Dr Nik Mohd Adzrul Ariff said he gave Jong Nam atropine and adrenaline to boost his situation.
“After his seizure stopped, he was unconscious but his blood pressure was still present,” the fourth prosecution witness said, adding that he administered the medications as it might increase Jong Nam’s heartbeat and ability of the heart to contract stronger.
In his testimony yesterday, he said Jong Nam suffered a seizure when he was sent to his clinic and was clutching his head with his eyes closed.
His face was red and sweating profusely.
Adzrul said today although he gave Jong Nam two medications, his oxygen level remained low.
“Although his vital signs showed improvement, the oxygen level was still unstable. So I did not transfer him to Putrajaya Hospital,” he said during examination-in-chief by deputy public prosecutor Wan Shaharudin Wan Ladin.
Adzrul said he proceeded to try to insert a tube into Jong Nam’s trachea to pump in more oxygen.
“However, when I opened his mouth, I saw there was a mixture of saliva, blood, vomit and mucus inside.
“I had to suck out the mixture before putting a tube into his mouth,” he said.
He added the incubation process of pumping oxygen succeeded as Jong Nam’s oxygen level had increased to 94%.
“I admitted him to hospital as he needed to be treated under an ICU setting after his condition improved as blood pressure was 108/70 and pulse showed 90 to 100 beats per minute,” he said.
Two women, Indonesian Siti Aisyah, 25, and Vietnamese Doan Thi Huong, 29, are standing trial for murdering Jong Nam, the estranged half-brother of North Korean supreme leader Kim Jong Un on Feb 13.
The eldest son of former North Korean leader Kim Jong Il, arrived in Malaysia on Feb 6, and was scheduled to board a 9am flight to Macau the day he was killed.
He died on the way to Putrajaya Hospital, sparking a diplomatic row between Putrajaya and Pyongyang.
During the opening statement of the trial on Monday, the prosecution said they would prove the two women approached Jong Nam at the airport’s departure hall and sprayed VX nerve agent on his face.
Deputy public prosecutor Iskandar Ahmad told the court the actions of Siti Aisyah and Doan showed they both intended to cause Jong Nam’s death.
During cross-examination by Doan’s lawyer Hisyam Teh, Adzrul said Jong Nam’s eventual cause of death was cardiac arrest, due to respiratory failure.
Another of Doan’s lawyers Naran Singh asked the doctor if police had questioned him after Jong Nam’s visit to the clinic to which he said “yes” but the authorities did not ask for the referral letter to send him to hospital.
Adzrul added he did not keep a copy of the letter.
Another witness, pathologist Dr Norashikan Othman, told the court she did an analysis of samples from Jong Nam and the two women on their level of the cholinesterase enzyme, and found Jong Nam’s enzyme level was lower than the women’s.
“His enzyme level was at 344 units per litre while Siti and Doan were 6,781 and 7,163 units per litre respectively,” she said, adding that the women’s enzyme levels were normal.
Cholinesterase enzyme controls muscles and coordination of body movements.
A lack of the enzyme would lead to heart and muscle dysfunction.
Norashikin told the court that the VX nerve agent could cause a reduction of the amount of enzyme in the body.
The hearing will continue tomorrow before Justice Azmi Ariffin.
