LED Surgical headlights are standard in emergency rooms

Throughout Enova’s 10th Anniversary Year, Shedding Light is connecting with surgeons and physicians who were featured over the past three years in the online newsletter. This month we caught up with Dr. David M. Larson, an emergency physician who is Medical Director of the Ridgeview Emergency Departments at the Ridgeview Medical Center in Waconia and at Two Twelve Medical Center in Chaska, both located in Minnesota.

Dr. Larson was one of the first users of Enova’s first headlight, the Halo 5000 when it came out in 2005. At the time he was featured in Shedding Light, he and his staff were using Enova’s Iris S-100 surgical headlight in addition to the Halo 5000. While the Halo still functions, Dr. Larson chose to upgrade to one of Enova’s newest headlights, the Cyclops XLT-125 to supplement the S-100 in the emergency room.

We asked him a few questions and included the original article published in June 2013.

Shedding Light: Does your Halo 5000 still work?

Dr. Larson: It works, but it’s not as comfortable or as easy to use as the newer XLT-125. We’d used the Halo headlight for 10 years, which is pretty remarkable.

Shedding Light: How do you like the Cyclops XLT-125?

Dr. Larson: It is very lightweight–unlike the Halo headlight, which has the batteries on the headlight band–and the batteries are easily slipped onto a waistband or into a scrubs pocket. The illumination is exceptional and brighter than any of our previous Enova headlights. And, it is absolutely better than a fiber optic headlight. It allows us to move around a patient with no cords.

Shedding Light: What do you use the XLT-125 for in the emergency room?

Dr. Larson: It is great for ENT procedures and surgical procedures. I especially like how the XLT-125, once the lamp is set to my preferred height on my head and at the perfect coaxial position, it follows my line of site but keeps the beam of light out a a patient’s eyes. It is very focused.

In June 2013, Shedding Light talked with Dr. Larson about the demands of emergency care, his mission work, and how Enova surgical headlights help him on the job and in the field. Here is that published interview.

Shedding Light:  What makes emergency care different from other kinds of medical care?

Dr. Larson:  Every day is different from the one before. We see all ages and kinds of patients in the emergency room and in urgent care from minor conditions such as strep throat, ear infections and allergies to life-threatening conditions like heart attacks, orthopaedic injuries, and major bleeding from wounds. We diagnose and treat on the spot. Some patients are transferred to the hospital for further care and others are discharged with treatment instructions.

Shedding Light: What is the scope of your practice at Ridgeview?

Dr. Larson: Ridgeview has two emergency departments. One is at the Ridgeview Medical Center in Waconia, Minnesota, and the other is at Two Twelve Medical Center in Chaska, Minnesota. I oversee both departments.  We see approximately 50,000 patients in the emergency room each year; about 20,000 at the Waconia location and 30,000 at the Two Twelve location, which is only three years old.  The Two Twelve Medical Center also has 24/7 urgent care available. Both locations are supported by on-site diagnostic imaging, trauma bays, a helicopter pad and critical care specialists.

Shedding Light: How has technology improved care in the emergency room?

Dr. Larson: Technology has had a huge impact on how quickly we can assist patients in the emergency room. Some that come to mind are electronic medical records, accessible databases of information, diagnostic equipment such as the bedside ultrasound, and of course, imaging technology such as MRI and CT scans are all advances that have improved how we care for patients in the emergency room.

Shedding Light: How do you use a surgical headlight in the emergency room?

Dr. Larson: Using a headlight is becoming standard in emergency care. We often perform laceration repair as well as minor surgeries. The headlight needs to provide excellent illumination and have an adjustable light spot to focus on small cavities. We often go from room to room, which makes a portable headlight preferable.

Shedding Light: When did you first begin using an Enova LED surgical headlight?

Dr. Larson: I was one of the first users in 2005 when the Halo 5000 came out. Today we use the Iris S-100. Before purchasing an Enova headlight, we would use the OR’s fiber optic light but it wasn’t always readily available and it’s tethered to a stand so it’s not as portable as I’d like.

Shedding Light: What kind of mission work do you do?

Dr. Larson: For the past four years I’ve traveled to Haiti with a team of general surgeons as part of a group mission. We perform general elective and gynecological surgeries such as hysterectomies and hernia surgeries. I usually bring my headlight and Enova has donated a headlight as part of their mission program.

Shedding Light: How often do you use your Enova headlight each week?

Dr. Larson: The emergency room is available 24/7 and we use the Iris S-100 every day.

Shedding Light: Do you recommend the Enova LED surgical headlight to your colleagues?

Dr. Larson: Yes. Now that I’ve used both the Halo and the S-100, I recommend the S-100 over the Halo.* It is extremely portable and easy to use. The light is superior and the battery pack is easily rechargeable for continued use. As I said earlier, the surgical headlight is becoming standard in emergency care and the Enova LED headlight is my headlight of choice.
