Descrizione dettagliata
The purpose of this project is to study the effects of preoperative followed by scheduled intravenous acetaminophen on pain control for 24 hours postoperatively after minimally invasive 1 or 2 level transforaminal lumbar interbody fusion. The advantages of intravenous acetaminophen are well known in the literature and its opioid-sparing effects have been documented in multiple surgical studies.
Multimodal regimens are now being advocated in the literature to decrease opioid use (8, 23). This is especially significant in spine surgery patients who often have chronic pain requiring long-term use of these habit-forming drugs as well as in patients who may not be able to tolerate opiods due to health status.
To our knowledge there are no studies done in the U.S. on the opioid sparing and pain reducing effects of intravenous acetaminophen on patients undergoing elective minimally invasive 1 or 2 level transforaminal lumbar interbody fusion. Investigating intravenous acetaminophen, particularly its pain reducing and opioid sparing effects, may give surgeons another medication for use in a multimodal approach to pain.

Misura Descrizione |
Lasso di tempo |
|---|---|---|

VAS
Lasso di tempo: Q4 x 24 hours averaged
|
The Visual Analogue Scale (VAS) and Verbal Rating Scale (VRS) will be measured at 4 hour intervals for a 24-hr period - measures of pain intensity in clinical and research settings.
0-10 Numeric pain intensity scale.
0 is no pain, 5 is moderate pain, and 10 is worst possible pain

Level of 100% Sedation
Lasso di tempo: 4-hr intervals for a 24-hr period averaged
|
Sedation will be measured on a scale of 1 to 5 at 4-hour intervals as follows: 1-completely awake; 2-awake but drowsy; 3 asleep, but responds to verbal commands; 4-asleep but responds to tactile stimuli; and 5-asleep and not responding to any stimuli.

4-hr intervals for a 24-hr period averaged

Vital Signs
Lasso di tempo: 4-hour intervals (+/- 30 minutes) for 24-hrs averaged
|
Routine postoperative vital signs will be collected at 4-hour intervals (+/- 30 minutes) postoperatively respiratory rate, oxygen saturation, mean arterial pressure, and heart rate.
Any reports of headache, dizziness, nausea, vomiting, pruritis, agitation, constipation, insomnia, bradycardia (Heart rate below 60 beats per minute), hypotension (MAP less than 30% of baseline), or urinary retention will be recorded throughout the study and will be treated appropriately as they occur, and the treatment medication will be stopped if determined to be a causative factor.
