电视辅助胸腔镜下解剖性肺切除治疗I期肺癌的临床效果

目的 探讨电视辅助胸腔镜下解剖性肺切除治疗Ⅰ期肺癌的临床效果。方法 采用回顾性研究方法,选取2015年5月至2017年1月广西医科大学附属肿瘤医院收治的I期肺癌患者84例,按照手术方法不同将患者分为两组:观察组和对照组,每组各42例。观察组患者实施电视辅助胸腔镜下解剖性肺切除术治疗,对照组患者给予传统开胸肺叶切除术治疗。比较两组患者的住院时间、切口长度、术中出血量、手术时间、1年和3年生存情况及生活质量评分(SF-36生活量表)变化。结果 观察组患者的住院时间短于对照组(6. 13±1. 46 vs. 10. 39±2. 41 d),切口长度小于对照组(4. 38±1. 09 vs. 11. 84±3. 25 cm),术中出血量少于对照组(284. 62±54. 21 vs. 397. 57±61. 49 ml),差异均具有统计学意义(P <0. 05);而两组手术时间比较(165. 28±33. 24 vs. 156. 39±30. 92 min),差异无统计学意义(P> 0. 05)。观察组患者的1、3年生存率[97. 62%(41/42)、90. 48%(38/42)]均高于对照组[88. 10%(37/42)、76. 19%(32/42)],但差异无统计学意义(P> 0. 05)。观察组患者的各项生活质量评分[精神健康(75. 42±6. 87 vs 61. 30±4. 15分)、情感职能(81. 38±7. 15 vs. 73. 49±5. 76分)、社会功能(82. 67±5. 78 vs. 75. 42±4. 35分)、一般健康状况(79. 49±6. 17 vs.70. 31±5. 04分)、精力(84. 37±5. 45 vs. 74. 13±6. 07分)、生理职能(86. 52±6. 88 vs. 76. 93±6. 42分)、躯体疼痛(83. 46±7. 49 vs. 74. 33±5. 79分)、生理功能(70. 39±4. 31 vs. 61. 38±3. 56分)]均高于对照组,且差异具有统计学意义(P <0. 05)。结论 与传统开胸肺叶切除术相比,电视辅助胸腔镜下解剖性肺切除治疗I期肺癌手术损伤更小、短期生存率更高,且有助于提高患者术后生活质量水平,这对改善患者预后有重要意义,值得临床推广应用。     

电针复合TCI靶控输注在单肺通气食管癌开胸手术麻醉中的应用与安全性＊

目的 探讨电针复合靶控输注（Target Controlled Infusion， TCI）在单肺通气食管癌开胸手术麻醉中的应用价值。方法 选取于我院拟行单肺通气食管癌开胸切除手术患者60例作为研究对象。随机将其分为试验组与对照组，对照组30例采取气管插管全麻及TCI靶控输注维持麻醉深度，试验组30例则在对照组方案基础上辅助电针麻醉，记录两组患者手术麻醉时间、药物用量、苏醒时间、并发症；以及术前（T_Ⅰ）、插管前即刻（T_Ⅱ）、插管后1 min（T_Ⅲ）、切皮即刻（T_Ⅳ）、去骨时（T_Ⅴ）、拔管即刻（T_Ⅵ）时平均动脉压（MAP）、平均心率（HR）、BIS值；术前、术后1天、术后3天简易智能精神状态检查量表（MMSE）；并于麻醉诱导前（T₀）、手术开始2 h（T₁）、术后1天（T₂）、术后3天（T₃）时抽取患者外周静脉血检测IL-1β、IL-6、IL-10、TNF-α浓度。结果 试验组手术用时、麻醉时间略低于对照组，但差异无统计学意义（P>0.05），试验组异丙酚、舒芬太尼用量以及苏醒时间均明显低于对照组（P<0.05）；T_Ⅱ时两组平均动脉压（Mean Arterial Pressure， MAP）、心率（Heartrate， HR）较术前明显降低，且试验组MAP明显低于对照组（P<0.05），但两组T_Ⅱ时HR比较无显著差异（P>0.05）；T_Ⅲ、T_Ⅵ时对照组MAP、HR明显高于T_Ⅰ时，而试验组MAP、HR与T_Ⅰ比较无显著差异（P>0.05）。术后1天、3天试验组简易智能精神状态检查量表（Mini-Mental State Examination， MMSE）评分低于对照组，有显著性差异（P<0.05）。T₁、T₂、T₃时试验组白介素-1β（IL-1β）、白介素-6（IL-6）、肿瘤坏死因子（Tumor Necrosis Factor-α， TNF-α）水平明显低于对照组（P<0.05），白介素-10（IL-10）水平明显高于对照组（P<0.05）。结论 采用电针复合TCI靶控输注麻醉方案可有效提升单肺通气食管癌开胸手术麻醉效果，能够降低患者术后认知功能障碍发生风险。     

