Transdermal fentanyl as an adjuvant to paravertebral block for pain control after breast cancer surgery: A randomized, double-blind controlled trial

Transdermal Fentanyl Patch Effectiveness in Postoperative PainManagement in Orthopedic Patients: Literature Review

Controlling pain after major orthopedic surgery may be challenging, and it is related to delayed recovery, the development of chronic pain, and analgesic dependence. It is well known that effective postoperative pain control can reduce hospital stays by ensuring a more rapid rehabilitation,thereby decreasing the overall costs. Despite the development of analgesics, the use of opioids and their derivates remains the cornerstone of treatment for patients with acute moderate-to-severe pain in association with general or regional anesthesia. To reduce the risk of side effects and opioid addiction, considering the alarming epidemiological reports in relation to opioid abuse, combined analgesic methods are used, in addition to lower dosages or different forms of administration, such as transdermal administration. Fentanyl transdermal patches appear to be effective in controlling postoperative pain as part of multimodal analgesic regimens in knee and hip surgery, shoulder arthroplasty, traumatic fractures, and one-day surgery; this treatment has fewer associated side effects and can be safely used even in patients with renal impairment. It is also recommended for postoperative pain management in combination with a femoral-sciatic nerve block during foot and ankle surgery.

Comparaison of Efficacy and Safety of Fentanyl Transdermal Patch with Oral Ketorolac for Pain Management in Dry Socket: A Randomized Clinical Trial

Objectives

The aim of this study was to compare the efficacy and safety of transdermal Fentanyl patch with oral Ketorolac for pain management in dry socket patients.

Study design

Sixty patients who were diagnosed with dry socket (VAS > 40 mm) were recruited in this prospective randomized controlled trial. Patients were divided into two groups. Group1 (n = 30) Transdermal Fentanyl patch (25mcg/hr) was given and in Group 2 (n = 30) Ketorolac 10 mg Oral tablet was prescribed for pain management. The primary endpoint was the mean pain scores within 72 h evaluated by visual analog scale (VAS). Secondary measures included the safety and tolerability, amount of rescue medication (analgesic and antiemetic) and effectiveness of treatment interventions by Brief Pain Inventory Questionnaire (BPI).

Results

The mean VAS pain scores were significantly less in group 1 (Fentanyl) as compared to group 2 (ketorolac) on all follow-up days. Significant difference was noted in the mean amount of rescue analgesic medication. It was 2.16 + 1.53 in group 1 and 8.50 + 3.98 in group 2. Side effects were seen in both the groups. Nausea (46%) and vomiting (43%) were reported in group 1 while headache (36.6%) and epigastric pain (53.3%) in group 2.

Conclusions

Thus, transdermal Fentanyl was better in pain control than Ketorolac with less need for rescue analgesic medication in dry socket.

Consensus Perioperative Management Best Practices for Patients on Transdermal Fentanyl Patches Undergoing Surgery

PURPOSE OF REVIEW

The administration of a transdermal fentanyl patch can be complicated with different pharmacokinetics than other fentanyl preparations.

RECENT FINDINGS

The medical condition and baseline opioid requirements must all be carefully considered when dosing a fentanyl patch. An advantage of the fentanyl patch is its ability to bypass the gastrointestinal tract and in many patients, provide effective analgesia with minimal side effects. Fentanyl patches must be carefully administered since morbidity and/or mortality can result from the following: Giving higher doses than a patient needs, combining the medication with potent sedatives, or heating a fentanyl patch. The use of a transdermal fentanyl patch for the treatment of acute postoperative pain is not recommended and any patient undergoing a surgical procedure should have the fentanyl patch removed preoperatively. The current manuscript discusses the history of fentanyl and the fentanyl patch, as well as perioperative considerations, contraindications, current clinical efficacy, and clinical adversities related to the transdermal fentanyl patch. Regarding the heating of a transdermal fentanyl patch, which significantly increases blood levels of fentanyl, it is of the utmost importance that the patch be removed prior to surgery.
