OBJECTIVE & HYPOTHESIS: Stated in the Null form: There will be no difference in primary or secondary hemorrhage rate in children undergoing tonsillectomy or adenotonsillectomy across three surgical techniques: PEAK Plasmablade, electric monopolar cautery, coblation.
Retrospective chart analysis.
Academic Medical Center: Children's Hospital.
SUBJECTS & METHODS: Electronic chart data were collected from patient's age 2-18 years who underwent tonsillectomy, with or without adenoidectomy, at a tertiary pediatric hospital between June 2011 to May 2013 by electric monopolar cautery, coblation, or PEAK PlasmaBlade. Treatment outcomes following each of these surgical approaches, relative to rate of post-operative primary and secondary bleeding, hospital admission, and emergency department visits were compared.
A total of 1780 patients that had tonsillectomy or adenotonsillectomy were evaluated. There was a significant difference in bleed rate by age with older patients having more bleeding post-procedure than their younger counterparts. There was also a difference in bleeding frequency by diagnosis. Patients with a diagnosis of OSA were less likely to experience a postoperative bleed than children with either recurrent tonsillitis or both. Significance was evident between post-op hemorrhage rate and instrumentation (χ(2) = 11.17, df = 2, p = 0.004). The majority of bleeds occurred with coblation (58.9%), while PEAK had only 17.8% and cautery 23%.
The null hypothesis was rejected. That is, PEAK PlasmaBlade was safe and effective, with statistically less postoperative bleeding and ED visits, especially when compared to coblation techniques. Coblation patients had the highest rates of postoperative bleeding.
以零假设形式表述:在接受扁桃体切除术或腺样体扁桃体切除术的儿童中,采用三种手术技术(PEAK 等离子刀、单极电灼、低温等离子消融术)的原发性或继发性出血率不会有差异。
回顾性图表分析。
学术医疗中心:儿童医院。
收集 2011 年 6 月至 2013 年 5 月期间在一家三级儿科医院接受扁桃体切除术(无论是否同时行腺样体切除术)的 2 至 18 岁患者的电子病历数据,手术方式包括单极电灼、低温等离子消融术或 PEAK 等离子刀。比较每种手术方式后的治疗结果,包括术后原发性和继发性出血率、住院情况及急诊就诊情况。
共评估了 1780 例接受扁桃体切除术或腺样体扁桃体切除术的患者。出血率在不同年龄组存在显著差异,年龄较大的患者术后出血比年龄较小的患者更多。出血频率在不同诊断之间也存在差异。诊断为阻塞性睡眠呼吸暂停(OSA)的患者术后出血的可能性低于患有复发性扁桃体炎或两者皆有的儿童。术后出血率与手术器械之间存在显著差异(χ(2)=11.17,自由度=2,p=0.004)。大多数出血发生在低温等离子消融术组(58.9%),而 PEAK 等离子刀组仅为 17.8%,电灼组为 23%。
零假设被拒绝。即 PEAK 等离子刀安全有效,术后出血和急诊就诊次数在统计学上更少,尤其是与低温等离子消融术相比。低温等离子消融术组患者术后出血率最高。
