[Infant boy with propionic acidemia: anesthetic implications].
A 12-month-old boy diagnosed with propionic acidemia underwent gastrostomy. The patient's general state was good and he was alert, but with reduced muscular tone (unstable when seated with support, floppy head) and with dystonic movements in all extremities. An electroencephalogram showed slightly slowed brain activity. The patient was being treated with a low protein diet, phenobarbital, L-carnitine, L-isoleucine, and biotin. Surgery was carried out in satisfactory conditions with general anesthesia without opioids combined with infiltration of the surgical wound with local anesthetic. Recovery from anesthesia was rapid and free of complications. Propionic acidemia is caused by mitochondrial propionyl coenzyme carboxylase deficiency. Most patients have episodes of severe metabolic ketoacidosis as a result of excessive protein intake, delayed development, vomiting, gastroesophageal reflux, lethargy, hypotonia, and convulsions. The anesthetic approach involves avoiding triggers of metabolic acidosis (such as fasting, dehydration, hypoxemia, and hypotension) and preventing airway complications. Agents that metabolize propionic acid (such as succinylcholine, benzylisoquinoline neuromuscular blocking agents, and propofol) are not used, as they can exacerbate acidemia. We also believe that using local or regional anesthesia in combination with general anesthesia without opiates is safe and effective for controlling pain during surgery and postoperative recovery, as that combination avoids respiratory depression in these patients, who are highly sensitive to opiates.
