Comparison of incidence of sore throat with laryngeal mask airway Protector and laryngeal mask airway ProSeal: A randomised clinical trial. Indian J Anaesth 2024; 68:637-643. [PMID: 39081918 PMCID: PMC11285887 DOI: 10.4103/ija.ija_1068_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 05/04/2024] [Accepted: 05/06/2024] [Indexed: 08/02/2024] Open
Abstract
Background and Aims Postoperative sore throat (POST) can be as high as 42% in supraglottic devices. LMA® Protector™ is a novel second-generation laryngeal mask airway (LMA) with Cuff Pilot™ technology that allows continuous cuff pressure monitoring. Elevated cuff pressure is a risk factor for POST in supraglottic devices, so we conducted this study to determine whether continuous cuff pressure monitoring can alleviate POST. Methods This randomised double-blinded clinical trial compared the incidence of sore throat between LMA® Protector™ and LMA® ProSeal™ and was conducted in 118 patients scheduled for elective short surgical procedures. They were randomised to either LMA® Protector™ (Group PT) or LMA® ProSeal™ (Group P). The airway was secured with either of the two devices. The primary outcome was the incidence of sore throat at 1, 6, and 24 hours postoperatively and compared using the Chi-square test along with other parameters like first attempt success rate and blood staining of the device. The time taken for insertion and oropharyngeal seal pressure were compared using an independent t-test. Results The incidence of POST was low with Group PT (12%) compared to Group P (28.8%) (P = 0.005). The mean oropharyngeal seal pressure was significantly higher in Group PT than in Group P [33.72 (3.07) versus 27.72 (3.88) cm of H2O], P < 0.005. The first attempt success rate was 81.2% and 100% in LMA® Protector™ versus LMA® ProSeal™. Conclusion LMA® Protector™ had a reduced incidence of POST compared to LMA ProSeal. However, a longer insertion time and difficult placement may be a concern.

Abstract
BACKGROUND Postoperative sore throat (POST) is a common complication following endotracheal tube removal, and effective preventive strategies remain elusive. This trial aimed to determine whether actively regulating intraoperative cuff pressure below the tracheal capillary perfusion pressure threshold could effectively reduce POST incidence in patients undergoing gynecological laparoscopic procedures. METHODS This single-center, randomized controlled superiority trial allocated 60 patients scheduled for elective gynecological laparoscopic procedures into two groups: one designated for cuff pressure measurement and adjustment (CPMA) group, and a control group where only cuff pressure measurement was conducted without any subsequent adjustments. The primary outcome was POST incidence at rest within 24 h post-extubation. Secondary outcomes included cough, hoarseness, postoperative nausea and vomiting (PONV) incidence, and post-extubation pain severity. RESULTS The incidence of sore throat at rest within 24 h after extubation in the CPMA group was lower than in the control group, meeting the criteria for statistically significant superiority based on a one-sided test (3.3% vs. 26.7%, P < 0.025). No statistically significant differences were observed in cough, hoarseness, or pain scores within 24 h post-extubation between the two groups. However, the CPMA group had a higher incidence of PONV compared to the control group. Additionally, the control group reported higher sore throat severity scores within 24 h post-extubation. CONCLUSIONS Continuous monitoring and maintenance of tracheal tube cuff pressure at 18 mmHg were superior to merely monitoring without adjustment, effectively reducing the incidence of POST during quiet within 24 h after tracheal tube removal in gynecological laparoscopic surgery patients.

Abstract
Background: Enhanced recovery after surgery (ERAS) protocol is an effective evidence-based multidisciplinary protocol to optimize the postsurgical recovery process through perioperative interventions. The aim of the present study was to evaluate the effects of ERAS program on operation-related indicators, complications, pain, and quality of life in patients older than 60 years undergoing the transabdominal preperitoneal (TAPP) approach. Methods: This was a retrospective study of prospectively collected data from a single institution. A total of 160 elderly patients who underwent TAPP were divided into two groups: 80 patients in the ERAS group from January 2019 to December 2020, and 80 patients in the non-ERAS group from January 2021 to December 2022 in the non-ERAS group, and the groups were managed with the ERAS protocol and conventional management, respectively. We compared differences in operation-related indicators, complications, pain, and quality of life between the two groups. Results: Operation-related indicators (exhaust time, postoperative eating time, time to first ambulation, hospitalization cost, and postoperative hospital stay) and early postoperative pain of the ERAS group were superior to those of the non-ERAS group, and the difference had statistical significance (P < .05). More importantly, our results demonstrated that compared with the non-ERAS group, the application of ERAS in inguinal hernia patients may reduce postoperative complications (urinary retention, chronic pain) and improve quality of life. Conclusion: The ERAS program might provide the efficiency and safety approach to optimize clinical outcomes in the elderly patients older than 60 years undergoing TAPP approach.

