Proof of causation in a criminal malpractice case

Facts and context

Three-year-old Gerald Gercayo, who had been born with an imperforate anus, was admitted to Ospital ng Maynila for a pull-through operation. The surgical team included several surgeons and three anesthesiologists, among them Dr. Fernando Solidum. During the operation Gerald developed bradycardia, went into a coma, and later emerged with hypoxic brain injury that left him unable to see, hear, speak, or move.

The prosecution charged only Dr. Solidum with reckless imprudence resulting in serious physical injuries. It alleged that he had failed to monitor and regulate the anesthesia and had caused Gerald’s cardiac arrest. The trial court and Court of Appeals convicted him, relying substantially on the child’s condition and an inference of negligence under res ipsa loquitur. The record, however, contained competing accounts of the anesthetic agents used, who administered them, and what caused the bradycardia and hypoxia.

Issue

Did the prosecution identify a negligent act attributable to Dr. Solidum and prove beyond reasonable doubt that it caused Gerald’s hypoxic injury? Could the injury itself supply the missing proof through res ipsa loquitur?

Ruling and doctrine

The Court acquitted Dr. Solidum. The prosecution did not reliably establish which anesthetic agent caused the event, that Dr. Solidum had improperly administered it, or that the child’s bradycardia and hypoxia resulted from a breach attributable to him. Because the medical mechanism and the allocation of responsibility remained disputed, the occurrence was not one from which negligence could simply be inferred through common knowledge.

The Court also removed the civil award because the evidence in that case supplied no competent basis for assigning the injury to Dr. Solidum. That disposition does not mean that every criminal acquittal automatically extinguishes civil liability; the reason for the acquittal and the asserted source of the civil obligation still matter.

Practice implications

Parao Law practice guidance

For physicians

• Keep a contemporaneous account of observations, medication administration, monitoring, deterioration, and interventions during anesthesia and recovery.
• After an adverse event, distinguish what was directly observed from suspected causes. Record uncertainty honestly rather than adopting an unconfirmed mechanism as fact.
• Preserve relevant clinical and equipment records through the appropriate institutional process so the event can be reconstructed.
• Conduct a structured review of disease, procedure, medications, equipment, and response. An injury label such as hypoxia does not identify the cause or the responsible person.

For lawyers

• Identify the precise negligent act alleged and obtain expert evidence linking it to injury; do not rely on disability or death alone.
• For res ipsa loquitur, establish an event ordinarily inconsistent with due care, control of the injuring instrumentality, and absence of patient contribution. Solidum lacked the first foundation.
• Test alternative mechanisms against the anesthesia record and testimony. Establish which doctor controlled the activity in question.
• Analyze criminal and civil consequences separately. The required criminal proof and the Court’s civil disposition must both be addressed.

Limits of the ruling

The decision is not a categorical prohibition on res ipsa loquitur in every criminal malpractice case. Its rejection of the inference rested on the missing foundation in these circumstances. An unfavorable outcome, a rare event, and a legally justified negligence inference are not interchangeable.
