Preventive effect of memory foam position pads on intraoperative pressure-induced skin injuries in gynecological malignancy patients undergoing lithotomy positioning.

This study explores the effect of memory sponge body position pad on pressure injury of compressed skin in patients undergoing lithotomy. From October 2021 to March 2022, 94 adult patients with gynecological malignancies who underwent elective general anesthesia surgery in our hospital and were in the lithotomy position during the operation were selected as the research objects. According to the different kinds of nursing, they were divided into 47 cases in the control group and 47 cases in the experimental group. The control group used silicone gel pads, and the experimental group used memory sponge pads. The incidence of pressure injury (PI), postoperative comfort contact area and average pressure of pressure part, and the surface microenvironment of the pressure part were compared between the 2 groups. Compared with the control group (17.02%), the incidence of PI in the observation group (2.13%) was significantly lower (P < .05); Compared with the control group (12.77%, 17.02%, 21.28%), the incidence of limb numbness (0.00%), waist muscle pain (4.26%) and neck and shoulder pain (6.38%) in the observation group were significantly lower (P < .05); Compared with the control group, the contact area of the compressed part in the observation group increased significantly and the average pressure decreased significantly after anesthesia, after positioning, during and after operation (P < .05); Compared with the pressure for 1 hour, the humidity and temperature of the feet, buttocks, and shoulders of the 2 groups were significantly higher after 2 hours of pressure, while the humidity and temperature of the feet, buttocks, and shoulders were significantly lower in the observation group compared to the control group (P < .05). The memory sponge position pad can prevent the occurrence of PI on the compressed skin of patients undergoing lithotomy and can also improve the postoperative comfort of patients and the surface microenvironment of the compressed part, which has high clinical reference value.
