Over the weekend the normally fit and healthy man’s health declined and on Monday morning he collapsed in the shower.
“I heard this almighty crash and went in to see him sliding down the shower door,” Holmes said.
“He was rushed to the hospital by ambulance and when we were there the results came back from the cut to his head and it was a staphylococcus infection.”
Doctors found the bacterial infection had already developed into sepsis - a life-threatening condition where the body responds incorrectly to an infection and damages its own tissues and organs.
The sepsis infection had travelled through Runga’s body and attacked his left knee - the site of a cartilage surgery after a rugby injury 20 years earlier.
“It attacked his knee so badly he had to have three washouts and an aspiration of his knee which was incredibly painful,” Holmes said.
“He went on to have seven operations, a bone graft, and at one stage they were talking about amputating his leg.
“It was just horrific. It is crazy that it was caused by a nick on the back of his head.”
Holmes contacted the barbershop when her husband was in hospital and spoke to the manager about the importance of equipment hygiene.
“I didn’t blame anyone because it is just one of those things but we have been back and noticed it is all a lot cleaner now.
Last week Accident Compensation Corporation (ACC) released figures that showed up to 30 people a year seek medical treatment after a laceration injury at the barber or hair salon.
There were 155 new claims and 141 active claims since the beginning of 2018 costing more than $28,000.
“If it gets to that stage, or if there is fever, you need to see a general practitioner and get an oral antibiotic which is more effective than anything topical.”
