Video-assisted thoracoscopic surgery (VATS) is less invasive compared to traditional thoracotomy. It is reported that the incidence of acute pain following VATS exceeds 80%. Inadequate postoperative analgesia may trigger a series of adverse physiological stress responses, increase the occurrence of postoperative complications, and affect the rehabilitation process.If acute pain is not managed promptly and sufficiently, nearly one-quarter of patients may develop chronic pain, impacting normal life and sleep quality after discharge. Local infiltration anesthesia at the incision site is one of the simplest, safest, and most effective methods for preventing postoperative incision pain. Liposomal bupivacaine(LB) is a novel, long-acting, sustained-release amide-type local anesthetic, providing localized analgesic effects for up to 72 hours. Some researchers have reported the analgesic effects of LB VS traditional local anesthetics infiltration, but the current research results are highly heterogeneous. More prospective studies are needed to evaluate whether LB infiltration is superior to the traditional local anesthetics for the management of postoperative pain. The investigators designed this study to compare the analgesic effect of using LB plus bupivacaine for local infiltration with bupivacaine along for patients after VATS.

This study is designed as a prospective observational cohort to evaluate recovery after video-assisted thoracoscopic surgery (VATS). In our clinic, anesthesia for VATS is commonly provided either with target-controlled infusion (TCI) or with inhalational agents, depending on the routine practice of the anesthesiologist. No randomization or additional intervention will be performed. During the study period, patients who receive either method as part of standard care will be followed, and perioperative and postoperative data will be recorded. Awakening time, extubation time, Aldrete score progression, pain levels, and early postoperative complications will be compared between the two groups. The aim is to better understand how these widely used anesthesia techniques may influence recovery in VATS patients and to support future clinical decision-making.

Video-assisted thoracoscopic surgery (VATS) is a minimally invasive procedure performed through small thoracic incisions, but postoperative pain remains significant due to tissue and rib trauma. Poorly controlled pain may lead to chronic postoperative pain; therefore, optimal analgesia is essential. According to PROSPECT guidelines, erector spinae plane block (ESPB) or paravertebral block (PVB) are recommended for VATS. The recently defined serratus posterior superior intercostal plane block (SPSIPB) provides analgesia between C3-T10 levels, but its efficacy compared with ESPB has not been studied. This study aims to compare postoperative analgesic efficacy and patient satisfaction between ESPB and SPSIPB in VATS patients.

Lung isolation is primordial in thoracic surgery. To achieve it, two techniques are used: the double lumen tube (DLT) and the bronchial blocker (BB). Left-sided DLT (L-DLT) is use by the majority of anesthesiologists for both left and right thoracic surgeries. Standard right-sided DLT (Rs-DLT) is rarely use since it is dif¬ficult to properly position it and that there is a risk of misalignment between the lateral orifice of the tube and the origin of the right upper lobe (RUL) bron¬chus. In 2007, the investigators have published results suggesting enlarging the Rs-DLT's lateral orifice. The modified R-DLT (Rm-DLT) was more frequently in an adequate position: 77% vs 37% of patients (p = 0.0121), and easier to reposition: 97% vs 74% of patients (p= 0.0109) in comparison to the standard R-DLT group. The data suggest the superiority of the Rm-DLT compared to Rs-DLT for optimal positioning to facilitate one-lung ventilation (OLV) during thoracic surgery. It is believed that DLT tend to provide quicker and better quality of lung collapse than BB. In 2013, investigators have demonstrated an equivalent quality of lung collapse (LC) between L-DLT and BB used with two apnea periods when initiating OLV. Complementary analysis showed a significative difference to obtain complete LC (CLC) between L-DLT for left thoracoscopy and L-DLT for right thoracoscopy and BB in right or left surgery. The investigator hypothesis is that, when using L-DLT for left video-assisted thoracoscopic surgery (VATS), LC of the isolated lung will be slower and of poorer quality compare to the use of the Rm-DLT. The primary objective is to compare the delay between pleural opening (PO) and CLC in left VATS when using three lung isolation devices: 1) L-DLT and 2) Rm-DLT. Secondary objectives are: 1) to evaluate quality of LC, 2) to evaluate the level of obstruction of the lumen of the left bronchus, 3) to evaluate the quality of OLV (PaO2) 4) To collect blind surgeon's opinion about de device used and 5) to measure the delay between OLV and PO for evaluating the role of absorption atelectasis in obtaining CLC. After obtaining IRB approval, the investigators propose a study of 40 patients undergoing an elective left VATS at IUCPQ involving one lung ventilation. They will have to be 21 years or more, to read, understand and sign an informed consent at their pre-operative evaluation. This study will be prospective, randomized, and blind to thoracic surgeons.
