h (Group D) or MgSO440 mg/kg over 10 min followed by an infusion at 10 to 15 mg/kg/h (Group M). Anaesthesia and infusion rates for study drugs were maintained with sevoflurane to keep MAP between 60–70 mmHg throughout the surgery. The time to reach the target MAP, the number of patients requiring a minimum and maximum infusion doses of study drugs were noted. Results: The mean time to achieve target mean arterial pressure (MAP) was less in group D (10.59 ± 2.04) as compared with (21.32 ± 4.65 min) group M (P < 0.001). The target MAP was achieved between 5–15 min in 73.52% patients (Group D) with an infusion dose of 0.2–0.4 μg/kg/h of dexmedetomidine without the use of sevoflurane, while 82.35% patients in group M required 4% sevoflurane along with >12–15 mg/kg/hr infusion of MgSO4to achieve target MAP in 10–20 min. Conclusion: Dexmedetomidine is superior to MgSO4in achieving target MAP in lesser time with minimum infusion dose.

Background and Aims: The multimodal analgesia strategies to minimise opioid-related side effects are highly desirable in bariatric surgical procedures. We evaluated the efficacy of ultrasound-guided transversus abdominis plane (USG-TAP) block and intravenous lidocaine for postoperative analgesia in obese patients undergoing laparoscopic bariatric surgery. Methods: We studied 56 patients with body mass index >35 kg/m2. They were randomly allocated to Lidocaine group (Group A) and USG-TAP group (Group B). Group A patients were given intravenous Lidocaine (1.5 mg/kg) bolus followed by (1.5 mg/kg/h) infusion. Group B patients were given ultrasound-guided bilateral TAP block using 20 cc of 0.375% ropivacaine each side. Postoperative numeric rating pain scale score (NRS) hours were compared. Other parameters compared were total fentanyl requirement, sedation score, postoperative nausea vomiting (PONV) score and patient satisfaction score. A P value < 0.05 was considered statistically significant. Results: The patient in the Group A had lower resting NRS score (P < 0.05) postoperatively and less fentanyl consumption (P < 0.001) than in Group B. The difference in the sedation scores (P = 0.161) and PONV (P = 0.293) score was found to be statistically insignificant between Group A and B. The difference between the two groups was statistically significant with respect to patient satisfaction score with majority of patients having an excellent patient satisfaction score in Group A as compared to Group B. Conclusion: Intravenous Lidocaine as part of multimodal analgesic technique in obese patients undergoing laparoscopic bariatric surgery improves pain score and reduces opioid requirement as compared to USG-TAP Block.

Background and Aims: Intermediate cervical plexus block (CPB) is a new procedure whose analgesic efficacy compared to superficial cervical plexus block is yet to be established. We compared the analgesic efficacy of superficial vs intermediate CPB for post-operative analgesia after thyroid surgery. Methods: Forty-five patients with American Society of Anaesthesiologists' physical status 1 or 2 undergoing total thyroidectomy were recruited. Forty-four patients in superficial/subcutaneous CPB group (n = 22) and intermediate CPB (n = 22) received 20 mL 0.25% bupivacaine with adrenaline 100 μg bilaterally in ultrasound-guided superficial and intermediate cervical plexus block before induction of general anaesthesia., respectively. The primary outcome measure was the postoperative visual analogue scale (VAS) scores at 0, 2, 4, 6, 12 and 24. Secondary outcome measures included the total dose of rescue analgesic required, duration of postoperative analgesia and patient's satisfaction score. Statistical analysis was with the Mann-Whitney U test and independent t-test. Results: The post-operative VAS scores were lower in intermediate CPB group compared to superficial CPB group at 2, 4, 6, 12, 18 and 24 h [P < 0.05]. Time to first rescue analgesic demand was prolonged 10.06 ± 3.62 h in intermediate group compared to 7.94 ± 3.62 h in superficial group [P = 0.017] and total analgesic consumption were lower in intermediate group (71.25 ± 16.70 μg) than the superficial group (101.25 ± 50.31 μg) [P = 0.011]. Conclusion: Ultrasound-guided intermediate CPB reduces post-operative pain scores, prolongs duration of analgesia and decreases demands for rescue analgesia compared to superficial CPB.

Background and Aims: Intraperitoneal instillation of local anaesthetics has been shown to minimise post-operative pain after laparoscopic surgery. This study was aimed to evaluate the post-operative effect of intraperitoneal ropivacaine with and without tramadol in patients undergoing laparoscopic cholecystectomy. Methods: Eighty patients undergoing laparoscopic cholecystectomy were randomised into two groups. Group R received 0.5% ropivacaine 18 mL with normal saline (NS) 2 mL and Group RT received 0.5% ropivacaine 18 mL with tramadol (100 mg, 2 mL) at the end of surgery intraperitoneally through the port. The pain score was monitored using a numerical rating scale (NRS) every 30 min till 4 h post-operatively and then at 6 h, 12 h and 24 h. The primary objective of the study was to compare the severity of pain between the groups. The secondary objectives were to compare the total dose of rescue analgesic and the time to first rescue analgesia between the groups Statistical analysis was performed using statistical package for the social sciences. Chi-square test and Mann Whitney U test were used for analysis. Results: The pain score in Group RT was significantly lower than Group R at 2.5 h to 24 h (P = 0.005). Only 42.5% in Group RT demanded rescue analgesia as compared to 75% in Group R (P = 0.003). Total analgesic consumption of fentanyl was also reduced in the tramadol group (785 μg vs 1800 μg). No significant adverse effects were found. Conclusion: Intraperitoneal instillation of ropivacaine with tramadol reduces the post-operative pain and analgesic requirement in laparoscopic cholecystectomy as compared to ropivacaine alone.
