Abstract
A 76-year-old female patient was scheduled for
tracheostomy. She suffered from progressive
general muscle weakness for 1 year, and diagnosed
with amyotrophic lateral sclerosis (ALS) last
month. She had dyspnea and difficulty with
swallowing. We planned bilateral superficial
cervical plexus block (SCPB) for regional
anesthesia. Bilateral SCPB was conducted with 0.5
% ropivacaine 20 ml (10 ml per each side) under
ultrasound guided. After confirming sensory
blockade, the operation had begun. For sedation and
adjuvant pain reduction, ketamine was administered
intravenously by intermittent bolus (0.5 mg/kg).
Spontaneous respiration was maintained without
any other complication until the end of operation.
