Importance: In minimally invasive thoracic surgery, paravertebral block (PVB) using ultrasound (US)-guided technique is an efficient postoperative analgesia. However, it is an operator-dependent process depending on experience and local resources. Because pain-control failure is highly detrimental, surgeons may consider other locoregional analgesic options. Objective: To demonstrate the noninferiority of PVB performed by surgeons under video-assisted thoracoscopic surgery (VATS), hereafter referred to as PVB-VATS, as the experimental group compared with PVB performed by anesthesiologists using US-guided technique (PVB-US) as the control group. Design, Setting, and Participants: In this single-center, noninferiority, patient-blinded, randomized clinical trial conducted from September 8, 2020, to December 8, 2021, patients older than 18 years who were undergoing a scheduled minimally invasive thoracic surgery with lung resection including video-assisted or robotic approaches were included. Exclusion criteria included scheduled open surgery, any antalgic World Health Organization level greater than 2 before surgery, or a medical history of homolateral thoracic surgery. Patients were randomly assigned (1:1) to an intervention group after general anesthesia. They received single-injection PVB before the first incision was made in the control group (PVB-US) or after 1 incision was made under thoracoscopic vision in the experimental group (PVB-VATS). Interventions: PVB-VATS or PVB-US. Main Outcomes and Measures: The primary end point was mean 48-hour post-PVB opioid consumption considering a noninferiority range of less than 7.5 mg of opioid consumption between groups. Secondary outcomes included time of anesthesia, surgery, and operating room occupancy; 48-hour pain visual analog scale score at rest and while coughing; and 30-day postoperative complications. Results: A total of 196 patients were randomly assigned to intervention groups: 98 in the PVB-VATS group (mean [SD] age, 64.6 [9.5] years; 53 female [54.1%]) and 98 in the PVB-US group (mean [SD] age, 65.8 [11.5] years; 62 male [63.3%]). The mean (SD) of 48-hour opioid consumption in the PVB-VATS group (33.9 [19.8] mg; 95% CI, 30.0-37.9 mg) was noninferior to that measured in the PVB-US group (28.5 [18.2] mg; 95% CI, 24.8-32.2 mg; difference: -5.4 mg; 95% CI, -∞ to -0.93; noninferiority Welsh test, P ≤ .001). Pain score at rest and while coughing after surgery, overall time, and postoperative complications did not differ between groups. Conclusions and Relevance: PVB placed by a surgeon during thoracoscopy was noninferior to PVB placed by an anesthesiologist using ultrasonography before incision in terms of opioid consumption during the first 48 hours.

PURPOSE: Our study aimed to explore the association between early hyperoxemia of the first 24 h on outcomes in patients with severe blunt chest trauma. MATERIALS AND METHODS: In a level I trauma center, we conducted a retrospective study of 426 consecutive patients. Hyperoxemic groups were classified in severe (average PaO2 ≥ 200 mmHg), moderate (≥150 and < 200 mmHg) or mild (≥ 100 and < 200 mmHg) and compared to control group (≥60 and < 100 mmHg) using a propensity score based analysis. The first endpoint was the incidence of a composite outcome including death and hospital-acquired pneumonia occurring from admission to day 28. The secondary endpoints were the incidence of death, the number of hospital-acquired pneumonia, mechanical ventilation-free days and intensive care unit-free day at day 28. RESULTS: The incidence of the composite endpoint was lower in the severe hyperoxemia group(OR, 0.25; 95%CI, 0.09-0.73; P < 0.001) compared with control. The 28-day mortality incidence was lower in severe (OR, 0.23; 95%CI, 0.08-0.68; P < 0.001) hyperoxemia group (OR, 0.41; 95%CI, 0.17-0.97; P = 0.04). Significant association was found between hyperoxemia and secondary outcomes. CONCLUSION: In our cohort early hyperoxemia during the first 24 h of admission after severe blunt chest trauma was not associated with worse outcome.
