The death of Clara Nunes occurred on April 2, 1983, and was caused by anaphylactic shock triggered by halothane at the São Vicente Clinic in Rio de Janeiro.

[1][4][5] After undergoing a hysterectomy in 1979 due to a proliferating myoma in her uterus, Clara Nunes started receiving sclerotherapy treatment, which consists of injecting medication directly into the varicose veins.

In June 1982, after performing at the Horizonte Latin American Art Festival in West Berlin, Clara phoned her friend Bibi Ferreira from the hotel room where she was staying to tell her that she was worried about her varicose veins.

According to her husband Paulo César, who found out about the surgery in late February, Clara decided not to have epidural anesthesia because she was afraid of becoming paralyzed if there was a medical error.

The doctors tried to convince her to abandon the idea, explaining the advantages of the epidural, and that general anesthesia, in the case of small surgeries, could cause complications.

[5] As soon as the information about Clara's state of health was published, Engenheiro Alfredo Dutra Street, where she lived, and the São Vicente Clinic were crowded with reporters.

At this point, it had already been reported that Clara had suffered anaphylactic shock as a result of surgery, but different versions of the motives behind her surgical procedure began to circulate, such as artificial insemination, abortion and a suicide attempt.

Rosemary, Elizeth Cardoso, Dori Caymmi, Grande Otelo, João Nogueira, Dona Zica, Mauro Duarte, Fafá de Belém, Paulinho da Viola, Luiz Ayrão, Roberto Ribeiro, Alcione, Elza Soares, Beth Carvalho, Chico Buarque, Marieta Severo and Baby Consuelo are among the artists who went to the clinic.

[5] Baby Consuelo had one of the most tense moments when she tried to enter the ICU with Thomaz Green Morton, a medicine man who had convinced several artists that his "paranormal powers" cured serious illnesses.

One of the few medicine men he allowed into the ICU was the Chinese acupuncturist Mister Wu, who tried to revive Clara using an acupuncture technique called moxibustion.

Faced with Paulo César's silence and the uninformative medical reports, the media demanded that the doctors hold a press conference and that the operating room be opened for an inspection of the equipment.

There were suspicions that the anesthesiologist Américo Salgueiro had been absent from the room during the surgery, that a medical error had occurred in her care and that there had been a failure in the equipment that released oxygen.

Maria Gonçalves and Paulo César Pinheiro contacted Portela's president, Nezinho, to arrange for the funeral to take place at the school's headquarters in Madureira.

Meanwhile, programming on Brazil's main television networks was interrupted with live flashes from the clinic and the Portela's court; on the radio, the hits from Clara's latest album, Nação, played incessantly.

A fire department truck took the coffin to the São João Batista Cemetery, where Clara was buried at 6pm after a small uproar at the time of her arrival due to the large number of people who had gathered there.

According to Edir Macedo, founder of the Universal Church of the Kingdom of God and current owner of Record, the demonic possession was revealed during an unloading session held in one of his temples.

[5][9][7] Paulo César Pinheiro decided not to file a lawsuit against the doctors who treated Clara for medical malpractice since he had to authorize the exhumation of her body, which she had expressed her disapproval of before she died.

[5][10] The intervention in Cremerj began when two opposition parties disregarded a rule issued by Murilo Belchior, former president of the CFM, which banned the inclusion of candidates with less than five years of training on the ballot.

The documents include Américo Salgueiro's version of the anaphylactic shock, the testimonies of each of the team members who worked on the surgery and those of other witnesses mentioned in news reports, and the medical records detailing which drugs were given to Clara during the 28 days she was hospitalized at São Vicente Clinic.

Cremerj's provisional board had decided to gather newspaper clippings and request reports on the case from doctors Antonio Vieira de Mello, Américo Salgueiro Filho and Jacob Cukier (then head of the clinic's ICU).

On June 27 and 28, Paulo César Pinheiro, members of the surgical team and directors of the clinic testified to Fernando Marigliano and Artur Ventura, from Cremeb, at Cremerj's former headquarters in Rio de Janeiro.

When asked if any doctors were in the call center at the time of the operation, she said she didn't know, because her shift started at noon (one hour and fifteen minutes after the surgery began).
