Abstract
OBJECTIVE: To evaluate the correlation between pain intensity and comfort level in patients with pseudomyxoma peritoneum (PMP) before and after hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: From June 2018 to June 2019, patients who underwent HIPEC for PMP after surgical treatment in our institute were selected. The intra-abdominal pressure (IAP) and pain intensity (PI) before and after HIPEC were recorded, and the correlation between them was analyzed. RESULTS: Seventy-four patients received HIPEC 253 times. IAP and PI were significantly higher after perfusion than before perfusion (P < 0.05). When IAP < 12 cmH(2)O, the change of PI was not correlated to the increase of IAP, and the patient tolerated the treatment. However, when IAP > 12 cmH(2)O, the increase of PI was significantly associated with IAP and cause significant discomfort during the treatment. CONCLUSION: IAP may be a monitoring index for the comfort of PMP patients during the postoperative HIPEC treatment.
