An emergency room physician in British Columbia is warning of the misuse of a cooking tool that requires the use of nitrous oxide, more commonly known as laughing gas.

A statement from Vancouver Coastal Health says Dr. Matthew Kwok reports seeing patients at Richmond Hospital who have intentionally inhaled the gas and suffered drug-induced psychosis and neurological effects.

Nitrous oxide is used in medical and dental offices for sedation and pain, but it is also readily available in small canisters, called whippits, that are attached to a kitchen utensil used to whip cream.

Kwok says addiction to nitrous oxide is possible and non-medical use of the gas can be “extremely dangerous.”

In the December issue of the B.C. Medical Journal, Kwok reports that no single agency in Canada is tracking non-medical overdoses, despite the dangers posed by the gas which is easily purchased.

Kwok is calling for restricted access to nitrous oxide, safeguards to minimize harm and greater awareness by medical staff and the public about non-medical use of laughing gas.

“When people present at the emergency department with unexplained neurological symptoms it’s important for clinicians to consider nitrous oxide as a possible cause,” Kwok says in the statement.

The article in the B.C. Medical Journal outlines the case of a 20-year old woman who was hallucinating but had no history of psychiatric or medical illness, although she admitted to daily use of nitrous oxide, and had recently increased her dosage.

“It’s also important for users to know that using this product outside a supervised medical setting can cause serious health effects,” says Kwok.

Coronavirus: 7 people linked to Toronto restaurant test positive, around 1,700 possibly exposed – Global News

Published

on


Toronto Public Health (TPH) officials say seven people linked to a downtown restaurant have tested positive for the novel coronavirus and officials are now asking approximately 1,700 people to monitor for symptoms of COVID-19.

Officials said five staff members and two patrons of Yonge Street Warehouse — located near Yonge and Dundas streets — are confirmed to have contracted the virus.

All known close contacts of those individuals have been reached by TPH, officials said, adding that anyone who hasn’t been contacted is considered low risk.

TPH said the period for potential exposure is from Sept. 10 to 17 — it’s estimated around 1,700 people may have attended the restaurant during that time.

Anyone who was at the establishment during that period is being asked to monitor for symptoms of COVID-19 for 14 days since their last visit “as a precaution.”

“If symptoms develop, please contact TPH, seek testing and immediately self-isolate,” officials said.

7 COVID-19 cases linked to Yonge Street Warehouse – CBC.ca

Published

on


Toronto Public Health (TPH) says seven people who have tested positive for COVID-19 went to a Yonge Street restaurant within the last month.

Of the seven, five are staff members and two are patrons. All of which attended Yonge Street Warehouse, at 336 Yonge St., between Sept. 10 and Sept. 17.

The health agency wants to notify staff and patrons who visited the restaurant during the 8-day period about a potential exposure to the virus. 

TPH said they have followed up with all known close contacts and those individuals have been asked to self-isolate for 14 days and go for testing. 

Around 1,700 people may have been at the venue during this time, TPH said, however, people not already contacted are viewed as low risk.

“If you were at the Yonge Street Warehouse between September 10 to 17 but have not been contacted by TPH, you are not identified as a close contact,” read a statement released on Saturday.

Nevertheless, the health agency is still urging anyone who was there during the exposure time to monitor themselves for symptoms for 14 days after their last visit. 

If symptoms develop, the agency asks you to contact TPH, seek testing and immediately self-isolate.
