Bupivacaine

Intravascular Injection Risk (0.75% strength caution); Risk of Cardiac Arrest with Use in Obstetrical Anesthesia

Intravascular Injection Risk

  • The 0.75% concentration of bupivacaine is not recommended for obstetrical anesthesia.
  • There have been reports of cardiac arrest with difficult resuscitation or death during use of bupivacaine for epidural anesthesia in obstetrical patients. In most cases, this had followed use of the 0.75% concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management. Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% concentration should be reserved for surgical procedure where a high degree of muscle relaxation and prolonged effect are necessary.

Risk of Cardiac Arrest with Use in Obstetrical Anesthesia

  • There have been reports of cardiac arrest with difficult resuscitation or death during use of Bupivacaine Hydrochloride Injection for epidural anesthesia in obstetrical patients. In most cases, this has followed use of the 0.75% (7.5 mg/mL) concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management. Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% (7.5 mg/mL) concentration of Bupivacaine Hydrochloride Injection is not recommended for obstetrical anesthesia and should be reserved for surgical procedures where a high degree of muscle relaxation and prolonged effect are necessary [see Warnings and Precautions (5.1)].

 

Bupivacaine Solution for Infiltration Use

Risk of Potential Adverse Embolic Effects

  • Inadvertent intravascular injection could cause POSIMIR droplets to be deposited in the pulmonary and other capillary beds. Administer POSIMIR into the subacromial space at the end of arthroscopic shoulder surgery. Direct arthroscopic visualization must be used to confirm proper placement of the needle tip before injecting POSIMIR
