ObjectiveTo compare the clinical data of pulmonary lobectomy in patients with massive hemoptysis of pulmonary tuberculosis after bronchial artery embolization in the short and long term, so as to provide a reference for clinical choices of appropriate operation time.MethodsA retrospective analysis was conducted on 33 patients with massive hemoptysis of pulmonary tuberculosis, who had received pulmonary lobectomy after bronchial artery embolization in Wuhan Pulmonary Hospital from January 2015 to November 2017, including 29 males and 4 females aged of 23-66 (52.64±9.70) years. According to the time interval between bronchial artery embolization and lobectomy, the patients were divided into a short-term group (<2 weeks, 14 patients) and a long-term group (>1 month, 19 patients). The clinical data, such as operation time, intraoperative blood loss, postoperative extubation time and serious postoperative complications, were observed in the two groups for statistical analysis.ResultsThe operative time (297.13±75.69 min vs. 231.32±67.57 min, P=0.013), intraoperative blood loss (685.74±325.51 mL vs. 355.83±259.11 mL, P=0.002), postoperative extubation time (14.07±5.24 d vs. 8.90±3.57 d, P=0.003) of the short-term group were all higher than those in the long-term group.ConclusionFor the patients with massive hemoptysis of pulmonary tuberculosis, who had surgical indications and no risk of early rebleeding after bronchial artery embolization, pulmonary lobectomy should be performed late until the patient's physical condition and the primary disease was stable.
Objective To evaluate the association between pressure-controlled ventilation-volume guaranteed (PCV-VG) mode and volume-controlled ventilation (VCV) mode on postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung resection. Methods A retrospective cohort analysis of 329 patients undergoing elective thoracoscopic lung resection in West China Hospital of Sichuan University between September 2020 and March 2021 was conducted, including 213 females and 116 males, aged 53.6±11.3 years. American Society of Anesthesiologists (ASA) grade wasⅠ-Ⅲ. The patients who received lung-protective ventilation strategy during anesthesia were divided into a PCV-VG group (n=165) and a VCV group (n=164) according to intraoperative ventilation mode. Primary outcome was the incidence of PPCs during hospitalization. Results A total of 73 (22.2%) patients developed PPCs during hospitalization. The PPCs incidence of PCV-VG and VCV was 21.8% and 22.6%, respectively (RR=0.985, 95%CI 0.569-1.611, P=0.871). Multivariate logistic regression analysis showed that there was no statistical difference in the incidence of PPCs between PCV-VG and VCV mode during hospitalization (OR=0.846, 95%CI 0.487-1.470, P=0.553). Conclusion Among patients undergoing thoracoscopic lung resection, intraoperative ventilation mode (PCV-VG or VCV) is not associated with the risk of PPCs during hospitalization.
在过去二十年间，麻醉技术和手术技术的改进使肺部恶性肿瘤患者的手术死亡率大大降低，但术后并发症仍是主要问题。肺切除术后的常见并发症是肺部并发症[1]，主要表现是低氧血症，尤其在肺功能减退的肺切除患者中发病率更高[2]。目前国内对低氧血症的诊断缺乏统一的诊断标准，一些作者采用Russell等[3]提出的标准，吸空气氧的情况下，患者动脉血氧饱和度（SpO2）≤92%，大于30 s就可诊断为术后低氧血症。也有作者建议[4]将一次或以上血气检查PaO2lt;8 kPa或PaO2/FiO2lt;300 mm Hg（1 mm Hg=0.133 kPa）作为诊断低氧血症的标准。30%~50%的术后患者可发生低氧血症，一般认为这样的低氧血症是一过性的，对大多数患者是无害的[5]。但如果合并心脑或其他器官动脉硬化或其他原因的血管阻塞，这种低氧血症就是很危险的[6]。常见低氧血症的原因是肺萎陷不张和误吸、心源性肺水肿、静脉输入液体过量、通气血流比例失调和急性肺损伤/急性呼吸窘迫综合征（ALI/ARDS）[7]，其中ALI/ARDS是肺切除术后患者死亡的主要原因[8-10]。
