Nociception Monitoring in Intensive Care

Pressure Ulcer Clinical Trial

Official title: Nociception Level Index Guidance for Analgesia in Pressure Ulcer Care in Unconscious Patients: A Pilot Study

Status Completed

Clinical Trial Summary

Precisely, pain in the ICU is a multidimensional problem with a multivariate of reasons. Still, it would be simpler to manage it in unconscious palliative patients with less source of pain, but only if we can detect it practically with the help of nociception monitors. Using five parameters, nociception level index (NOL) monitoring (Medasense) is differentiated from its alternatives. Other than pain detection, this monitoring can titrate analgesic administration. This study investigates the validity of a new nociception monitoring tool, the nociception level index, and its practical impact on providing adequate analgesia in palliative patients in intensive care.

Clinical Trial Description

The study design is randomized, prospective, and controlled in the setting of a level two intensive care unit. 40 patients (n=20) were randomized into control and nociception level. During daily pressure ulcer care, the nociception group received analgesia according to nociception level index monitorization, and the control group had the same protocol as fentanyl bolus doses of 1mcq/kg due to critical care observation pain tool assessment scores. Secondarily, hemodynamic values and variability were evaluated. Randomization was designed by a computer-based algorithm in a 1:1 ratio into 2 (n= 20) named Group NOL and Group Control and sealed into opaque envelopes. When the inclusion/exclusion criteria are met, at the scheduled time of wound care, the caregiver nurse in the ICU chooses one envelope to apply the designed protocol for each group. Study Intervention Caregiver nurses in the ICU were educated by the responsible doctor (B.C.) regarding the procedures after selecting study groups. In our ICU unit, routine patient care and simultaneous pressure ulcer interventions are done twice daily as day and night sessions. In our study, the caregiver nurse observed hemodynamic variables and CPOT values for pain evaluation 30 minutes before the day session of care and administered tramadol 1 mg/kg routinely. If CPOT values were still high, then one mcq/kg bolus of fentanyl at each time would be applied and repeated at five-minute intervals, if necessary, during care and 30 minutes after. Hemodynamic variables and CPOT values were noted as before, during, and after care for all patients within two groups, along with stages of pressure ulcers, and all patients had standardized care procedures. Notably, in Group NOL patients, the caregiver nurse assessed pain by NOL monitorization along with CPOT and hemodynamic variables and applied the same analgesia protocol by deciding analgesic need if NOL >25 over one minute at the monitor. Primary outcome The total amount of analgesia for every patient was noted as the total amount of analgesic drugs used to be stated separately as tramadol and fentanyl within the period starting from 30 minutes before until 30 minutes aftercare. Although the total amount of tramadol used was in standardized protocols as 1 mg /kg, it was also investigated to refrain misevaluation due to overtreatment. Secondary outcome Heart rate and blood pressure changes before and after care were evaluated within groups, and delta values calculated as the difference between the values at the beginning of ulcer care and before were also noted to question the effect of NOL monitorization on hemodynamic stability. ;
