Clinical Trial Summary

Evaluation of neuropsychiatric and cardiovascular side effects of low dose ketamine analgesic infusion for postoperative pain


Description:

Postoperative pain is a world wide problem related with surgery. Multimodal analgesia may include ketamine, aimed to decrease opioid adverse effects in postoperative analgesia for major surgery, and risk of chronic postsurgical pain. Ketamine has shown efficacy as adjuvant in multimodal analgesia, however, neuropsychiatric and cardiovascular effects of ketamine at low doses in continue postoperative infusion are less known. This type of adverse effects may compromise appropriated recovery.

Objective

to determine frequency of delirium, agitation, sedation, hallucinations, bad dreams and cardiovascular changes associated with ketamine analgesic infusion treatment for postoperative pain.

Outcome

Type Measure Description Time frame Safety issue
Other Hallucinations Presence or absence of hallucinations 24 and 48 hours postoperatively
Other Bad Dreams Presence or absence of bad dreams 24 and 48 hours postoperatively
Other Hypertension Hypertension is defined as a systolic blood pressure (SBP) of 140 mm Hg or more 0, 24 and 48 hours postoperatively
Other Tachycardia a heart rate of more than 100 beats per minute (BPM) 0, 24 and 48 hours postoperatively
Primary Delirium Presence or absence of delirium at 24 and 48 hours postoperatively over the past 2 days of exposure to ketamine infusion, using the Confusion Assessment Method (CAM), a clinical based assessment tool for identifying delirium. Consist of 4 criteria ( timing of symptoms, attention, thinking, consciousness). Considered to be positive for delirium if both features 1 and 2 are present, with at least one of features 3 or 4. 2 days
Secondary Agitation Richmond Agitation- Sedation Scale (RASS) score is a 10 point scale with discrete criteria, with four levels of agitation (+1 to +4), one level for calm and alert state (0), and 5 levels of sedation (-1 to -5) 24 and 48 hours postoperatively
Secondary Sedation Clinician based Richmond Agitation- Sedation Scale (RASS) at 24 and 48 hours. RASS is a 10 point scale with discrete criteria, with four levels of agitation (+1 to +4), one level for calm and alert state (0), and 5 levels of sedation (-1 to -5) 24 and 48 hours postoperatively
