【摘要】:目的研究鎮(zhèn)痛鎮(zhèn)靜對(duì)重型腦損傷患者早期心率變異性(HRV)及血清兒茶酚胺的影響,明確重型腦損傷患者早期使用鎮(zhèn)痛鎮(zhèn)靜劑的安全性及有效性。方法單中心、前瞻性、非隨機(jī)對(duì)照、開(kāi)放研究。收集起病48h內(nèi)入住外科重癥病房(SICU)的重型腦損傷患者34例為研究對(duì)象,其中鎮(zhèn)靜組15例在入住SICU后即予咪達(dá)唑侖及舒芬太尼持續(xù)鎮(zhèn)痛鎮(zhèn)靜,非鎮(zhèn)靜組19例按SICU常規(guī)治療。連續(xù)3d監(jiān)測(cè)所有患者同一時(shí)間段24h動(dòng)態(tài)心電圖;連續(xù)4d檢測(cè)所有患者每天8:00血兒茶酚胺(腎上腺素、去甲腎上腺素)水平。收集同期24例體檢者作為對(duì)照組。結(jié)果鎮(zhèn)靜組及非鎮(zhèn)靜組的血清兒茶酚胺的水平與正常參考值比較均升高(P0.05),非鎮(zhèn)靜組兒茶酚胺水平較鎮(zhèn)靜組高,但差別無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。鎮(zhèn)靜組和非鎮(zhèn)靜組的HRV各指標(biāo)水平均明顯小于對(duì)照組(P0.05)。短期預(yù)后評(píng)估中鎮(zhèn)靜組的昏迷天數(shù)、總住院時(shí)間均明顯小于非鎮(zhèn)靜組(P0.05)。結(jié)論重型腦損傷可引起血清兒茶酚胺升高及自主神經(jīng)功能紊亂。鎮(zhèn)痛鎮(zhèn)靜可以改善自主神經(jīng)功能紊亂,減少兒茶酚胺分泌,改善短期預(yù)后,但仍需大樣本的研究以證實(shí)。
[Abstract]:Objective to study the effects of analgesia and sedation on heart rate variability (HRV) and serum catecholamine in patients with severe brain injury, and to determine the safety and efficacy of early use of analgesic sedatives in patients with severe brain injury. Methods single center, prospective, non-randomized controlled open trial. Thirty-four patients with severe brain injury admitted to surgical intensive care unit (SICU) within 48 hours were selected as study subjects. 15 patients in sedation group were treated with midazolam and sufentanil after admission to SICU, 19 patients in non-sedative group were treated with routine therapy in SICU. The serum catecholamine (epinephrine, norepinephrine) levels were measured at 8:00 for 4 consecutive days. 24 cases of physical examination in the same period were collected as control group. Results the levels of serum catecholamine in sedation group and non-sedative group were higher than those in normal control group (P 0.05). The level of catecholamine in non-sedative group was higher than that in sedative group, but the difference was not statistically significant (P 0.05). The levels of HRV in sedation group and non-sedative group were significantly lower than those in control group (P 0.05). The duration of coma in sedation group was significantly shorter than that in non-sedative group (P 0.05). Conclusion severe brain injury can cause serum catecholamine elevation and autonomic nervous dysfunction. Analgesia and sedation can improve autonomic nervous dysfunction, reduce catecholamine secretion and improve short-term prognosis.
