Clinical Trial Summary

The purpose of this prospective observational study is to investigate the changes in sleep architecture after a hip surgery and its potential association with postoperative delirium and postoperative cognitive dysfunctions respectively.


Description:

Sleep research has confirmed the association of sleep (REM sleep and slow-wave sleep) with memory and cognitive function in general. There are changes in the quantity of REM sleep after certain forms of anesthesia, especially with barbiturate, as shown in mouse model. This study is designed to be the first explorative clinical studyl to measure changes in sleep architecture in surgical patients undergoing different types of anesthesia (general anesthesia and spinal anesthesia) and its potential associations with the development of postoperative delirium and postoperative cognitive dysfunction. Additionally, parameters will be collected, that from recent research are suspected to be reliable markers for systemic inflammation that might account for delirium and cognitive dysfunction after surgical interventions.

Patients were stratified into two groups: age (≤ 65 years; > 65 years) and benzodiazepine premedication (yes/no).

Outcome

Type Measure Description Time frame Safety issue
Other Tissue Inhibitor of Metalloproteinases Metalloproteinases (MMP-2 und MMP-9) from liquor samples (only in patients with spinal anesthesia). At time of spinal anesthesia
Other Metalloproteinases Metalloproteinases (MMP-2 und MMP-9) from liquor samples (only in patients with spinal anesthesia). At time of spinal anesthesia
Other ASA (physical status classification system) status At the beginning of the investigation
Other Benzodiazepine premedication At the beginning of the investigation
Primary Changes in prevalence of rapid eye movement sleep Changes in prevalence of rapid eye movement (REM) sleep in the preoperative night compared to the night following the first postoperative day, including potentially compensatory sleep during daytime after surgery.
Sleep architecture will be measured with the Somnoscreen device for mobile polysomnography for a total time duration of 36 h (beginning in the preoperative evening, to be finished the morning of the second postoperative day).
Up to 36 hours
Secondary Insomnia Severity Index The ISI will be assessed by self-assessment questionnaire Up to 90 days after the operation
Secondary Malnutrition Malnutrition Screening Tools Up to 90 days after the operation
Secondary Epsworth Sleepiness Scale The ESS will be assessed by self-assessment questionnaire Up to 90 days after the operation
Secondary Postoperative Cognitive Dysfunction Postoperative Cognitive Dysfunction will be measured at hospital discharge and at the 90th postoperative day. Up to 90 days after the operation
Secondary Depth of anesthesia Depth of anesthesia will be measured by processive Electroencephalography and Electromyography (EEG/EMG) -Data (SedLine®) At time of surgery
Secondary Opioid requirements Postoperative pain will be measured by Numeric Rating Scale - Visualized (NRS-V), the Faces Pain Scale - Revised (FPS-R), the Behavioral Pain Scale (BPS) or the Behavioral Pain Scale for Non-Intubated (BPS-NI) Participants will be followed up for hospital stay an expected average of 7 days
Secondary Length of hospital stay Participants will be followed up for hospital stay an expected average of 7 days
Secondary Pain Postoperative pain will be measured by Numeric Rating Scale - Visualized (NRS-V), the Faces Pain Scale - Revised (FPS-R), the Behavioral Pain Scale (BPS) or the Behavioral Pain Scale for Non-Intubated (BPS-NI) Participants will be followed up for hospital stay an expected average of 7 days
Secondary N-Methyl-D-aspartate (NMDA)-receptor autologous antibodies Identification of NMDA-receptor autologous antibodies in blood serum and cerebrospinal fluid; the requested blood samples will be collected on the operation day, on the last day of hospitalisation and after 90 days. The requested liquor samples will be collected on the operation day (only in patients with spinal anesthesia). Up to 90 days after the operation
Secondary Inflammation parameters Assessment of inflammation parameters by means of extended differential blood count (Sysmex) ; the requested blood samples will be collected on the preoperative day, on the day of the intervention, on the following day and on the last day of the hospitalisation Participants will be followed up for hospital stay an expected average of 7 days
Secondary Hemodynamic parameters Hemodynamic variables are assessed by the anesthesia monitor and esophageal Doppler Monitor At time of surgery
Secondary Changes in prevalence of rapid eye movement sleep REM-Sleep at operation day/night in comparison to preoperative night. Sleep architecture will be measured with the Somnoscreen device for mobile polysomnography for a total time duration of 24 h. Up to 24 hours
Secondary Changes in prevalence of slow-wave sleep (Stadium 3 of non rapid eye movement-sleep) Slow wave sleep at operation day/night in comparison to preoperative night. Sleep architecture will be measured with the Somnoscreen device for mobile polysomnography for a total time duration of 24 h. Up to 24 hours
Secondary Changes in prevalence of slow-wave sleep (Stadium 3 of non rapid eye movement-sleep) Changes in prevalence of slow-wave sleep in the preoperative night compared to the night following the first postoperative day, including potentially compensatory sleep during daytime after surgery.
Sleep architecture will be measured with the Somnoscreen device for mobile polysomnography for a total time duration of 36 h (beginning in the preoperative evening, to be finished the morning of the second postoperative day).
Up to 36 hours
Secondary Postoperative complications Including Severity of Delirium Participants will be followed up for hospital stay an expected average of 7 days
Secondary Transfusion requirements Participants will be followed up for hospital stay an expected average of 7 days
Secondary Catecholamine administration intra- und postoperative Participants will be followed up for hospital stay an expected average of 7 days
Secondary Severity of postoperative Delirium Delirium screening will be conducted preoperatively, one hour postoperative, the evening of operation day, and the following morning with the scoring devices of confusion assessment method (CAM), by confusion assessment method in the intensive care unit (CAM-ICU) or by Nursing Delirium Screening Scale (Nu-DESC) Up to 36 hours
