G.R. No. 192123 March 10, 2014
DR. FERNANDO P. SOLIDUM, Petitioner, vs. PEOPLE OF THE PHILIPPINES, Respondent.

FACTS

Gerald Albert Gercayo, born on June 2, 1992 with an imperforate anus, underwent a colostomy two days after birth. On May 17, 1995, at three years old, he was admitted to Ospital ng Maynila for a pull-through operation. Dr. Leandro Resurreccion headed the surgical team, and the anesthesiologists included Dr. Marichu Abella, Dr. Arnel Razon, and petitioner Dr. Fernando Solidum. During the operation, Gerald experienced bradycardia, went into a coma for two weeks, and regained consciousness only after a month, left incapable of seeing, hearing, or moving. His mother, Ma. Luz Gercayo, lodged a complaint for reckless imprudence resulting in serious physical injuries. An information was filed solely against Dr. Solidum, alleging he failed to monitor and regulate properly the levels of anesthesia, using 100% halothane, causing cardiac arrest and hypoxic encephalopathy. The Regional Trial Court (RTC) found Dr. Solidum guilty beyond reasonable doubt, sentencing him to an indeterminate penalty and ordering him to pay damages. The Court of Appeals (CA) affirmed the conviction, applying the doctrine of res ipsa loquitur.

ISSUE

1. Whether the doctrine of res ipsa loquitur was applicable.
2. Whether Dr. Solidum was liable for criminal negligence.

RULING

The Supreme Court granted the appeal and ACQUITTED Dr. Fernando P. Solidum.
1. On the applicability of res ipsa loquitur: The Court held the doctrine was improperly applied. Res ipsa loquitur is a mode of proof, not a substantive rule, and does not dispense with the requirement of proving culpable negligence. It applies only when direct evidence is absent and not readily available. In this case, the prosecution presented expert witnesses, making the doctrine inapplicable. Furthermore, the doctrine of common knowledge, which res ipsa loquitur is tied to, could not be invoked because the question of whether a three-year-old boy with imperforate anus should be given halothane and the determination of the cause of his brain damage required expert medical testimony, being beyond the ken of an average layperson.
2. On the liability for criminal negligence: The Court found that the prosecution failed to prove Dr. Solidum’s guilt beyond reasonable doubt. The evidence did not establish that Dr. Solidum administered 100% halothane as alleged; testimony indicated the anesthesia machine regulated the mixture, and the concentration used was 1% halothane with oxygen. The prosecution’s expert witness, Dr. Edgardo Ortiz, could not definitively state that the brain damage was caused by the anesthesia or that there was an overdose. The defense presented credible expert testimony from Dr. Eduardo Jamora, who explained that bradycardia could be caused by the vagal reflex triggered by surgical traction, a known complication, and that the anesthesia team appropriately managed the situation. The Court emphasized that in medical negligence cases, the plaintiff must prove by expert testimony the standard of care, its breach, and the causal connection between breach and injury. The prosecution failed to discharge this burden. The constitutional presumption of innocence prevailed.
