Abstract:
Objective:To explore the effects of 30° and 45° angles on the time and comfort of mechanical ventilation and extubation for patients undergoing abdominal surgery.Methods:A total of 64 patients who underwent oral tracheal intubation at SICU in the General Surgery Center of the Critical Care Medical Center of our hospital from January 2018 to November 2018 were selected. A total of 64 patients were randomly divided into group A and group B by random number table method, of which there were 31 people in group A and 33 people in group B. During the experiment, 1 people in group A and 3 people in group B experienced dyspnea during the withdrawal process and terminated treatment. Finally, 30 patients in group A and 30 patients in group B were selected. The bedside angle during group A treatment was 30°, and the bedside angle during group B treatment was 45°. The bedside angle card was used by both groups to measure the height of the bedside during the weaning. The two groups of patients were compared during the weaning period (improved Visual Analogue Scale score), weaning to extubation time, aspiration rate, intubation time, pressure ulcer rate, pulmonary function and hemodynamic changes after extubation.Results:Patients with ventilator to extubation time, during the machine during oxygenation index, pulled machine comfort score in group A were 117.50 (45.25, 189.00) min, (348.20±59.72) mmHg(1 mmHg=0.133 kPa), 1.00 (1.00, 2.00) points, group B were respectively 30.00 (13.50, 42.75) min, (314.60±67.13) mmHg and 3.00 (2.00, 3.00) points, two groups comparing the difference was statistically significant ( Z values was -2.411, -4.806, t value was 2.048, P<0.05 or 0.01). Conclusion:Lifting the bedside 30° during mechanical ventilation withdrawal in patients with abdominal surgery can shorten the time from patient withdrawal to extubation, improve the patient's oxygenation index, and improve the comfort during patient withdrawal. It can be used as an early patient for abdominal surgery. One of the auxiliary intervention measures for withdrawal.
