THE RELATIONSHIP BETWEEN POST OPERATIVE NAUSEA & VOMITTING (PONV) WITH TYPE OF EYE SURGERY WITH GENERAL ANESTHESIA

PONV is still the most common complaint by patients after undergoing surgery with general anesthesia. PONV is not well understood and its treatment cannot be carried out completely yet. However, in recent years, it has been known a number of risk factors that lead to PONV. Causes of PONV are multifactorial and classified as patient factors, surgery factors and pharmacological factor. In terms of surgery factors, eye surgery is one of the surgeries with a high level of incidence of PONV with differences in incidence of each type of eye surgery. This study was conducted to determine the relationship between the prevalence of post operative nausea and vomiting (PONV) and the type of eye surgery with general anesthesia in patients at SMEC Eye Hospital Medan. The type of this research is cross-sectional study. The study was conducted by using primary data from interview and patient's medical records from July 2014 to November 2014. The study included 53 subjects, consisting of a variety of patients with different types of surgery, both intraocular and extraocular. The results shows that 5 people (9.4%) were diagnosed with PONV, with complaints of nausea as the overall PONV. Onset of PONV experienced in the first 8 hours by 4 people (80%) and 1 person (20%) for the second 8 hours. Type of surgery with the highest incidence of PONV is intraocular surgery. This incidence suffered by 4 people (80%), with vitrectomy as the most diagnosed as many as 2 people (40%). The results of the chi-square statistical analysis found no significant correlation with p-value 0.199 (p > 0.05). Based on the analysis it can be concluded that there is no relationship between the prevalence of PONV with the type of eye surgery with general anesthesia. Suggested for subsequent researchers to conduct similar studies with wider coverage and planned a better distribution of the sample size.
