Impact of acupressure combined with flexible pressure sensor manometry on anesthesia recovery in patients undergoing Bronchoalveolar lavage: a randomized controlled trial
Abstract
Postoperative cough after bronchoalveolar lavage (BAL) is common and can delay recovery. We evaluated whether acupressure at Tiantu (CV22), Chize (LU5), and Taiyuan (LU9), quantified by a flexible pressure sensor, improves anesthesia recovery. This single-center randomized controlled trial enrolled adults undergoing BAL under general anesthesia with a laryngeal mask airway. Patients were randomized 1:1 to receive acupressure (Group A) or routine PACU care without acupressure (Group C). In Group A, each acupoint was pressed sequentially for 3 min (CV22 → LU5 → LU9) with pressure recorded by a flexible sensor. Primary outcomes were cough severity and frequency; secondary outcomes included PACU time, heart rate, and complications such as tachycardia, hypertension, and stress urinary incontinence. A total of 120 patients were analyzed (60 in each group). Peak acupressure pressures were 30.2 N for CV22, 35.1 N for LU5, and 25.3 N for LU9, each peaking at 2.0 s. Compared with controls, patients receiving acupressure had a significantly shorter PACU stay (mean difference − 16.0 min, 95% CI − 18.9 to − 13.2), lower cough frequency (− 1.06 times/min, 95% CI − 1.83 to − 0.30), and reduced heart rate (− 9.5 beats/min, 95% CI − 13.7 to − 5.4). The incidence of moderate cough (10.0% vs. 48.3%, RR 0.21, 95% CI 0.09–0.46), severe cough (35.0% vs. 60.0%, RR 0.58, 95% CI 0.39–0.87), tachycardia (8.3% vs. 26.7%, RR 0.31, 95% CI 0.12–0.80), and stress urinary incontinence (6.7% vs. 23.3%, RR…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 120 participants or records.
