The effects of ultrasound-guided serratus plane block, in combination with general anesthesia, on intraoperative opioid consumption, emergence time, and hemodynamic stability during video-assisted thoracoscopic lobectomy: A randomized prospective study.
Ontology highlight
ABSTRACT: BACKGROUND:Thoracotomy is one of the most painful surgeries; therefore, video-assisted thoracoscopic surgery (VATS) was developed to reduce the surgical stress of thoracotomy. Although VATS results in reduced postoperative pain compared with thoracotomy, it is still painful. Serratus plane block (SPB) is a novel technique that provides lateral chest wall analgesia by blocking the lateral branch of the intercostal nerve. METHODS:We conducted a prospective study in 50 patients, aged 20 to 75 years, undergoing three-port VATS lobectomy. Group G (n?=?25) received conventional general anesthesia and Group S (n?=?25) received SPB before induction of general anesthesia. In Group S, 20 ml of 0.375% ropivacaine was injected between the serratus anterior and latissimus dorsi muscles. During surgery, anesthesia was maintained by adjusting the propofol dose to maintain a bispectral index of 40 to 60 and the remifentanil dose to maintain blood pressure and heart rate within 70 to 130% of baseline. RESULTS:Intraoperative remifentanil consumption was significantly lower in Group S compared to that in Group G (519.9??g vs 1047.7??g, P?
