Influence of pressure control levels on the pulse pressure variations: an animal study using healthy piglets

Pulse pressure variation (PPV) is a promising predictor for volume responsiveness. However, recent studies have criticized its validity during small tidal volume (TV) ventilation. The present study evaluated the influence of pressure control level (PCL) on PPV. Six anesthetized healthy piglets simulating hemorrhagic shock underwent five stages of intravascular volume status change. Each stage comprised four cycles of PCL manipulation. In each cycle, five different PCLs were applied in random order. Among 600 arterial pressure tracings obtained during PCL manipulations, 26 tracings were excluded because of signal artifact or ectopic beats. For the remaining 574 tracings, the percentage of normal beats among total recorded beats in each tracing was 99.80% ± 0.85%. When manipulating PCL causing an abrupt change within -16 ～ +8 cmH(2)O, the PPV responded rapidly and stabilized within 60 s after manipulation. With higher increment in PCL (+12 ～ +16 cmH(2)O), it required 90 s for PPV to stabilize. Under each cycle of PCL manipulation, the PPVs are linearly correlated to the PCL (r = 0.84 ± 0.21) and TV (r = 0.83 ± 0.22). The PPV as well as the slopes of the trend lines decreased from hypovolemic stages toward hypervolemic stages. Pulse pressure variation responds rapidly to change in ventilator setting and is linearly correlated with the PCL and TV. These characteristics may have important applications in critical care to improve the interpretation of PPV in accord to different ventilator settings.     

小柴胡汤加味联合经鼻肠梗阻导管对粘连性肠梗阻治疗效果

目的:对小柴胡汤加味联合经鼻肠梗阻导管治疗粘连性肠梗阻的效果行回顾性分析。方法:按纳入标准收集湖南中医药大学第一附属医院普外微创科于2018年4月至2019年4月期间符合粘连性肠梗阻诊断的患者50例。随机分为2组,对照组(25例)和实验组(25例)。对照组行经鼻肠梗阻导管置入术治疗,术后予以常规治疗,实验组在常规治疗的基础上给予了小柴胡汤加味方治疗。2组均3天复查一次相关实验室指标。比较两组排气排便恢复时间、开始进食时间、导管的拔除时间、住院时间等指标,并比较两组患者炎性指标变化以及治疗结果。结果:对照组患者平均的排气排便恢复时间、腹痛腹胀消失时间、进食时间、气液平消失时间、导管拔除时间、平均住院时间普遍长于实验组;实验组患者治疗后白细胞(WBC)计数、C反应蛋白(CRP)、白细胞介素-6(IL-6)、白细胞介素-8(IL-8)等炎性指标的水平较对照组明显降低;实验组的总有效率高于对照组。结论:小柴胡汤加味联合经鼻肠梗阻导管对治疗粘连性肠梗阻比单纯使用经鼻肠梗阻导管治疗效果好。     

肘部高能量创伤术后应用带铰链外固定架在早期康复中的优越性

目的:探讨肘部高能量创伤术后应用带铰链外固定架在早期康复中的作用。方法:选择2000-10/2004-06华西医院骨科收治肘部高能量创伤、同时接受内、外固定的患者78例。患者均知情同意。男43例,女35例,肱骨髁上粉碎性骨折13例,肱骨髁上髁间粉碎性骨折21例,Monteggia’s骨折26例,尺骨鹰嘴粉碎性骨折9例,尺骨冠突骨折5例,桡骨小头粉碎性骨折4例;合并环状韧带损伤17例,尺侧副韧带损伤25例,桡侧副韧带损伤8例;开放性骨折17例,闭合骨折61例。分为外固定架组35例,石膏、支具组43例,两组年龄、性别等无统计学差异。外固定架组患者术后3d开始在外固定架保护下进行肘关节屈伸活动;石膏、支具组术后4～6周拆除石膏、支具后开始活动。随访时观察患者骨折愈合情况;两组患者肘关节活动度及Gassebaum评分分级结果。采用Gassebaum分级指标评价治疗后肘关节功能恢复效果,优,肘关节无症状,伸肘15°,屈肘130°;良:肘关节有主观不适症状,伸肘30°,屈肘120°;可:肘关节有轻微不适症状,伸肘40°,屈肘90°～120°;差:关节功能受限,伸肘40°,屈肘<90°。肘关节活动度=屈曲角度-伸直角度。结果:78例患者平均随访14个月,均进入结果分析。①患者骨折愈合情况:术后3～6个月X射线片证实骨折愈合,内固定物无松动断裂,外固定架组无钉道感染和螺钉松动、断裂发生。②两组患者肘关节活动度及Gassebaum评分分级结果:术后3和6个月,外固定架组在术后肘关节功能恢复上好于石膏、支具组[(96±18)°比(55±14)°,(105±16)°比(74±21)°,t=10.835～7.386,P<0.05],外固定架组优良率为88.6%,石膏、支具组为58.1%。结论:①肘部高能量创伤以后,介入功能康复训练时间越早,越有利于肘关节活动度的恢复。②应用铰链外固定架在肘部高能量创伤术后对患者早期肘关节功能恢复比石膏、支具更有优越性。
