Administration of Sugammadex Intraoperatively in a Patient With a Congenital Myasthenic Syndrome: A Case Report.
Congenital myasthenic syndromes are a group of genetic neuromuscular disorders caused by mutations that impair synaptic transmission at the neuromuscular junction. Developing an anesthetic plan for patients with this diagnosis is difficult, as they are at risk for prolonged neuromuscular blockade. ⋯ We present the case of a 6-year-old boy with a congenital myasthenic syndrome who received sugammadex without complication. This case provides support for clinicians to consider sugammadex in these patients.

Following the placement of lumbar plexus and parasacral sciatic catheters for complex lower extremity surgery, a 19-kg child had dense sensory and motor blockades in the postanesthesia care unit. The surgical team felt obligated to exclude anatomically modifiable compression of the sciatic nerve and planned for surgical reexploration. Using an insulated short, beveled needle, direct electrical nerve stimulation distal to the parasacral sciatic block and proximal to the surgical site elicited tibial nerve motor function and confirmed nerve integrity. Peripheral nerve stimulation can be used to differentiate between the etiologies of motor blockade in time-critical situations.

Massive leaks in the anesthesia circuit may cause intraoperative hypoventilation and awareness; we experienced this with a disposable CO2 absorber in Perseus A500, which uses turbine ventilation to create positive-pressure ventilation. Consequently, manual ventilation was rendered impossible. ⋯ Absorbers should be checked before the exchange, and the econometer or reservoir bag's filling state should be monitored. Anesthesia providers should know an anesthesia machine's dynamics and breathing system to provide appropriate management of such a leak.

Pregnant patients with high-risk conditions including abnormal placentation or severe cardiovascular disease may require large-bore central venous access at the time of delivery. Central lines are generally inserted while obstetric patients are awake, either because neuraxial anesthesia is planned or to minimize fetal exposure to anesthetic medications. ⋯ This case series describes use of a superficial cervical plexus block (SCPB) to facilitate line placement in 4 pregnant women with high-risk conditions. SCPB is technically straightforward with low reported complication rates and should be considered for pregnant patients requiring large-bore central lines.

We describe a case of a complete endotracheal tube (ETT) transection due to patient bite. The patient was intubated for postoperative pneumonia; during weaning of sedation, the patient was unable to tolerate pressure support ventilation (PSV) due to agitation. ⋯ Utilizing a multidisciplinary approach, we provided respiratory support and performed nasopharyngolaryngoscopy (NPL) to identify and extract the foreign body. An algorithm for management of ETT fragment extraction is provided.
