The state medical board on Tuesday revoked the license of a Stamford family doctor accused of performing cosmetic procedures without the proper training, qualifications, staff or equipment, citing an “overabundance” of examples that his conduct demonstrated “a profound misunderstanding of the practice of medicine.”

The charges against Dr. Efraim Gomez-Zapata, 58, stemmed from his care of eight patients, one of whom had a seizure on his operating table and another who went into respiratory arrest, which a board member said might have occurred after Gomez-Zapata injected spinal anesthesia into the wrong part of the woman’s back.

Board member Dr. David Goldenberg, who was chairman of a hearing panel for the case, said that revoking Gomez-Zapata’s license was necessary to protect the public. He said that Gomez-Zapata had deceived himself and his patients about his abilities, lacked the training, knowledge and backup staff necessary for the procedures he performed, and failed to accept responsibility for what happened to his patients, two of whom Goldenberg said could have died if not for the help of emergency medical workers.

“The summary of Dr. Gomez’s backup plan for these patients was three numbers: 911,” Goldenberg said.

Gomez-Zapata’s attorney, John J. Evans, called the revocation unfair.

“There’s really no evidence that he harmed anybody,” Evans told the board, adding that the patients who had complications recovered.

After the vote, Evans disputed Goldenberg’s description of the case and suggested that the board had a separate agenda.

“I believe the medical board wants to take any aesthetic medicine out of the realm of general physicians who are currently licensed to do aesthetic medicine and relegate it only to plastic surgeons,” he said.

Gomez-Zapata has acknowledged that he did not have a license to run an outpatient surgical facility, saying he did not know he needed one. He signed an order in 2008 that prohibited him from performing surgery with moderate or deep sedation.

Evans acknowledged Tuesday that Gomez-Zapata’s record-keeping could have been better. But he and Gomez-Zapata disputed the other charges. The woman who had the seizure, who was to receive an abdominal liposuction, had a history of seizures that she failed to mention, Gomez-Zapata told the hearing panel last year. The woman who went into respiratory arrest probably had an allergy to anesthesia, he said.

The board apparently was not convinced. A written decision said that Gomez-Zapata “blatantly ignores the facts” and that he demonstrated a “lack of knowledge, poor judgment and reckless disregard for the health and safety of his patients.”

The state Department of Public Health began investigating Gomez-Zapata in 2007 after getting a report from Stamford Hospital that a woman had been taken to the emergency room from Gomez-Zapata’s office. The woman had a seizure after Gomez-Zapata administered a painkiller, anxiety drug and local anesthesia, according to state records.

Disciplinary charges against Gomez-Zapata also cited the case of the woman who went into respiratory arrest and two other patients who received cosmetic procedures.

Health officials added more charges last year after learning that Gomez-Zapata was allegedly performing liposuction using local anesthesia — a violation of medical standards, the department charged. Gomez-Zapata testified that he was following the order not to use moderate or deep sedation, and that he was not performing liposuction but removing substances that other doctors had implanted into his patients’ bodies.

Gomez-Zapata has been barred from practicing medicine since last May, when the medical board suspended his license. The board can suspend a doctor’s license before disciplinary proceedings are completed if it believes that a physician’s actions represent an immediate danger to the public.
