Airway management in anesthesia for thoracic surgery: a "real life" observational study.

ABSTRACT: 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. Results:Malposition rate for DLTs was 14%, for BBs 33%. DLTs were used in 95% of patients and BBs in 5%. Mean positioning time was shorter for DLT than BB (156±230 vs. 321±290 s). BRO was used in 54% of patients to check the correct positioning of the DLT. Desaturation occurred in 20% of all cases during OLV achieved through a DLT. Predicting factors of desaturation were dislocation (OR 2.03) and big size of DLT (OR 1.15). BRO use (OR 0.69) and left surgical side (OR 0.41) proved to be protective factors. Difficult airway prevalence was 16%; 10.8% predicted and 5.2% unpredicted. 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. Left procedures and BRO use could lead to fewer episodes of desaturation.

Project description:Background and objectiveThoracic surgery causes significant pain which can negatively affect pulmonary function and increase risk of postoperative complications. Effective analgesia is important to reduce splinting and atelectasis. Systemic opioids and thoracic epidural analgesia (TEA) have been used for decades and are effective at treating acute post-thoracotomy pain, although both have risks and adverse effects. The advancement of thoracoscopic surgery, a focus on multimodal and opioid-sparing analgesics, and the development of ultrasound-guided regional anesthesia techniques have greatly expanded the options for acute pain management after thoracic surgery. Despite the expansion of surgical techniques and analgesic approaches, there is no clear optimal approach to pain management. This review aims to summarize the body of literature regarding systemic and regional anesthetic techniques for thoracic surgery in both thoracotomy and minimally invasive approaches, with a goal of providing a foundation for providers to make individualized decisions for patients depending on surgical approach and patient factors, and to discuss avenues for future research.MethodsWe searched PubMed and Google Scholar databases from inception to May 2021 using the terms "thoracic surgery", "thoracic surgery AND pain management", "thoracic surgery AND analgesia", "thoracic surgery AND regional anesthesia", "thoracic surgery AND epidural". We considered articles written in English and available to the reader.Key content and findingsThere is a wide variety of strategies for treating acute pain after thoracic surgery, including multimodal opioid and non-opioid systemic analgesics, regional anesthesia including TEA and paravertebral blocks (PVB), and a recent expansion in the use of novel fascial plane blocks especially for thoracoscopy. The body of literature on the effectiveness of different approaches for thoracotomy and thoracoscopy is a rapidly expanding field and area of active debate.ConclusionsThe optimal analgesic approach for thoracic surgery may depend on patient factors, surgical factors, and institutional factors. Although TEA may provide optimal analgesia after thoracotomy, PVB and emerging fascial plane blocks may offer effective alternatives. A tailored approach using multimodal systemic therapies and regional anesthesia is important, and future studies comparing techniques are necessary to further investigate the optimal approach to improve patient outcomes.

Project description:Objective Emergence from anesthesia starts from the limbic structures and then spreads outwards to brainstem, reticular activating systems, and then to the cortex. Epilepsy surgery often involves resection of limbic structures and hence may disrupt the pattern of emergence. The aim of this study was to explore the pattern of emergence from anesthesia following epilepsy surgery and to determine associated variables affecting the emergence pattern. Setting and Design Tertiary care center, prospective observational study. Materials and Methods We conducted a prospective observation pilot study on adult patients undergoing anterior temporal lobectomy and amygdalohippocampectomy for epilepsy. Anesthesia management was standardized in all patients, and they were allowed to wake up with "no touch" technique. Primary outcome of the study was the pattern of emergence (normal emergence, agitated emergence, or slow emergence) from anesthesia. Secondary outcomes were to explore the differences in preoperative neuropsychological profile and limbic structure volumes between the different patterns of emergence. Quantitative variables were analyzed using Student's t -test. Qualitative variables were analyzed using chi-square test. Results Twenty-nine patients completed the study: 9 patients (31%) had agitated emergence, and 20 patients had normal emergence. Among the agitated emergence, 2 patients had Riker scale of 7 indicating violent emergence. Patient demographics, anesthetic used, neuropsychological profile, and limbic structure volumes were similar between normal emergence and agitated emergence groups. However, two patients who had severe agitation (Riker scale of 7) had the lowest intelligence quotient. Conclusion Our pilot study showed that emergence agitation is not uncommon in patients undergoing epilepsy surgery. However, due to smaller sample size, the role of preoperative neuropsychologic profile and hippocampal volumes in predicting the pattern of emergence is inconclusive.

