Post Intubation Sedation in Pregnant Patients

You have just intubated a seizing eclamptic woman who is 34 weeks pregnant. As she is being prepped for transfer to the OB unit for an emergent C-section your nurse asks you what medications you would like for post intubation analgesia and sedation.

You have limited recollection of whether Propofol crosses the placenta, and have legitimate concerns about Fentanyl’s chances of producing a ‘floppy baby’ for the OB team on delivery.

The literature on the most appropriate post intubation analgesia / sedation package for late pregnancy patients is limited. The agents we are the most familiar with in the emergency department for post intubation sedation and analgesia are Fentanyl and Propofol. One reliable mantra for post intubation analgesia and sedation is ‘Fentanyl is the sauce, and Propofol is the oregano’, it would be great to be able to apply this mantra to the pregnant population also.

Beyond ACLS: CPR, Defibrillation, and Epinephrine

Beyond ACLS - CPR, Defibrillation, & EpiAdvanced Cardiac Life Support (ACLS) provides a well structured framework for those who resuscitate infrequently. There is room to move beyond the algorithm to potentially provide better care for our patients for those who resuscitate frequently. I will describe some tweaks to the way CPR, defibrillation, and medications are delivered in the arrests I manage. Read more →

Skin Anesthesia: Lidocaine vs Bupivacaine +/- Epinephrine

Skin AnesthesiaWhen selecting a local anesthetic agent for skin wounds I have historically been taught to use lidocaine to provide a faster onset, and to use bupivacaine for a longer duration of action.

It can be time consuming to find 0.5% Bupivacaine with epinephrine and 2% Lidocaine with Epinephrine to produce a final mixture of 1% Lidocaine and 0.25% Bupivacaine with Epinephrine.

  • If there is no difference in effect between these agents time could be saved when drawing up local anesthetics.

Lidocaine + Bupivacaine vs Bupivacaine Alone for Digital Nerve Blocks

Digital Nerve BlocksWhen I first learned digital nerve blocks in the late 1990’s I was taught to mix Lidocaine and Bupivacaine 50/50 to provide faster onset (Lidocaine) and a longer duration of action (Bupivacaine). My use of two agents for digital nerve blocks was recently questioned by one of my colleagues.

Any time additional medications are drawn up into a syringe there is opportunity for error, and there is additional time added to the procedure. A review of the (limited) literature will try to answer the following questions:

  1. Does the addition of Lidocaine to Bupivacaine decrease the time to onset of anesthesia?
  2. Does the addition of Lidocaine to Bupivacaine decrease the pain of injection?
  3. Does the use of Lidocaine with Epinephrine prolong the duration of digital block long enough to obviate the need for Bupivacaine?
