Protecting an infant from pain may be a matter of instinct. In a new study, researchers show that gently stroking babies during medical procedures, as parents intuitively do, reduces infants’ feelings of pain about as well as applying a topical anesthetic. The discovery suggests touch and tactile stimulation are effective means to mollify pain in newborns and an alternative to using drugs.

“Touch seems to have analgesic potential without the risk of side effects,” Rebeccah Slater, a pediatric neuroscientist at the University of Oxford in the United Kingdom, who led the new research, said in a statement.

Soothing Strokes

Touch has the power to sooth, especially skin-to-skin contact. Gentle and slow stroking of hairy skin activates a class of sensory nerves called C fibers. In adults, stimulating these fibers not only feels good, but also alleviates pain. Slater and her colleagues wondered if the same might be true for infants.

The researchers observed two- to five-day old infants as they were poked and prodded for medical tests. The babies received pinpricks and lances to collect blood from their heels. The team measured the newborns’ brain activity with electroencephalography, a technique that records electrical activity on the surface of the brain, during the procedures.

Right before the tests, researchers brushed the infants at about an inch per second (the optimal speed to activate the C fibers) or a speed about 10 times faster.

Tactile Therapy

Compared to infants that were not touched before receiving pinpricks, brain activity in response to pain decreased 60 percent in the infants stroked at the optimal rate, Slater and colleagues report today in the journal Current Biology. Stroking babies at the faster rate did not have this effect. The team saw a similar outcome when lancing the babies’ heels to collect blood.

“Parents intuitively stroke their babies at this optimal velocity,” Slater said. “If we can better understand the neurobiological underpinnings of [touch] techniques like infant massage, we can improve the advice we give to parents on how to comfort their babies.”

Slater and colleagues also watched the babies’ faces before the heel lancing procedure. They found all the babies grimaced when lanced, but babies that were not touched grimaced for almost 50 percent longer than babies that received caresses.

The findings suggest tactile stimulation can reduce pain in infants and could facilitate pain management care for newborns.

Today’s letters: ‘Visionary’ plans don’t always work in Ottawa

The opinion piece written by Tobi Nussbaum, CEO of the NCC, declares that a “bold, visionary transit plan” would showcase the capital.

As a long-term resident of Ottawa, I’ve had it with visionary plans. In the 1950s, the streetcars serving Ottawa so well were sent to the scrapyards. In the early ’60s, Queensway construction bulldozed established neighbourhoods and ripped the city apart. Later in the decade, the downtown railway station, which could have formed the hub of a commuter network, was relocated to the suburbs. These actions, in the name of “progress,” were undertaken with the “vision” to make Ottawa a car-reliant city.

Now we have an LRT, built just in time for most people to realize that they do not have to go downtown as they can work from home.

Current thinking is pushing a new “link” between Ottawa and Gatineau, with yet more expensive and disruptive infrastructure projects being touted, including a tramway or another tunnel under the downtown core.

That was then: Biggest earthquake since 1653 rocked Ottawa in 1925

A regular weekly look-back at some offbeat or interesting stories that have appeared in the Ottawa Citizen over its 175-year history. Today: The big one hits.

The Ottawa Senators were playing a Saturday night game against the Montreal Canadiens at the Auditorium, the score tied 0-0 halfway through the second period. Sens’ rookie Ed Gorman and the Habs’ Billy Boucher had just served penalties for a dustup when the building began to make “ominous creaking sounds.” A window crashed to the ground.

Nearby, at Lisgar Collegiate, all eyes were on teenager Roxie Carrier, in the role of Donna Cyrilla in the musical comedy El Bandido. She had the stage to herself and was singing “Sometime” when the building rocked, the spotlight went out, and someone in the audience yelled “Fire!”

At a home on Carey Avenue, one woman’s normally relaxed cat suddenly arched its back, rushed around the room two or three times, spitting angrily, and climbed up the front-window curtains.

Ottawa delays small nuclear reactor plan as critics decry push for new reactors

TORONTO — Canadians will have to wait a little while longer to see the federal government’s plan for the development of small nuclear reactors, seen by proponents as critical to the country’s fight against global warming.

Speaking at the opening of a two-day virtual international conference on Wednesday, the parliamentary secretary to the minister of natural resources said the plan will lay out key actions regarding the reactors. Its launch, Paul Lefebvre said, would come in the next few weeks.

“We’re still putting the finishing touches on it,” Lefebvre said. “The action plan is too important to be rushed.”

Small modular reactors — SMRs — are smaller in size and energy output than traditional nuclear power units, and more flexible in their deployment. While conventional reactors produce around 800 megawatts of power, SMRs can deliver up to 300 megawatts.

Proponents consider them ideal as both part of the regular electricity grid as well as for use in remote locations, including industrial sites and isolated northern communities. They could also play a role in the production of hydrogen and local heating.

“SMRs will allow us to take a bold step of meeting our goal of net-zero (emissions) by 2050 while creating good, middle class jobs and strengthening our competitive advantage,” said Lefebvre.

Natural Resources Minister Seamus O’Regan had been scheduled to speak at the conference but did not due to a family emergency.

Industry critics were quick to pounce on the government’s expected SMR announcement. They called on Ottawa to halt its plans to fund the experimental technology.

While nuclear power generation produces no greenhouse gas emissions, a major problem facing the industry is its growing mound of radioactive waste. This week, the government embarked on a round of consultations about what do with the dangerous material.

Dozens of groups, including the NDP, Bloc Quebecois, Green Party and some Indigenous organizations, oppose the plan for developing small modular reactors. They want the government to fight climate change by investing more in renewable energy and energy efficiency.

“We have options that are cheaper and safer and will be available quicker,” Richard Cannings, the NDP natural resources critic, said in a statement.

Lefebvre, however, said the global market for SMRs is expected to be worth between $150 billion and $300 billion a year by 2040. As one of the world’s largest producers of uranium, Canada has to be part of the wave both for economic and environmental reasons, he said.

“There’s a growing demand for smaller, simpler and affordable nuclear technology energy,” Lefebvre said.

Joe McBrearty, head of Canadian Nuclear Laboratories, told the conference the company had signed a host agreement this week with Ottawa-based Global First Power for a demonstration SMR at its Chalk River campus in eastern Ontario. A demonstration reactor will allow for the assessment of the technology’s overall viability, he said.

“When talking about deploying a new technology like an SMR, building a demonstration unit is vital to the success of that process,” McBrearty said. “Most importantly, it allows the public to see the reactor, to kick the tires so to speak, and to have confidence in the safety of its operation.”
