ABSTRACT
OBJECTIVE: This meta-analysis compared the quality of lung collapse and the resultant adverse reactions between the use of double-lumen endotracheal tubes (DLT) and bronchial blockers (BB) in minimally invasive thoracic surgery. METHODS: A search was performed in five bibliographic databases, namely PubMed, Springer, Medline, EMBASE, and Cochrane Library ignoring the original language, which identified five randomized controlled trials (RCTs) published on or before December 31, 2021. These studies were subsequently analyzed. All included studies compared the efficacy and safety of DLT and BB as a lung isolation technique in surgery. The methodological quality of each study was assessed by the Cochrane Collaboration's risk of bias tool. The quality of lung collapse and the malposition rate were adopted as the main outcome indicators. Alternatively, the intubation time and the incidence of postoperative sore throat were adopted as secondary indicators. RESULTS: When either DLT or BB were utilized in minimally invasive thoracic surgery, no differences were observed in the quality of lung collapse (odds ratio [OR], 1.00; 95% confidence interval [CI], 0.63 to 1.58), the intubation time (mean difference [MD], 0.06; 95% CI, -1.02 to 1.14), or the malposition rate (OR, 0.88; 95% CI, 0.37 to 2.06). However, the incidence of postoperative sore throat among patients treated with BB was significantly lower than that among patients treated with DLT (OR, 5.25; 95% CI, 2.55 to 10.75). CONCLUSION: When utilized in minimally invasive thoracic surgery, the quality of lung collapse with DLT was identical to that with BB. However, patients treated with the latter demonstrated a significantly lower incidence of postoperative sore throat.

Background: Ultrasound-guided internal jugular vein (IJV) catheterization has become a standard procedure as it yields a higher success rate and fewer mechanical complications compared with an anatomical landmark technique. There are several common methods for ultrasound guidance IJV catheterization, such as short-axis out-of-plane, long-axis in-plane and oblique axis in-plane, but these technologies are still developing. It is important to further study the application of different ultrasound-guided IJV puncture techniques and find an effective and safe ultrasound-guided puncture technique. Methods: A China randomized, open-label, parallel, single center, positive-controlled, non-inferiority clinical trial will evaluate 190 adult patients undergoing elective surgery and need right jugular vein catheterization. Study participants randomized in a 1:1 ratio into control and experimental groups. The control group will take the oblique axis in-plane method for IJV catheterization. The experimental group will take the Modified combined short and long axis method. The primary endpoint of the trial is the rate of one-time successful guidewire insertion without posterior wall puncture (PWP). Secondary endpoints are the number of needle insertion attempts, the total success rate, the procedure time, and mechanical complications. Conclusion: This randomized controlled trial will evaluate the effectiveness and safety of Modified combined short and long axis method and oblique axis in-plane method for right IJV catheterization in adult patients.
ABSTRACT
BACKGROUND: Endoscopic thyroidectomy has obvious advantages over conventional surgical techniques in terms of postoperative cosmetic outcome. Although the incidence of carbon dioxide embolism (CDE) during endoscopic thyroidectomy is very low, it is potentially fatal. The clinical manifestations of CDE vary, and more attention should be paid to this disorder. CASE SUMMARY: A 27-year-old man was scheduled for thyroidectomy by the transoral vestibular approach. The patient had no other diseases or surgical history. During the operation, he developed a CDE following inadvertent injury of the anterior jugular vein. The clinical manifestation in this patient was a transient sharp rise in end-tidal carbon dioxide, and his remaining vital signs were stable. In addition, loud coarse systolic and diastolic murmurs were heard over the precordium. The patient was discharged on day 4 after surgery without complications. CONCLUSION: A transient sharp rise in end-tidal carbon dioxide is considered a helpful early sign of CDE during endoscopic thyroidectomy.
ABSTRACT
BACKGROUND: Esophageal cancer is a common malignant tumor of the digestive system. At present, surgery is the most important treatment strategy. After esophagectomy and gastric esophagoplasty, the patients are prone to regurgitation. However, these patients currently do not receive much attention, especially from anesthesiologists. CASE SUMMARY: A 55-year-old woman was scheduled for right lower lung lobectomy. The patient had undergone radical surgery for esophageal cancer under general anesthesia 6 mo prior. Although the patient had fasted for > 17 h, unexpected aspiration still occurred during induction of general anesthesia. Throughout the operation, oxygen saturation was 98%-100%, but the airway pressure was high (35 cmH2O at double lung ventilation). The patient was sent to the intensive care unit after surgery. Bedside chest radiography was performed, which showed exudative lesions in both lungs compared with the preoperative image. After surgery, antibiotics were given to prevent lung infection. On day 2 in the intensive care unit, the patient was extubated and discharged on postoperative day 7 without complications related to aspiration pneumonia. CONCLUSION: After esophagectomy, patients are prone to regurgitation. We recommend nasogastric tube placement followed by rapid sequence induction or conscious intubation.
