Effect of pressure on pericardium 6 in nausea after cataract surgery in the elderly:A randomized clinical trial

Introdution: Cataract is a common surgery in older people. Nausea is an unpleasant feeling after general anesthesia that may cause serious effects on such patients. This article aimed to study the effect of pressure pericardium 6 on nausea after cataract surgery in elderly patients in the Khalili Hospital, Shiraz, Iran, in 1395. Methods: This randomized double-blind clinical trial was done on 50 elderly patients in the intervention group and 50 in the control group. An hour before the surgery, the patients closed a 30-band wristband containing a push-button at the point (P6), and in the control group, the same wristband was closed without a button. Five hours after the induction of general anesthesia, the wristband was removed from both groups and nausea level of the patients were recorded immediately after their recovery at 8 and 12 hours after the surgery. After 5 weeks, the data were collected and analyzed using SPSS version 16 and independent T-test (P-value < 0.05) . Results: The results showed the meaningful difference in average severity and frequency of nausea 8 hours after cataract surgery in two groups (p<0.01). But the severity of nausea immediately and 12 hours after cataract surgery was not significantly different in both groups (p>0.159). Conclusion: The finding showed that acupressure is effective in reducing the severity of nausea after cataract surgery. Due to low cost, low complication and simplicity of acupressure, it can be recommended as a way of caring by nurses and other medical staff in reducing nausea.