Pericardial effusion following pulmonary resection

Objective Postoperative pericardial effusion commonly occurs after open heart surgery. However, after general thoracotomy such as pulmonary resection, there have been few reports of pericardial effusion. The purpose of this study is to investigate patients with pericardial effusion following pulmonary resection.Methods: Among 2,385 patients with pulmonary resection for lung neoplasm in our institute, eight patients, whose pericardium had never been opened during the operation, developed pericardial effusion. The clinical characteristics of the eight patients were analyzed.Results: Pericardial effusion after pulmonary resection was divided into two subtypes: pericardial effusion in three patients with left thoracotomy occurring within 30 days postoperatively, and pericardial effusion in the remaining five patients with right thoracotomy occurring more than 30 days postoperatively. Pericardiotomy or pericardiocentesis was performed in three symptomatic patients, and the remaining five asymptomatic patients were treated with diuretics. Pericardial effusion disappeared in three of the five patients about 1–3 months after the conservative treatment, while, in the remaining patients, because pericardial effusion had increased gradually, pericardiocentesis was performed.Conclusion: From our experience, the treatment strategy of drainage for early pericardial effusion and diuretics for late pericardial effusion seems to be appropriate.

Left thoracotomy approach in reoperative off-pump coronary revascularization

Objective: Reoperative coronary bypass grafting is at high risk. Particularly in redo cases where the patent graft is running near the midline of the sternum, the graft may be exposed to injury by a median sternotomy and subsequent dissection. Whereas, off-pump bypass grafting from the left axillary artery or descending thoracic artery by a left thoracotomy approach is safe for preventing graft damage.Methods: From March 1998 to February 2002, we performed off-pump coronary artery bypass grafting by a left thoracotomy approach in 9 patients. The left axillary artery was used as the inflow vessel in 4 cases, and the descending thoracic, aorta in 5.Results: The radial artery was anastomosed proximally to the axillary artery in 4 cases and the descending thoracic aorta in one case. The saphenous vein graft was anastomosed, proximally to the descending thoracic aorta in 4 cases. Transdiaphragmatic minimally invasive bypass grafting for the right coronary artery was simultaneously performed in 3 cases. Postoperative cardiac events were ventricular arrhythmia in 6 cases and supraventricular arrhythmia in 3 cases. There was no damage to the patent grafts. Postoperative coronary angiography performed, in 8 cases revealed all the grafts to be patent without stenosis. Cardiac symptoms were not found after the operation in any of the cases.Conclusions: These procedures can prevent the injury to patent grafts caused by a median sternotomy, and will be one of the useful strategies for reoperative off-pump coronary artery bypass grafting.     

Clinical studies on the transabdominal resection of esophagocardial cancer and cervical anastomosis using bypass methods. Analysis of data on 76 patients

Transabdominal resection for esophagocardial cancer and reestablishment of alimentary continuity using bypass methods were performed in 76 patients. Thirteen underwent a bypass with a gastric tube and in 30, a colonic segment was prepared. In the remaining 33, a jejunal segment was used as a bypass organ, with considerable success. The 5 year survival rates were 68.8 per cent in those with stages (I+II), 16.5 per cent in those with stage III, 12.6 per cent in those with stage IV and 22.5 per cent in all cases, indicating similar results compared to those with cancer located in the upper third of the stomach with the limited proximal extension within the esophagocardial junction and operated on during the same period.     

