Evaluation of Nursing Actions in Anesthesia Guided by the Patient Safety Checklist: Nursing in Anesthetic Procedure (PSC/NAP): A Cross-Sectional Study

Evaluation of different body temperature measurement methods for patients in the intraoperative period

OBJECTIVES

this study aimed at estimating and comparing the reliability of temperature measurements obtained using a peripheral infrared temporal thermometer, a central cutaneous thermometer ("Zero-Heat-Flux Cutaneous thermometer") and an esophageal or nasopharyngeal thermometer among elective surgical patients in the intraoperative period.

METHOD

a longitudinal study with repeated measures carried out by convenience sampling of 99 patients, aged at least 18 years old, undergoing elective abdominal cancer surgeries, with anesthesia lasting at least one hour, with each patient having their temperature measured by all three methods.

RESULTS

the intraclass correlation coefficient showed a low correlation between the measurements using the peripheral temporal thermometer and the central cutaneous (0.0324) and esophageal/nasopharyngeal (-0.138) thermometers. There was a high correlation (0.744) between the central thermometers evaluated.

CONCLUSION

the data from the current study do not recommend using infrared temporal thermometers as a strategy for measuring the body temperature of patients undergoing anesthetic-surgical procedures. Central cutaneous thermometers and esophageal/nasopharyngeal thermometers are equivalent for detecting intraoperative hypothermia.

Different Concentrations of Ropivacaine under Ultrasound Guidance on Quadratus Lumbar Muscle Nerve Block in Elderly Patients with Hip Replacement

Objective

To compare the effect of ropivacaine in different concentrations under ultrasound guidance on lumbar muscle nerve blocking in elderly patients undergoing hip replacement surgery.

Methods

60 elderly patients underwent hip replacement in our hospital over a period of April to December of 2019 were equally randomized into control and observation groups, with 30 each. Patients in the control group and observation group received 0.5% and 0.25% ropivacaine to block psoas muscle nerve, respectively. The anesthetic effect of ropivacaine at different concentrations was evaluated by time of sensory block onset and recovery and time of motor block onset and regression, blood pressure, heart rate, visual analogy scale, and postoperative nerve blocking degree.

Results

The onset time of sensory and motor block in the observation group was dramatically higher than that in the control group (P < 0.05), while the recovery time of sensory and motor was significantly shorter than that of the control group (P < 0.05). The heart rate in the observation group was notably lower than that in the control group, while the average blood pressure was remarkably higher (P < 0.05). After surgery, the degree of nerve block in the observation group was much lower compared with the control group (P < 0.05), while no marked difference in the visual analogue scale in the control group before and after surgical intervention was observed (P > 0.05).

Conclusion

The 0.25% ropivacaine method has distinctive advantages over 0.50% ropivacaine psoas nerve anesthesia in hip replacement surgery in elderly patients.
