Objective To analyze the correlation between pressure ulcer during operation and operation time under lateral operation position.Methods 89 operation patients all adopted lateral position.Pressure ulcer during operation was observed and operation time was registered.Results The operations went on smoothly.Operation time lasted 1 to 8 hours.There were 42 operations exceeded 4 hours and pressure ulcer during operation was observed in 15 patients.Positive rate was 35.7％.There were 47 operations lasted less than 4 hours and pressure ulcer during operation was observed in 6 patients.Positive rate was 12.8％.Statistical differences were significant between the two groups.Conclusions For those operation patients with lateral position whose operation time would be longer,especially more than 4 hours,nursing intervention measures should be adopted to prevent pressure ulcer during operation.

Objective To explore the effect of risk management on the perioperative nursing of elderly patients undergoing cardiovascular surgery.