Abstract
Objective Inflation of the endotracheal tube cuff is needed for providing ventilation. Cuff pressure should be maintained inside the appropriate range to prevent critical airway complications. The purpose of this study is to evaluate the pressure changes in the endotracheal tube cuff during otorhinolaryngologic surgery. Design and method This single-center observational study was conducted at Severance Hospital in Korea between April 2020 and November 2020. Patients aged >20 years scheduled to undergo otorhinolaryngological surgical procedures were enrolled. Patients undergoing planned tracheostomy and those who were slated for uncuffed endotracheal tube use were excluded. Intubation was performed after the induction of general anesthesia. A pressure transducer was connected to the pilot balloon of the endotracheal tube, and cuff pressure was continuously monitored until extubation. If the cuff pressure was not appropriate for more than 5 min, it was adjusted to the appropriate range by injecting or removing air. The percentage of time for which the cuff pressure remained within the appropriate range was calculated and defined as the time in the therapeutic range (TTR). The presumed cause for the rise or fall in cuff pressure was identified. Results In total 199 patients, alterations in cuff pressure outside the appropriate range occurred in 191 patients (96.0%). The mean TTR was 79.7% (SD 25.0%), and head and neck surgery had the lowest mean TTR of 69.0% compared to ear and nose surgeries (94.2 and 82.1%, respectively). Sixty-eight patients (34.2%) demonstrated inadequate endotracheal tube cuff pressure for more than 20% of the total anesthesia time. Twenty-six patients (13.1%) demonstrated optimal endotracheal tube cuff pressure for less than 50% of the total anesthesia time. The causative factors inducing inappropriate cuff pressure were found to vary, including positional changes, surgical procedure, anatomical manipulation, and anesthetic procedure. Conclusion In otorhinolaryngologic surgery, cuff pressure increased or decreased outside the appropriate range due to various factors. Therefore, we suggest close continuous monitoring of cuff pressure during anesthesia for otorhinolaryngologic surgery. Clinical trial registration clinicaltrials.gov, identifier NCT03938493.

Abstract
Background : After endotracheal intubation, the endotracheal cuff gets inflated to a sufficiently high pressure to prevent air leaking. Placing a patient in Trendelenburg position and establishing a pneumoperitoneum affects the endotracheal cuff pressure.
Objectives : Determine the impact of these factors on the endotracheal cuff pressure.
Design and setting : This prospective, observational study was conducted in the Catharina Hospital (Eindhoven, the Netherlands).
Methods : This study included adult patients undergoing laparoscopic surgery. A routine endotracheal tube was inserted, in which the cuff pressure was continuously monitored.
Main outcome measures : The outcome of interest was a change in endotracheal cuff pressure after establishment of a pneumoperitoneum and/ or placing a patient in a Trendelenburg position.
Results : 39 patients were included. Cuff pressures in- creased significantly from the moment of pneumo-peritoneum, placing a patient into a Trendelenburg position increased endotracheal cuff pressure and peak pressures even more. The highest endotracheal cuff pressure was 67 cm H2O, the highest registered peak pressure was 35 cm H2O.
Conclusion : Both endotracheal cuff pressure and peak pressure increased during laparoscopic surgical procedures with a pneumoperitoneum and the patient placed in Trendelenburg position. Measuring the endo-tracheal cuff pressure only after endotracheal intubation is insufficient and should be repeated during surgery on fixed moments.

Comparison of effects of volume-controlled and pressure-controlled mode of ventilation on endotracheal cuff pressure and respiratory mechanics in laparoscopic cholecystectomies: A randomised controlled trial. Indian J Anaesth 2020; 64:842-848. [PMID: 33437071 PMCID: PMC7791417 DOI: 10.4103/ija.ija_949_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Revised: 05/25/2020] [Accepted: 08/26/2020] [Indexed: 11/17/2022] Open
Abstract
Background and Aims: One of the pathophysiological consequences of pneumoperitoneum is variations in endotracheal cuff pressure (ETTc). Volume-controlled mode and pressure-controlled mode of ventilation being two modes of ventilatory strategies; we intended to find out variations in ETTc governed by respiratory mechanics between these two modes during laparoscopic cholecystectomies. Methods: After obtaining ethics committee approval, this randomised (1:1), active-controlled, parallel-assigned study was done on 60 patients undergoing laparoscopic cholecystectomies. These patients were allocated into two groups by computer-generated randomisation: Volume-controlled mode (V) and pressure-controlled mode (P). We observed for variations in ETTc which was the primary aim and haemodynamic parameters; respiratory mechanics at baseline (T1), at pneumoperitoneum (T2), after 10 min (T3), 20 min (T4) of pneumoperitoneum and at desufflation (T5). Post-operative laryngotracheal co-morbidities were also observed. Analysis was done using Statistical Package for the Social Sciences version 16.0 (IBM SPSS Statistics, Somers NY, USA). Results: No statistically significant difference was found in both groups either concerning ETTc, haemodynamic parameters or complications. In both groups, ETTc variation was statistically significant when compared from baseline to desufflation (T1 versus T5) and in group V additionally from baseline to time of pneumoperitoneum (T1 versus T2). Group P showed lower peak airway pressure at desufflation and higher mean airway pressure throughout at all the time intervals. Conclusions: There is no variation in ETTc between the two modes. Group P appears to be better in terms of lower Ppeak and better Pmean.
