Carolina was 0-for-2 on the power play and 5-for-5 on the penalty kill. Raanta made nine saves while short-handed, including a one-timer by DeBrincat from the left circle 38 seconds into the second during a 5-on-3.
"[The penalty kill] was huge," Raata said. "We know that they have skillful players, and they move the puck really well. Guys were doing a great job taking backdoor passes away, and when I had the shot, I was able to see it."
After being outshot 17-7 in the first, the Senators outshot the Hurricanes 25-13 over the final two periods.
"I think everybody is frustrated," Ottawa defenseman Thomas Chabot said. "At this point, we want to win games, we want to get in the mix. But you've still got to take some positive. The last 40 minutes were the way we play and that's the way we have success. Obviously, we couldn't find the back of the net."
Raanta made 12 saves in the third, including two on Brady Tkachuk at the top of the crease at 10:58 and 11:17 on a power play.
"When it's 2-0, you don't want to let any goals in because then it's going to get even tighter," Raanta said. "Obviously, the last couple minutes you start yelling a little bit more to take the guys out. You try to focus on the next shot and hope the clock runs out really quickly."