Project description:PurposePostoperative complications after major liver surgery are common. Thoracic epidural anesthesia may provide beneficial effects on postoperative outcome. We strove to compare postoperative outcomes in major liver surgery patients with and without thoracic epidural anesthesia.MethodsThis was a retrospective cohort study in a single university medical center. Patients undergoing elective major liver surgery between April 2012 and December 2016 were eligible for inclusion. We divided patients into two groups according to whether or not they had thoracic epidural anesthesia for major liver surgery. The primary outcome was postoperative hospital length of stay, i.e., from day of surgery until hospital discharge. Secondary outcomes included 30-day postoperative mortality and major postoperative complications. Additionally, we investigated the effect of thoracic epidural anesthesia on perioperative analgesia doses and the safety of thoracic epidural anesthesia.ResultsOf 328 patients included in this study, 177 (54.3%) received thoracic epidural anesthesia. There were no clinically important differences in postoperative hospital length of stay (11.0 [7.00-17.0] vs. 9.00 [7.00-14.0] days, p = 0.316, primary outcome), death (0.0 vs. 2.7%, p = 0.995), or the incidence of postoperative renal failure (0.6 vs. 0.0%, p = 0.99), sepsis (0.0 vs. 1.3%, p = 0.21), or pulmonary embolism (0.6 vs. 1.4%, p = 0.59) between patients with or without thoracic epidural anesthesia. Perioperative analgesia doses - including the intraoperative sufentanil dose (0.228 [0.170-0.332] vs. 0.405 [0.315-0.565] μg·kg-1·h-1, p < 0.0001) - were lower in patients with thoracic epidural anesthesia. No major thoracic epidural anesthesia-associated infections or bleedings occurred.ConclusionThis retrospective analysis suggests that thoracic epidural anesthesia does not reduce postoperative hospital length of stay in patients undergoing major liver surgery - but it may reduce perioperative analgesia doses. Thoracic epidural anesthesia was safe in this cohort of patients undergoing major liver surgery. These findings need to be confirmed in robust clinical trials.

Project description:Background and objectiveSurgical procedures involving incisions of the chest wall regularly pose challenges for intra- and postoperative analgesia. For many decades, opioids have been widely administered to target both, acute and subsequent chronic incisional pain. Opioids are potent and highly addictive drugs that can provide sufficient pain relief, but simultaneously cause unwanted effects ranging from nausea, vomiting and constipation to respiratory depression, sedation and even death. Multimodal analgesia consists of the administration of two or more medications or analgesia techniques that act by different mechanisms for providing analgesia. Thus, multimodal analgesia aims to improve pain relief while reducing opioid requirements and opioid-related side effects. Regional anesthesia techniques are an important component of this approach.MethodsFor this narrative review, authors summarized currently used regional anesthesia techniques and performed an extensive literature search to summarize specific current evidence. For this, related articles from January 1985 to March 2022 were taken from PubMed, Web of Science, Embase and Cochrane Library databases. Terms such as "pectoral nerve blocks", "serratus plane block", "erector spinae plane block" belonging to blocks used in thoracic surgery were searched in different combinations.Key content and findingsPotential advantages of regional anesthesia as part of multimodal analgesia regiments are reduced surgical stress response, improved analgesia, reduced opioid consumption, reduced risk of postoperative nausea and vomiting, and early mobilization. Potential disadvantages include the possibility of bleeding related to regional anesthesia procedure (particularly epidural hematoma), dural puncture with subsequent dural headache, systemic hypotension, urine retention, allergic reactions, local anesthetic toxicity, injuries to organs including pneumothorax, and a relatively high failure especially with continuous techniques.ConclusionsThis narrative review summarizes regional anesthetic techniques, specific indications, and clinical considerations for patients undergoing thoracic surgery, with evidence from studies performed. However, there is a need for more studies comparing new block methods with standard methods so that clinical applications can increase patient satisfaction.
