Perioperative Medication Management for TMJ Joint Replacement Surgery

Preoperative Medication Management

Continue Gabapentin 300mg three times daily through the perioperative period for pain management, as part of a multimodal pain management strategy, in patients undergoing TMJ joint replacement and jaw surgery, to maintain pain control and provide opioid-sparing effects 1
Hold Diazepam for at least 12 hours before surgery to minimize the risk of psychomotor and cognitive impairment, hypotension, profound sedation, and respiratory depression when combined with anesthetics, in patients undergoing TMJ joint replacement and jaw surgery 1, 2
Continue acetaminophen (Tylenol) up to the day of surgery as part of multimodal analgesia, in patients undergoing TMJ joint replacement and jaw surgery, to maintain pain control and minimize the risk of bleeding and other complications 1

Continue Gabapentin 300mg three times daily postoperatively for pain management, as part of a multimodal pain management strategy, in patients undergoing TMJ joint replacement and jaw surgery, to maintain pain control and provide opioid-sparing effects 1
Resume Diazepam postoperatively only if specifically needed for jaw mobility, starting 24 hours after surgery, and consider tapering and discontinuing within 5-7 days after surgery if possible, to minimize the risk of psychomotor and cognitive impairment, hypotension, profound sedation, and respiratory depression when combined with anesthetics, in patients undergoing TMJ joint replacement and jaw surgery 1, 2
Resume acetaminophen (Tylenol) postoperatively as part of multimodal pain management, in patients undergoing TMJ joint replacement and jaw surgery, to maintain pain control and minimize the risk of bleeding and other complications 1

The American Geriatrics Society recommends avoiding benzodiazepines in older patients when possible, due to the risk of psychomotor and cognitive impairment, hypotension, profound sedation, and respiratory depression when combined with anesthetics, in patients undergoing TMJ joint replacement and jaw surgery 2
Combining benzodiazepines with anesthetics may cause hypotension, profound sedation, and respiratory depression, in patients undergoing TMJ joint replacement and jaw surgery, highlighting the need for careful medication management and monitoring 1
The World Health Organization recommends using multimodal analgesia with acetaminophen and NSAIDs, and considering gabapentin for patients undergoing procedures with high risk of acute pain or chronic postoperative pain 3, 2
Local anesthetic infiltration at the surgical site and regional anesthesia techniques are recommended as alternatives for post-operative orthopedic pain management, with dexamethasone 8 mg IV at induction supported by 4, 5
The Anaesthesia guidelines suggest considering low-dose ketamine (0.5 mg/kg/h) for surgeries with high risk of acute pain, as an evidence-based alternative for post-operative orthopedic pain management 4

Taper opioids as pain decreases, and taper and discontinue Diazepam if possible within 5-7 days, to minimize the risk of dependence, withdrawal symptoms, and other complications, in patients undergoing TMJ joint replacement and jaw surgery 1, 2
Consider discontinuing Gabapentin if no evidence of neuropathic pain by 4-6 weeks post-surgery, to minimize the risk of unnecessary medication use and potential side effects, in patients undergoing TMJ joint replacement and jaw surgery 1
The maximum duration of gabapentin use post-operatively should be 5-7 days, with tapering off as pain decreases, starting before other analgesics when pain decreases (reverse analgesic ladder) 6
Gabapentin should be tapered if no longer indicated after the immediate post-operative period, with daily assessment of pain scores and sedation levels, and reduction of dose if excessive sedation occurs 6

Gabapentin should be used as part of multimodal analgesia for post-operative neuropathic pain management, starting at 100-300 mg three times daily and titrating up to a maximum of 3600 mg/day in divided doses over 3-8 weeks, with an adequate trial requiring at least 2 weeks at the maximum tolerated dose, as recommended by the Mayo Clinic Proceedings and the American College of Physicians 7
Increase by 100-300 mg every 1-7 days as tolerated, with a maximum dose of 3600 mg/day in 3 divided doses, as suggested by the Mayo Clinic Proceedings 7
The American College of Surgeons recommends gabapentinoids as part of multimodal analgesia, but with limited use to a single lowest preoperative dose to avoid sedative side effects, as it reduces postoperative pain and opioid consumption, although benefits are offset by increased sedation, dizziness, and visual disturbances 2
The dose should be reduced to 100-200 mg for elderly patients (>65 years) due to increased sensitivity, and adjustments made for renal impairment based on creatinine clearance (CrCl) levels 2
Gabapentin should be combined with other non-opioid analgesics (such as paracetamol, NSAIDs) as part of multimodal analgesia, with monitoring for side effects, particularly sedation, dizziness, and visual disturbances 2, 8

Patients should be monitored for excessive sedation, dizziness, and respiratory depression, especially when combined with opioids, as suggested by the American Society of Anesthesiologists 9
Risk factors for increased side effects include advanced age, renal impairment, and concomitant CNS depressants, according to the American Geriatrics Society 9
Common side effects of gabapentin include sedation, dizziness, and visual disturbances, as reported by the American Society of Anesthesiologists 5, 2
Patients with vulnerability to pain, particularly those taking long-term opioids, require special consideration, as suggested by the American Pain Society 3
