[DEVELOPMENT AND CLINICAL APPLICATION OF MEDICAL HEAT PRESERVATION DEVICE USED IN HAND SURGERY].

OBJECTIVE

To introduce a new medical heat preservation device, and to explore the application value and effectiveness in replantation of severed fingers.

METHODS

The medical heat preservation device was design, water was used as the heating medium, and temperature was set and controlled by microcomputer. Between November 2010 and January 2014, 421 cases undergoing replantation of severed fingers were divided into 2 groups. Within 9 days after operation, the medical heat preservation device was used in 210 cases (experimental group), and the conventional heat lamp was used in 211 cases (control group). There was no significant difference in gender, age, injury cause, the interval between injury and admission, injury finger side, and operation time between 2 groups (P > 0.05). The vascular crisis rate, success rate of replantation of severed fingers, comfort, sleep quality, and the influence on roommates were compared.

RESULTS

The comfort and the influence on roommates were good in 188 cases (89.52%) and 201 cases (95.71%) in the experimental group, which were significantly higher than those in the control group (25/211, 11.85%; 145/211, 68.72%). According to Pittsburgh sleep quality index (PSQI) for sleep quality, the results were good in 105 cases, fair in 85 cases, and poor in 20 cases in the experimental group; the results were good in 45 cases, fair in 95 cases, and poor in 71 cases in the control group. Blood vessel crisis occurred in 35 cases (16.67%) of the experimental group, which was significantly lower than that in the control group (76/211, 36.02%) (P < 0.05). The survival rate of replantation in the experimental group (196/210, 93.3%) was significantly higher than that in the control group (181/211, 85.78%) (P < 0.05). Significant differences were found between 2 groups (P < 0.05) in above indexs.

CONCLUSION

Medical heat preservation device for replantation of severed fingers can improve the comfortable degree of patients and the quality of sleep, increase the survival rate of finger replantation, and reduce the occurrence of vascular crisis after operation.
