80 something year old male came for reverse total shoulder replacement. He had severe COPD as well as an EF 20% with CHF. He had been appropriately optimized. Preoperatively, we performed an anterior approach suprascapular block (10ml, 0.25% bupi) combined with an infraclavicular block (20ml, 0.25% bupi). In retrospect, we could have used 5ml for suprascapular block and 15ml for infraclavicular block.
VATs: Dilute liposomal bupivacaine (266 mg, 20 cc) mixed with 20 cc injectable saline. We use two syringes to save time (refill syringe between injections).
For planned thoracotomy, we add 60 cc injectable saline for wider injection.
The efficacy of this strategy requires attention to specific details, such as timing and technique of injection, dilution with saline, and injection of multiple interspaces (typically interspaces 3–10 when technically possible).
Inject EXPAREL slowly and deeply (generally 1-2 mL per injection) into soft tissues using a moving needle technique (ie, inject while withdrawing the needle)
Infiltrate above and below the fascia and into the subcutaneous tissue
Aspirate frequently to minimize the risk of intravascular injection
Use a 25-gauge or larger-bore needle to maintain the structural integrity of the liposomal particles
Inject frequently in small areas (1-1.5 cm apart) to ensure overlapping analgesic coverage
20-something year old primip came today with preeclampsia and was deemed a c/s candidate for her 26 week baby. She was 5’8″, 165lb and had no prior issue with previous surgeries. She was started on magnesium preop. The mag was held intraoperatively and would resume postoperatively. Pt was in sitting position for her spinal, which was placed at L4-5. Good clear CSF return. 0.75% bupi dosed at 13.5 mg with intrathecal fentanyl 15mcg and intrathecal morphine 0.2mg. BP decreased from 150s to 130s, which was appropriate. Patient stated she had increased tingling and decreased mobility in her legs. All symptoms and signs appropriate with her spinal. Patient passed the Allis clamp test prior to incision. She was quite anxious: propofol was given IV for anxiolysis. Patient was adamant about breastfeeding/pumping for her baby. No complications with delivery. Uterus was externalized and patient was sensitive to pressure and tugging/manipulation. IV fenatnyl and IV morphine were given along with IV propofol. When uterus was internalized, patient felt more pressure that seemed unbearable. More IV pain meds were given. Suggestion was made for intraperitoneal chloroprocaine. Patient able to tolerate fascial closure as well as staple skin closure.
