Abstract
BACKGROUND: Serratus anterior plane block (SAPB) has been proven to be an efficient way to control postoperative pain. This study explored whether the use of continuous SAPB in combination with flurbiprofen could improve early pulmonary function in lung cancer patients undergoing video-assisted thoracoscopic surgery (VATS). METHODS: From July 2019 to April 2020, patients who scheduled for elective lung resection undergoing VATS were randomly allocated to receive patient-controlled SAPB in combination with intravenous flurbiprofen or patient-controlled intravenous analgesia. Postoperative pulmonary function variables, including forced expiratory volume in 1 second, and forced vital capacity were collected before and 24, 48, and 72 hours after Surgical Procedure. Pain intensity was measured at rest and on coughing. Comfort scores during breathing exercises, postoperative pulmonary complications, and adverse events were recorded. RESULTS: A substantial reduction in lung function was exhibited in both groups after Surgical Procedure (P < .001), but lung function variables in the continuous SAPB group were significantly higher (P < .001) throughout the postoperative period up to 72 hours, regardless of the surgical procedure type. Meanwhile, there were significant differences of pain intensity at rest and on coughing between the groups (P < .001). The incidence of pneumonia, pulmonary atelectasis, hypoxemia, vomiting, and the comfort score in the continuous SAPB group was significantly lower (P < .05). CONCLUSIONS: Postoperative acute pain treatment with continuous SAPB in combination with flurbiprofen enhanced pulmonary function and reduced postoperative pulmonary complications in lung cancer patients undergoing VATS.
