A pillow or folded sheet was given to the patients for splinting purposes and DBandC was started for both groups. In each session, three cycles of three deep breaths were performed followed by an episode of coughing. The patient was asked to rate his/her pain from 0 to 10 on the NSR after completion of the third cycle. At the end of the fourth session, all patients were asked if they preferred the gel pack prior to DBandC. RESULTS The patients ranged in age from 22 to 75 years, and the average age was 58.3 �� 10.7 years in the group that began the trial with the gel pack and 60.7 �� 11.1 years in the group that began the trial without the gel pack. There were 50 patients (35 males and 15 females) recruited for this study from post cardiac surgery ICU, and no side effects or complications due to the cold therapy via gel pack were reported. All patients had one graft, and for all of them, saphenous vein was used. All patients had an admission diagnosis of CAD. Also, the results showed that there were no statistically significant differences in the variables such as age, gender, he moglobin level, the time between receiving analgesic and intervention, and body mass index (BMI) in the two groups at the beginning of study (P > 0.5). All patients received drugs for postoperative pain management as needed. Average pain scores between the group that started with the gel pack [mean (M) = 4.56, standard deviation (SD) = 1.64] and the group that started without the gel pack (M = 5.36, SD = 1.7) were not significantly different (t = ?1.7, df = 48, P = 0.1). A 2 (intervention) �� 2 (session) �� 2 (time) within-subjects repeated measures analysis of variance (R M-ANOVA) was conducted on the pain intensity scores before and after DB and C in patients undergoing open heart surgery by median sternotomy. The three independent variables were: intervention with two levels (gel pack and no gel pack application), session with two levels (a.m. and p.m.), and time with two levels (befor and after). The dependent variable was pain intensity. The M and SD values for the intensity scores are presented in Table 1. Pain scores after DB and C were, on average, 6.18/10 without gel pack compared to 3.81/10 with gel pack. The interaction between intervention and time was significant (P < 0.001) [Table 2] and indicated that the pain scores after DB and C were significantly lower when patients used the gel pack. The main effects with regard to intervention and session on pain were significant (P < 0.001) and with regard to time was non-signficant (P = 0.052).
