Background: One-lung ventilation (OLV) in thoracic anesthesia is required to provide good surgical exposure. OLV is commonly achieved through a double lumen tube (DLT) or a bronchial blocker (BB). Malposition is a relevant issue related to these devices use. No prospective studies with adequately large sample size have been performed to evaluate the malposition rate of DLTs and BBs. Methods: A total of 2,127 patients requiring OLV during thoracic surgery were enrolled. The aim of this multicenter prospective observational study performed across 26 academic and community hospitals is to evaluate intraoperative malposition rate of DLTs and BBs. We also aim to assess: which device is the most used to achieve OLV, the frequency of bronchoscope (BRO) use, the incidence rate of desaturation during OLV and the role of other factors that can correlate to this event, and incidence of difficult airway. Conclusions: DLT has a low malpositioning rate and is the preferred device to achieve OLV. BRO use recorded was unexpectedly low. The possibility of encountering a difficult airway is frequent, with an overall prevalence of 16%. Risk factors of desaturation are malposition and increased size of DLT. Minor thoracic surgery, left procedures, and BRO use could lead to fewer episodes of desaturation.

: OBJECTIVES: The endotracheal tube (ETT) and the laryngeal mask airway (LMA) are possible strategies for airway management during tracheal resection and reconstruction for tracheal and laryngotracheal stenosis. The goal of the study was to analyse and compare outcomes in the LMA and ETT groups. METHODS: Between 2003 and 2020, a total of 184 patients affected by postintubation, post-tracheostomy and idiopathic stenosis who had tracheal or laryngotracheal resections and reconstructions via a cervicotomy were retrospectively enrolled in this single-centre study. In 29 patients, airway management was achieved through LMA during tracheal surgery, whereas in 155 patients, it was achieved through ETT. A case–control matching analysis was performed with a 1:1 ratio, according to age, gender, body mass index, aetiology and length of stenosis (1–4 cm), resulting in 22 patients managed through LMA (LMA group) matched with 22 patients managed through ETT (ETT group). RESULTS: No significant differences were found in the reintubation rate, 30-day mortality and postoperative length of stay. Operative time was shorter in patients with LMA (96.23 ± 34.72 min in the ETT group vs 76.14 ± 26.94 min in the LMA group; P = 0.043). Intensive care unit (ICU) admission rate and stay were lower in the LMA group [18 in the ETT group vs 8 in the LMA group, odds ratio = 10.17, confidence interval (CI) 95% 1.79–57.79; P = 0. 009; 22.77 ± 16.68 h in ETT group vs 9.23 ± 13.51 h in LMA group; P = 0.005]. Dysphonia was more frequent in the ETT group than in the LMA group (20 in the ETT group vs 11 in the LMA group, odds ratio = 13.79, CI 95% 1.86–102; P = 0.010). CONCLUSIONS: LMA is a feasible option for airway management in tracheal surgery, with lower operative time, ICU admission rate, ICU length of stay and postoperative dysphonia occurrence.

Background: Breast cancer surgery is usually managed using opioid-inclusive anesthesia (OIA), although opioids are associated with several adverse events, including nausea, vomiting, and constipation. Multimodal opioid-free anesthesia (OFA) has been introduced to reduce the incidence of these side effects. In this single-center retrospective study, we investigated whether ketamine, combined with magnesium and clonidine, could effectively control postoperative pain in patients undergoing quadrantectomy, while reducing postoperative nausea and vomiting (PONV). Results: A total of 89 patients submitted to quadrantectomy were included and divided into an OFA group (38 patients) and an OIA group (51 patients) according to the received anesthetic technique. Analgesia in the OIA group was based on an intraoperative infusion of remifentanil, and analgesia in the OFA consisted of an intraoperative infusion of ketamine and magnesium sulfate. Postoperative pain in both groups was managed with nonsteroidal anti-inflammatory drugs (NSAIDs) and paracetamol. Postoperative pain, assessed with the numeric rating scale (NRS), requirements for additional analgesics, the incidence of PONV, and patient satisfaction evaluated using a QoR-40 questionnaire were compared between the two groups. Levels of pain at 30 min and 6, 12, and 24 h after surgery; number of paracetamol rescue doses; and the incidence of PONV were lower in the OFA group (p <0.05). Patient satisfaction was comparable in the two groups. Conclusions: A combination of ketamine, magnesium, and clonidine could be more effective than opioid-based analgesia in reducing postoperative pain and lowering PONV occurrence after quadrantectomy for breast cancer.
