Audit on Practices of Endotracheal Suctioning in Intensive Care Unit Patients among Health Care Workers (HCWs).

Background: Endotracheal suctioning (ETS) is one of the most frequently performed invasive procedures in intensive care units (ICUs). This audit was aimed at studying current practices and knowledge regarding ETS in the Indian critical care setup, with the background aim of raising awareness regarding correct practices as per current recommendations in critically ill patients. Materials and methods: After registering the trial with the clinical trial registry, India, a structured audit questionnaire containing 20 questions pertaining to ETS was distributed through electronic media among resident doctors working in the ICUs across India. Responses received were statistically analyzed. Results: The questionnaire was sent to 530 clinicians, of which only 200 (37.73%) responded. The audit revealed that only 22% respondents set the maximum negative pressure every time before suctioning, on the suction apparatus and only 32% said they would choose a catheter size of less than half the internal diameter of the endotracheal tube (ETT). About 90% of the respondents did not routinely do any form of documentation of the ETS. Almost 72% of the responders opined that closed suction systems reduce the chances of developing ventilator-associated pneumonia (VAP). Only 46% of respondents thought that no solution should be routinely instilled in ETT during ETS. Conclusion: There is lack of awareness regarding frequency and technique of ETS, infection control and monitoring required during ETS. Institutional protocols should be in place to follow correct guidelines for performing ETS. How to cite this article: Singh R, Bhalotra AR, Sharma S.

Effects of intra-operative infusion of lidocaine on postoperative pain and quality of recovery in patients undergoing gynecological laparoscopic surgery: A randomized controlled trial.

Background and Aims: Early recovery is desirable after day care surgery. Intravenous lidocaine has anti-inflammatory, anti-hyperalgesic, and analgesic effects and by reducing postoperative pain, nausea, vomiting, and duration of postoperative ileus and hospital stay, might be a useful adjuvant to improve recovery after gynecological laparoscopic surgery. Material and Methods: Fifty female patients, aged 18-55 years, undergoing gynecological laparoscopic surgery were randomly allocated to two groups. In Group L, patients received intravenous lidocaine 1.5 mg/kg at induction of anesthesia followed by infusion of 2 mg/kg/hour until the completion of surgery and in Group NS, patients received normal saline infusion. The Global QoR-40 score at 24 hours, pain score in PACU and at 24 hours, nausea/vomiting, PADSS score in PACU and analgesic consumption over 24 hours were assessed and data were analyzed using SPSS version 17 software. Results: Demographic data were comparable in both groups. The mean Global QoR-40 score in Group L was 197.30 ± 2.3 versus 178.74 ± 6.02 in Group NS (P < 0.001). The mean time to attain PADSS ≥9 was 50 min shorter in Group L than in Group NS (P < 0.001). Nausea, vomiting, and anti-emetic requirement were also significantly reduced in Group L as compared to Group NS (P = 0.005) as was the mean pain score over 24 h (P < 0.001) and the total analgesic consumption over the first 24 h after surgery (P < 0.005). Conclusion: Intraoperative intravenous lidocaine infusion resulted in an improved overall Quality of Recovery in patients undergoing ambulatory gynecological surgery.

Comparative evaluation of nebulized versus intravenous dexmedetomidine on intubating conditions during awake fiberoptic nasotracheal intubation.

BACKGROUND: There is a search for an ideal agent to facilitate awake fiberoptic intubation (AFOI). Dexmedetomidine is a selective α2 agonist which can be administered through intravenous, intramuscular, buccal, intranasal & inhalational routes. It provides good intubation conditions without oxygen desaturation but may cause hypotension and bradycardia when administered intravenously. Hence, alternative routes of administering dexmedetomidine which may improve its safety profile are worth exploring. METHODS: In this randomised, controlled, double-blind trial, 46 ASA I/II adult participants scheduled for elective ENT surgery were randomly allocated to Group ND (Nebulised Dexmedetomidine) (n = 23) to receive nebulisation with dexmedetomidine 1µg.kg-1 and Group ID (Intravenous Dexmedetomidine) (n = 23) to receive intravenous dexmedetomidine 1µg.kg-1 before AFOI. All the patients received injection midazolam 1 mg i.v. as premedication before anaesthesia was initiated. The primary outcome was the cough score. The secondary outcomes were the RSS, SAYGO boluses, post-intubation score, hemodynamic parameters, recall of the procedure, patient satisfaction score and any side effects. RESULTS: The cough score was significantly lower in nebulized group (2.43 ± 0.992 vs 3.52 ± 1.082) with p = 0.001. RSS(3.30 ± 0.926 vs 4.22 ± 1.126; p = 0.004), number of SAYGO boluses required (2.74 ± 0.864 vs 3.57 ± 1.161; p = 0.009) & the post intubation score (1.48 ± 0.593 vs 2.17 ± 0.778; p = 0.001) were also significantly lower in nebulized group. CONCLUSIONS: Nebulisation with dexmedetomidine results in desirable degree of sedation and better tolerance of the procedure with adequate attenuation of the haemodynamic responses to intubation.

Changes in Lung Function Parameters after Total Intravenous Anaesthesia and Balanced Anaesthesia with Desflurane: A Prospective Randomised Study.

OBJECTIVE: Following anaesthesia, there is a decrease in pulmonary function. Unlike volatile anaesthetics, propofol decreases the upper airway tone, and total intravenous anaesthesia (TIVA) with propofol may decrease coughing on emergence. Coughing may reduce postoperative atelectasis. Thus, TIVA may lead to greater decreases in lung function postoperatively as compared to balanced anaesthesia with desflurane. METHODS: Sixty patients of either sex, aged 18-60 years and American Society of Anaesthesiologists (ASA) status I/II, who were to undergo mastoid surgery, were randomly allocated to Group B and Group T. Anaesthesia was maintained with desflurane, nitrous oxide and oxygen in Group B, and with TIVA in Group T. Pulmonary function tests (PFT) were done preoperatively, and 1, 3 and 24 hours postoperatively. RESULTS: Demographic data and preoperative PFT were comparable in both groups. One hour after surgery, there was a greater decrease in FEV1 and peak expiratory flow rate (PEFR) in Group T (p=0.044 and 0.042, respectively). Three hours postoperatively, the decrease in MEFR and PEFR was again greater in Group T (p=0.005 and 0.008, respectively), while the MEFR recovered to preoperative values in Group B. By 24 hours, the forced vital capacity (FVC), MEFR and PEFR recovered to preoperative values in Group T, while FVC remained reduced in Group B (p=0.006). CONCLUSION: Both anaesthetic techniques cause a postoperative impairment in the lung function, but while TIVA causes a greater reduction in PFT in the early postoperative period, recovery is also earlier. On the other hand, balanced anaesthesia with desflurane was associated with a greater reduction in PFT at 24 hours.
