Zheng Ren reached out and an uncovered aspirator was placed in his hand.
In the surgical field, blueish-green pus was visibly leaking out from the ileocecal fossa.
He hesitated before putting the aspirator on the patient's thigh. "Pass me a scraper."
"Yes." Xie Yiren blinked and passed him the tool before picking up some sterile gauze.
Zheng Ren did not drain the pus by suction. Instead, he scraped at it and wiped it off on the gauze in Xie Yiren's hand.
It was a sample for subsequent microbiological culture. Xie Yiren had understood his intentions without a word.
Even though the greenish pus in the ileocecal fossa seemed to be caused by infection by Pseudomonas aeruginosa, they could not confirm it until they performed a test.
After collecting the sample, Zheng Ren began draining the rest of the pus with the aspirator.
Xie Yiren carefully put the contaminated tools aside and organized the sterile tools for closure later.
