The effect of physical restraint on neurovascular complications in intensive care units

Background: To reduce the neurovascular complications caused by physical restraint in intensive care patients, there is a need to examine the occurrence of neurovascular complications and their rate.

Objectives: The objective of this research was to investigate the effect of physical restraint on the occurrence of neurovascular complications and their rate.

Methods: A prospective observational cohort study was carried out. A total of 90 patients from anaesthesia and internal intensive care units participated in this study. Patients were assessed at intervals of 24 h for 4 days using the following instruments: Individual Characteristics Form, Richmond Agitation-Sedation Scale (RASS), Behavioral Pain Scale, and Complication Diagnostic Diary.

Results: Redness (p < 0.001), limb movement (p < 0.001), oedema (p < 0.001), and colour complication (p < 0.001) increased, whereas pulse strength (p < 0.001) decreased in physically restrained sites on the arm from day 1 to day 4. Redness was increased in patients physically restrained with all types of materials (p < 0.001; p < 0.001; p = 0.020). Although there was a statistically significant difference in terms of movement (p = 0.006; p = 0.003) and oedema (p < 0.001; p < 0.001), both with a roll of gauze and tough cuff, these complications were not significantly different in patients restrained with green foam tie (p > 0.05). According to logistic regression analysis, material type, position of the limb, space between the physical restraint and limb, age, RASS, and pain were independent risk factors for neurovascular complications. RASS and pain were independent protective factors against movement complications.

Conclusions: The duration of physical restraint increases neurovascular complications. This study revealed that nurses did not regularly check the restrained wrist and did not focus on the peripheral circulation. It is necessary to develop training programs, standards, and appropriate follow-up strategies in intensive care units in Turkey.
