Patient/Parent Education Regarding
Pain Management
Pain Management
The intraoperative anesthesiologist explained to the family that a fascial plane block would be employed as a component of a comprehensive multimodal pain management plan.
Needle Size, Number of Syringes
2-inch 22-gauge echogenic needle from B. Braun used with 10 mL syringes (2) of local anesthetic injectate
Indicate Any Relevant Prep Instructions
After regional time out was conducted in the operating room prior to fascial plane blockade, the inguinal and infraumbilical abdominal wall were prepped with chlorhexidine solution.
The recommended dose of EXPAREL for infiltration in adults is based on the size of the surgical site, the volume required to cover the area, and individual patient factors that may impact the safety of an amide local anesthetic. The maximum dose of EXPAREL should not exceed 266 mg. The recommended dose of EXPAREL for patients aged 6 to <17 years old is 4 mg/kg, up to a maximum of 266 mg. The recommended dose of EXPAREL in adults for interscalene brachial plexus nerve block, sciatic nerve block in the popliteal fossa, and adductor canal is 133 mg. The recommended dose of EXPAREL in adults for adductor canal block is 133 mg (10 mL) admixed with 50 mg (10 mL) of 0.5% bupivacaine HCl, for a total volume of 20 mL.
EXPAREL can be administered unexpanded (20 mL) or expanded to increase volume up to a total of 300 mL (final concentration of 0.89 mg/mL [ie, 1:14 dilution by volume]) with normal (0.9%) saline or lactated Ringer’s solution.
PROCEDURAL DETAILS
Admix or administer EXPAREL® (bupivacaine liposome injectable suspension) separately
EXPAREL admixed with 0.25% bupivacaine HCl*
Dosing and Administration
6.5 mL†of EXPAREL + 13.5 mL of 0.25% bupivacaine HCl = 20 mL of TOTAL injectate
10 mL of injectate used on each side block
Other Intraoperative Analgesics
IV dexmedetomidine 10 mcg
IV morphine 2 mg
IV ketorolac 10 mg
Bupivacaine HCl (which is approved for use in patients aged 12 and older) may be administered immediately before EXPAREL or admixed in the same syringe, as long as the ratio of the milligram dose of bupivacaine HCl to EXPAREL does not exceed 1:2. Admixing may impact the pharmacokinetic and/or physicochemical properties of EXPAREL, and this effect is concentration dependent. The toxic effects of these drugs are additive and their administration should be used with caution, including monitoring for neurological and cardiovascular effects related to local anesthetic systemic toxicity. Other than with bupivacaine, EXPAREL should not be admixed with other drugs prior to administration.
IV=intravenous.
*Bupivacaine HCl is indicated for patients 12 years and older. The approach to using Bupivacaine HCl for this patient and procedure represents the individual clinical judgment of Dr Patel.
†EXPAREL is available in 10 mL and 20 mL vials.
For this procedure, a standard ilioinguinal/iliohypogastric fascial plane block was performed using ultrasound. An HFL50 15-6 MHz probe was placed in the inguinal region in an orientation from the umbilicus to the anterior superior iliac spine.
In the sonographic view below, the II/IH nerves were visualized in the fascial plane between the transversus abdominis muscle and the interior oblique muscle. A 2-inch 22-gauge echogenic B. Braun needle was used to deposit 10 mL of the local anesthetic admixture. The same injection was repeated on the contralateral side with another 10 mL of the local anesthetic admixture.
POSTSURGICAL INSTRUCTIONS INCLUDING PRESCRIPTIONS PROVIDED AND RECOVERY MILESTONES AND GOALS
The patient’s family was informed that the blocks should provide significant postsurgical pain relief to the surgical area. In addition, the surgical team would be prescribing oral pain medication (acetaminophen and ibuprofen) to take up to every 6 hours prn for postsurgical pain relief.
PATIENT FOLLOW-UP
The patient recovered in the PACU uneventfully, reporting an NRS pain score of 0 and stating she had complete numbness of her groin. No additional medications were administered in the PACU and she was discharged home in the care of her parents within 38 minutes of arrival from the operating room.
A phone call to the family the following day confirmed that the sensory blockade to the patient’s inguinal region lasted 24 hours. Both patient and family were satisfied with the fascial plane blockade. Patient recovery was opioid-free.

Important Notice
- This site is intended to provide medical and product information to health care professionals in the United States.
- To report an adverse event, email drugsafety@pacira.com or call 1-855-793-9727.
- For medical inquiries related to EXPAREL, submit a request to Medical Information or call 1-855-793-9727.
- These are not all of the potential important safety considerations for EXPAREL; please see the full Prescribing Information.
Indication
EXPAREL® (bupivacaine liposome injectable suspension) is indicated to produce postsurgical local analgesia via infiltration in patients aged 6 years and older and regional analgesia in adults via an interscalene brachial plexus nerve block, sciatic nerve block in the popliteal fossa, and an adductor canal block. Safety and efficacy have not been established in other nerve blocks.
Important Safety Information
- EXPAREL is contraindicated in obstetrical paracervical block anesthesia.
- Adverse reactions reported in adults with an incidence greater than or equal to 10% following EXPAREL administration via infiltration were nausea, constipation, and vomiting; adverse reactions reported in adults with an incidence greater than or equal to 10% following EXPAREL administration via nerve block were nausea, pyrexia, headache, and constipation.
- Adverse reactions with an incidence greater than or equal to 10% following EXPAREL administration via infiltration in pediatric patients six to less than 17 years of age were nausea, vomiting, constipation, hypotension, anemia, muscle twitching, vision blurred, pruritus, and tachycardia.
- Do not admix lidocaine or other non-bupivacaine local anesthetics with EXPAREL. EXPAREL may be administered at least 20 minutes or more following local administration of lidocaine.
- EXPAREL is not recommended to be used in the following patient populations: patients <6 years old for infiltration, patients younger than 18 years old for nerve blocks, and/or pregnant patients.
- Because amide-type local anesthetics, such as bupivacaine, are metabolized by the liver, EXPAREL should be used cautiously in patients with hepatic disease.
Warnings and Precautions Specific to EXPAREL
- Avoid additional use of local anesthetics within 96 hours following administration of EXPAREL.
- EXPAREL is not recommended for the following types or routes of administration: epidural, intrathecal, regional nerve blocks other than interscalene brachial plexus nerve block, sciatic nerve block in the popliteal fossa, and adductor canal block, or intravascular or intra-articular use.
- The potential sensory and/or motor loss with EXPAREL is temporary and varies in degree and duration depending on the site of injection and dosage administered and may last for up to 5 days, as seen in clinical trials.
Warnings and Precautions for Bupivacaine-Containing Products
- Central Nervous System (CNS) Reactions: There have been reports of adverse neurologic reactions with the use of local anesthetics. These include persistent anesthesia and paresthesia. CNS reactions are characterized by excitation and/or depression.
- Cardiovascular System Reactions: Toxic blood concentrations depress cardiac conductivity and excitability, which may lead to dysrhythmias, sometimes leading to death.
- Allergic Reactions: Allergic-type reactions (eg, anaphylaxis and angioedema) are rare and may occur as a result of hypersensitivity to the local anesthetic or to other formulation ingredients.
- Chondrolysis: There have been reports of chondrolysis (mostly in the shoulder joint) following intra-articular infusion of local anesthetics, which is an unapproved use.
- Methemoglobinemia: Cases of methemoglobinemia have been reported with local anesthetic use.
