acetaminophen and Obesity, Morbid

acetaminophen has been researched along with Obesity, Morbid in 16 studies

Acetaminophen: Analgesic antipyretic derivative of acetanilide. It has weak anti-inflammatory properties and is used as a common analgesic, but may cause liver, blood cell, and kidney damage.
paracetamol : A member of the class of phenols that is 4-aminophenol in which one of the hydrogens attached to the amino group has been replaced by an acetyl group.

Obesity, Morbid: The condition of weighing two, three, or more times the ideal weight, so called because it is associated with many serious and life-threatening disorders. In the BODY MASS INDEX, morbid obesity is defined as having a BMI greater than 40.0 kg/m2.

Trial Outcomes

Intensive Care Delirium Screening Checklist (ICDSC)

Number of patients who score greater than a 4 on the 0-8 point ICDSC scale to assess delirium scores. 8 separate levels of signs for delirium assessed (1. altered level of consciousness, 2. inattention, 3. disorientation, 4. hallucination, delusion, or psychosis, 5. psychomotor agitation or retardation, 6. inappropriate speech or mood, 7. sleep-wake cycle disturbance, 8. symptom fluctuation), with 0 points awarded when patient does not exhibit above signs of delirium and 1 point awarded per confirmed sign of delirium. Score then totaled, 0 = normal, 1-3 = subsyndromal delirium, 4-8 = delirium. (NCT03198871)
Timeframe: The delirium scores will first be measured every 12 hours for 72 hours after surgery.

SF-12 Health Survey

Survey to assess patient's overall health (via a combination of mental and physical health assessment) at 30 days post-discharge. Two summary scores are reported from the SF-12 - a mental component score (MCS-12) and a physical component score (PCS-12). The scores may be reported as Z-scores (difference compared to the population average, measured in standard deviations). The United States population average PCS-12 and MCS-12 are both 50 points. The United States population standard deviation is 10 points. So each 10 increment of 10 points above or below 50, corresponds to one standard deviation away from the average (NCT03198871)
Timeframe: These measurements will take place at 30-days post hospital discharge
