Study of the Effect of Semi-upright Position on Nausea and Vomiting during Chemotherapy in Patients Referring to Omid Hospital in Mashad

The purpose of this quasi-experimental study is to determine the effect of semi-upright position on nausea and vomiting in the canceral patients , who were under chemotherapy in omid hospital of Mashad in 1999. The sample included 91 subjects who were selected purposely . They were studied in two days of chemotherapy period randomly , one day in semiupright and the second day in horizontal position . The parameters of N/V were compared during chemotherapy in two positions (for 4 hours) . Chemotherapy and antiemetic regimen in two days were similar . Demographic information and other data were collected about cancer , chemotherapy and vomiting by four point scale . Findings showed that incidence of nausea in semiupright and horizontal position were (48.4%) and (64.8%) respectively ; also means of nausea intensity were (11.2+ 4.5) and (21.19 + 7.9) ; means of nausea duration were (2.5 + 1.4) and (5.3 +.4) in the two positions respectively . Paired T-Test showed a significant difference between two positions in all cases . All characteristics of N/V semiupright , in comparison with horizontal position , decreased significantly but did not reach zero . So this safe and simple method is applicable in chemotherapic patients as completion of antiemetic drugs .
