The aim of this study was to evaluate a possible relationship between lunar cycles and haemorrhagic complication rate in surgery.
The possible relationship between moon phases and surgical outcome was tested by evaluating the haemorrhagic complication rate for 18,760 patients who underwent surgery between January 2001 and December 2008 at the National Institute for Cancer Research in Genoa. A total of 103 lunar phases were considered using Chi-square (χ) test analysis, and patients were allocated a surgery date.
One hundred and sixty-seven haemorrhagic complications were observed. Three hundred and nine new moon phase days were analysed and 12 incidences of complications detected, with a 3.9% complication rate per day. In the waxing moon phase, 1184.5 d were analysed with 68 incidences of complications at a daily rate of 5.7%. In the full moon phase there was a 4.9% complication rate per day (15 incidences in 309 d), whereas in the waning moon phase, the 6% percentage rate per day resulted from 72 incidences in 1184.5 d.
No statistically significant correlations were found between moon cycles and postoperative haemorrhagic complications (p = .50).
本研究旨在评估月周期与手术中出血并发症发生率之间的可能关系。
通过评估2001年1月至2008年12月在热那亚国家癌症研究所接受手术的18760例患者的出血并发症发生率，来检验月相与手术结果之间的可能关系。使用卡方（χ）检验分析共考虑了103个农历月相，并为患者分配了手术日期。
观察到167例出血并发症。分析了309个新月相日，检测到12例并发症，每日并发症发生率为3.9%。在盈月阶段，分析了1184.5天，有68例并发症，每日发生率为5.7%。在满月阶段，每日并发症发生率为4.9%（309天中有15例），而在亏月阶段，1184.5天中有72例，每日发生率为6%。
未发现月周期与术后出血并发症之间存在统计学上的显著相关性（p = 0.50）。