不同镇痛方式在开胸术后的镇痛效果及对肺功能影响

目的观察不同镇痛方式在开胸手术后的镇痛效果及其对肺功能的影响。方法39例ASAⅠ~Ⅱ级,在硬膜外复合全身麻醉下行侧开胸手术的病人,术后随机接受罗哌卡因(罗哌组,n=10)、甲磺酸罗哌卡因(甲罗组,n=10)和布比卡因(布比组,n=10)硬膜外镇痛(patient controlled epidural analgesia,PCEA)及吗啡(吗啡组,n=9)静脉镇痛(patient controlled intravenous analgesia,PCIA)。结果术后1、2、5d静息时的疼痛评分罗哌组和甲罗组均明显低于布比组,但与吗啡组相比无明显差异;术后1d静息时疼痛评分吗啡组也明显低于布比组,但术后2、5d两组间无明显差异。术后1、2、5d咳嗽时疼痛评分罗哌组均明显低于布比组和吗啡组;各时间咳嗽时疼痛评分布比组和吗啡组之间无明显差异。术后1、2dPaCO2罗哌组均明显低于布比组,术后1dPaCO2罗哌组也明显低于布比组;术后1、2dPaCO2罗哌组均明显高于吗啡组,但与布比组之间无明显差异。术后1、2、5d用力肺活量和呼吸峰流速四组间无明显差异。结论罗哌卡因和甲磺酸罗哌卡因加舒芬太尼可安全用于开胸手术后硬膜外镇痛,其镇痛效果优于布比卡因加芬太尼硬膜外镇痛和吗啡静脉镇痛,并使术后病人维持更好的呼吸功能,且不增加副作用的发生率。     

电视胸腔镜手术与开胸手术治疗自发性气胸的比较

目的：比较电视胸腔镜手术（VATS）与开胸手术（TH）治疗自发性气胸的手术适应证。手术时间、围手术期出血量和输血量,术后胸管放置时间,住院时间及复发率等。方法：对本院施行的VATS35例患者与同期行TH26例患者进行比较,并随访2-46个月,以观察疗效,结果：VATS组手术时间,术后胸管放置时间和住院时间均较TH组明显缩短,围手术期出血量明显少于TH组,仅1例术后输血200ml,无中转开胸,两组均无并发症,死亡及术后复发。结论;电视胸腔镜手术创伤小,出血少,手术时间短,对心肺功能影响小,术后恢复快,为原发性自发性气胸,尤其是复发性,双侧性者的首选治疗,但继发性自发性气胸应选用开胸手术。

目的:探讨开胸术后呼吸衰竭的发病原因、临床特点及有效的预防、治疗方法.方法:对本院1993年1月～1999年4月开胸术后并发呼吸衰竭的发病情况及其治疗结果进行统计分析.结果:术前心肺功能异常、麻醉、手术创伤、感染、术后出血等为术后呼吸衰竭的主要原因,其发生率为3.56%(26/730),死亡率为23.1%(6/26).结论:加强围手术期呼吸道管理,减轻手术创伤,预防和正确处理术后并发症是防止呼吸衰竭的关键,及时有效的机械通气是抢救成功的最有效手段.     

开胸术后复张性肺水肿的探讨

目的：探讨开胸手术中单侧肺萎陷,术后肺复张导致急性肺水肿的发病机理、诊断治疗及预防。方法：对5例开胸术后复张性肺水肿患者进行总结,3例为胸腔镜辅助下胸膜固定术后,2周为食管癌根治术后,结果：常规单侧肺萎陷的开胸手术均可能发生轻重不一的复张性肺水肿。结论：可通过术中定期（以间隔30min为宜）肺复张以及术后渐进性肺复张等措施来减低复张性肺水肿的发生率。
