Abstract：Objective To analyze the effect of improved head-low-foot-high lithotomy placement technique based on comfort care theory in lumpectomy for gynecologic malignancies. Methods One hundred patients with gynecological malignancies admitted to Ningbo Women’s and Children’s Hospital, Zhejiang Province from October 2019 to February 2020 were divided into two groups of 50 cases each using the random number table method. In the control group, the conventional head-low-hip-high lithotomy position was used intraoperatively, while the observation group used a modified head-low-foot-high lithotomy position technique based on comfort care theory. The fluctuations of arterial pressure lthe time points of detection were T1 to T3, i.e. after completion of anesthesia in the flat-lying truncal position [T1], 5 min after pneumoperitoneum with head low, and hip high position [T2], and 30 min after pneumoperitoneum with head low and hip high position [T3], position-related complications, and position comfort were observed. Results The difference in mean arterial pressure levels between the two groups was statistically significant (P＜0.05). The mean arterial pressure at T2 and T3 time points in the observation group was lower than that in the control group, and the difference was statistically significant (P＜0.05). At 24 h after surgery, the visual analogue scale(VAS) scores of numbness and pain in the shoulder，and lower limbs of the observation group were lower than those of the control group, and the differences were statistically significant (P＜0.05). At 48 h postoperatively, the VAS scores of numbness and pain in the shoulder，and lower limbs were lower in both groups than at 24 h postoperatively, and the differences were statistically significant (P＜0.05). At 48 h postoperatively, there were no statistically significant differences in the VAS scores of numbness and pain in the shoulder and lower limbs between the two groups (P＞0.05). The proportion of subcutaneous emphysema in the observation group was lower than that in the control group, while the postural comfort score was higher than that in the control group, with statistically significant differences (P＜0.05). Conclusion The improved head-low-foot-high lithotomy placement technique based on comfort care theory is used in laparoscopic surgery for gynecologic malignancies, and plays a good role in arterial pressure fluctuation relief, position-related prevention, and pain relief, which could effectively improve the comfort of patients’ position.
