The Effect of Patient-Controlled Analgesia Education for Patients with Laparoscopy-aided Gastrectomy

Postoperative pain management is an important nursing issue for patients’ comfort. In this context, this research aims to analyze the effect of patient- controlled analgesia education on patients’ satisfaction with pain management after operation. It is a nonequivalent control non-synchronized design. The subjects were among the patients who had laparoscopy-aided gastrectomy at a university medical center in Suwon from October 2012 to March 2013 and also met the research criteria. Eventually, experimental and control groups of 35 were selected respectively. The research measured the knowledge about pain and patient-controlled analgesia (PCA), level of pain, consumption of analgesics through PCA and satisfaction with pain management after education on PCA. SPSS/PC 19.0 program was applied for data analysis. General characteristics were calculated with real numbers and percentage, homogeneity of experimental group and control group was verified with chi-square test and t-test and hypothesis was tested with t-test. Following is the result. 1) Hypothesis 1. Pain knowledge of the experimental group who were educated on PCA before operation was 4.69±0.63 and that of the control group was 3.71±0.83. This means the former's pain knowledge was significantly higher than the latter's (t=-5.533, ρ=.049). Regarding the knowledge on PCA usage, the experimental group recorded 4.69±0.60 while the control group 3.66±0.94, also indicating the former knew PCA usage significantly better the latter (t=-11.024, ρ <.001). Therefore, hypothesis 1, which assumes that the experimental group would have better knowledge on pain and PCA usage after operation than the control group, is proved right with the result above. 2) Hypothesis 2. the experimental group who had PCA education before operation marked 4.11±0.47 of the pain level 24 hours after operation and the control group posted 4.85±0.91. This shows the former's pain level is significantly lower than the latter's (t= 4.281, ρ <.001). And 48 hours after operation, the former's pain level was 3.46±0.66 and the latter's was 4.03±0.66, resulting in significant reduction of pain level (t= 3.620, ρ= .001). Thus, hypothesis 2 is supported by the outcome. 3) Hypothesis 3. Analgesics consumption using PCA of the experimental group who were educated on PCA before operation was 57.00±4.72ml 24 hours after operation and that of the control group was 51.52±4.68ml. The former consumed significantly more than the latter (t= -4.833, ρ<.001). When 48 hours passed, the experimental group consumed 50.50±2.04ml, of analgesics by using PCA and the control group did 46.32±9.06ml, implying that the former consumed significantly more than the latter (t=-2.600, ρ=.011) and this supported hypothesis 3. 4) Hypothesis 4. Satisfaction with pain management was 49.14±1.24 for the experimental group offered with preoperative PCA education and 36.51±5.88 for the control group. The former showed significantly higher scores than the latter (t=-12.437, ρ< .001) to support hypothesis 4. To sum up, the PCA education performed for the patients with laparoscopy-aided subtotal gastrectomy helped lower the pain level they felt after operation by improving their knowledge on pain and PCA usage. The program also promoted satisfaction with pain management by consuming more analgesics through PCA. This verified that preoperative education on PCA including practice is an effective nursing intervention in pain management after operation, thus anticipated to be widely applied to the nursing field.
