摘要:

目的 比较超声引导下椎旁神经阻滞复合全身麻醉对胸科手术血流动力学及恢复期的影响。 方法 择期胸科手术患者80例, ASA分级Ⅱ、Ⅲ级。按随机数字表法分为2组,椎旁神经阻滞复合全身麻醉组(TPVB组)和传统全身麻醉对照组(C组),每组40例。两组患者采用相同麻醉诱导,术中采用七氟醚吸入,丙泊酚及瑞芬太尼静脉泵注维持麻醉。观察术前(T0)、诱导后(T1)、手术开始3 min(T2)、手术结束后(T3)的血流动力学参数,需要血管活性药物干预的次数及镇痛药物用量;记录麻醉时间、手术时间、苏醒时间(呼之睁眼时间)、拔管时间及疼痛评分;采用镇静-觉醒(Observer′s Assessment of Alertness/Sedation Scale, OAA/S)评分评价恢复期意识状态。 结果 TPVB组T2时SBP、DBP、心率明显低于C组,T3时SBP、DBP明显高于C组,心率明显低于C组(P<0.05)。TPVB组4种血管活性药物使用次数及瑞芬太尼的用量明显少于C组(P<0.05)。TPVB组术毕呼之睁眼时间、拔管时间及疼痛评分均明显优于C组(P<0.05),呼之睁眼时、拔管前、拔管后的OAA/S评分均明显高于C组(P<0.05)。 结论 椎旁神经阻滞复合全身麻醉可以使胸科手术患者血流动力学更加平稳,加速术后拔管时间,降低术后疼痛评分。

Abstract:

Objective To compare the effects of combined paravertebral nerve block and general anesthesia on hemodynamics and recovery period in thoracic surgery. Methods Eighty patients undergoing elective thoracic surgery with American Society of Anesthesiologists(ASA) Ⅱ or Ⅲ were randomly divided into 2 groups with 40 cases in each group. Paravertebral nerve block combined general anesthesia group (TPVB group) and traditional general anesthesia control group (C group). Two groups of patients were induced with the same procedure. Sevoflurane inhalation, propofol, and remifentanil were administered intravenously to maintain anesthesia. Hemodynamic parameters before surgery (T0), after induction (T1), 3 min after the operation (T2), after the end of surgery (T3) and the number of interventions requiring vasoactive drugs and dosage of analgesic drugs were measured. The time of anesthesia, operation time, and recovery time, extubation time and pain score were recorded. The recovery of consciousness was assessed by using Observer′s Assessment of Alertness/Sedation Scale (OAA/S) score. Results Systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate were significantly lower in TPVB group than in group C at the T2 timepoint. SBP and DBP were significantly higher, and heart rate was significantly lower in TPVB group than in group C at the T3 timepoint (P<0.05). The number of 4 vasoactive drugs and remifentanil dosage were significantly less in TPVB group than in group C (P<0.05). The time of blinking, extubating time and pain score of TPVB group were significantly better than those of group C (P<0.05). Postoperative opening the eyes by prompting time, extubating time, and pains cores were significantly better in TPVB group than in group C (P<0.05). The OAA/S scores before and after extubating were significantly higher in TPVB group than in group C (P<0.05). Conclusions Combination of paravertebral nerve block with general anesthesia leads to more stable hemodynamics, earlier time for extubation, and less postoperative pain scores in patients undergoing thoracic surgery.
