View clinical trials related to Endotracheal Tube Cuff Pressure.
Filter by:Background: The placement of a cuffed endotracheal tube for the administration of general anesthesia is a routine procedure. In the part of the intubation tube located in the trachea, there is a balloon (cuff) to prevent gase leakage, aspiration of secretions and gastric contents into the lungs. Inadequate inflation of cuff may lead to inadequate ventilation, aspiration and associated complications, while excessive inflation may cause complications in ranging from postoperative pharyngeal complaints to tracheal rupture due to increased cuff pressure. This study aimed to determine the effect of different patient positions on the endotracheal cuff pressure in patients undergoing urological procedures. Methods: This is a prospective study conducted on 200 patients undergoing urological procedures in supine, prone, lateral flank and litotomy positions. After intubation (T0), the cuff pressure was checked with a cuff manometer and adjusted at 25 cmH2O as the baseline and continuously monitored. The cuff pressure was checked again before (T1) and after achieving the final position (T2) and then at 5 (T3), 10 (T4), 15 (T5), 30, 45, 60, 90, 120, 150, 180 minutes after the position, at the end of the procedure (T6) and before extubation (T7). At postoperative 2nd and 12th hours, the patients were interviewed for sore throat, hoarseness and cough.
The goal of this observational study is to learn about whether the loss-of-resistance syringe technique is beneficial when adjusting endotracheal cuff pressure in pediatric patients. The main questions it aims to answer are: - Is the loss of resistance syringe technique useful when adjusting endotracheal cuff pressure in pediatric patients? - Is there a difference between the measurements of two different cuff manometers used in the clinic, if so, what is the safety margin between the two manometers? The participants who will be operated under general anesthesia will be anesthetized with the standard anesthesia method, the cuffs of the endotracheal tubes will be inflated with an epidural loss of resistance syringe, the syringe piston will be released, and then the syringe piston will be pushed back with oscillation. Then, cuff pressures will be measured and recorded with a cuff manometer (VBM Cuff Pressure Gauge) and an electronic injector measuring cuff pressure (AG Cufill).
The main purpose of this study was to assess the effect of each of position (neck extension by under-shoulder pillow and Crowe-Davis retractor use) during adenoidectomy and adenotonsillectomy on the intracuff pressure of ETTs in children.
In routine practice, pressure is often attempted to be adjusted by palpation of the cuff pilot balloon of the endotracheal tube. The aim of our study is to investigate the variation of the reliability of the palpation method, which is widely used in cuff pressure measurement in the absence of a manometer, with clinical experience. Our recommendation is to use an accessible manometer if available.
Increased or decreased intracuff pressures (ICPs) of cuffed endotracheal tubes (cETTs) can lead to many morbidities.The ICPs of cETTs can be changed by the the patients' ear and head&neck surgery positions. We performed this study to show the effect of the routine combination of neck positions on ICP whilst ear and head& neck surgeries. A total of 90 patients were enrolled to the study. Groups 1 and 2 included the patients who underwent right and left ear surgeries, respectively. Group 3 included all patients undergoing head and neck surgery.After the general anesthesia induction, the patients were given a neutral position.The first ICP was measured and adjusted to 18,4 mm Hg (25 cmH2O) at neutral position. Left or right neck rotation was applied to Group 1 or 2 in conformity with the ear operation site and ICP value was documented. Gel pillow with the height of 4,5 cm was placed under the shoulders of Group 3 patients to extend the neck and the ICP was noted. Then, right or left neck rotation was applied depending on the operation side and ICP was documented again. Additionally, ICP values were monitorized continuously in all patients during the surgeries, and documented at 15th, 30th, 60th and 90th minutes at related positions and just before extubation at neutral position. If the ICP value fell below 14,7 mmHg (20 cmH2O) or rose above 22 mmHg (30 cmH2O), ICP was adjusted to 18,4 mm Hg (25 cmH2O) again.
