We aim to provide evidence that despite not administering epinephrine, (1) the amount of hemorrhaging during surgery will not change, (2) surgery time will not increase and may even be shorter, and (3) there would be fewer cardiovascular-related consequences.
One hundred thirteen patients were enrolled and randomized into the control (n = 74) and intervention groups (n = 39). During the primary open or closed rhinoplasty operation, anesthesia was managed by continual infusion of remifentanil (14-20 μg/h) and propofol (4-6 mg/kg/h) with an infusion pump, in addition to N(2)O-O(2) (50%). Atracurium was repeated (5 mg every 20 min). Patients in the control group received an epinephrine (1/100,000) injection to the nose, and patients in the intervention group did not. All patients received dexamethasone (8 mg IV) and metoclopramide (10 mg IV). At the end of the operation and before extubation, the muscle relaxants were reversed with prostigmine (0.35 mg/kg) and atropine (0.175 mg/kg).
We found (1) no statistically significant association between epinephrine injection and hemorrhage during or after surgery (P = 0.949), (2) a statistically significant association between epinephrine injection and complications, and (3) the group that did not receive the injection had fewer complications (P = 0.01). With respect to the duration of surgery, we did not detect any statistically significant associations between the groups.
Elimination of epinephrine during rhinoplasty as an alternative procedure may lead to the same surgery outcomes if not a better one. Studies with a larger sample size are needed to further substantiate these findings.
我们旨在提供证据,证明即使不使用肾上腺素,(1)手术期间的出血量不会改变,(2)手术时间不会延长,甚至可能更短,(3)心血管相关并发症会更少。
将 113 名患者纳入并随机分为对照组(n=74)和干预组(n=39)。在原发性开放式或封闭式鼻整形手术中,通过输注泵持续输注瑞芬太尼(14-20μg/h)和丙泊酚(4-6mg/kg/h),并辅以 N2O-O2(50%)来管理麻醉。每隔 20 分钟重复使用阿曲库铵(5mg)。对照组患者向鼻部注射肾上腺素(1/100000),干预组患者则不注射。所有患者均接受地塞米松(8mg IV)和甲氧氯普胺(10mg IV)。手术结束时,在拔管前,用新斯的明(0.35mg/kg)和阿托品(0.175mg/kg)逆转肌肉松弛剂。
我们发现(1)肾上腺素注射与手术期间或手术后的出血之间没有统计学上的显著关联(P=0.949),(2)肾上腺素注射与并发症之间存在统计学上的显著关联,(3)未接受注射的组并发症更少(P=0.01)。至于手术持续时间,我们没有发现两组之间存在任何统计学上的显著关联。
在鼻整形术中消除肾上腺素作为替代程序,如果不是更好的程序,可能会导致相同的手术结果。需要更大样本量的研究来进一步证实这些发现。
