This is a dog study: It looked at Vital signs and heart rate comparing skin incision response . Remember what we know is that Co2 lasers are being used in the Vet and Human community, but not for the same reasons. I wiped out some info so have to go back and try and recreate it.
I have contacted Aesculight that provided the C02 laser for this study. The have a veterinary division and a medical division(humans). This person is in charge of both divisions. She should have a good handle on what's happening in the USA. Hopefully she will call soon.

Objectives: The study based on dog model animal, aims to evaluate if there are differences in the hemodynamic responses between patients submitted to skin incision with a blade scalpel and with a CO2 laser, using measurement changes in heart rate (HR) and arterial blood pressure (ABP) (including systolic-SAP, diastolic-DAP, and median-MAP) associated with different patient pain level perceptions during surgical procedures.
Methods: A sample of 50 dogs (N=50) of both genders, aged between one and five years, with no cardiovascular diseases, but with a soft tissue surgical clinical condition was used. The sample was divided into two groups each comprising 25 individuals. One group had midline skin incisions made with a scalpel (GS), and the other had midline skin incisions made with a CO2 laser (GL), specifically an Aesculight®. The study design considered only one surgical time point, T1 (midline skin incision), at which HR and ABP-SAP, DAP, and MAP-were measured using a high definition oscillometry (HDO) device, which allowed a fast and accurate read of the parameters. For statistical analysis, P-values <0.05 were considered significant.
Results: All the patients presented the same pattern variation for the HR and ABP, with lower values being recorded for patients which had the midline skin incision made with the CO2-laser. The variations between GL and GS were statistically significant with a value of P<0.001 for all the ABP parameters, but not for HR (P=0.12).
Conclusions and Relevance: Our results indicate that the use of CO2 laser in surgery surpasses the conventional scalpel, by lowering the nociceptive system stimulation, decreasing the autonomic nervous system activity and stabilizing the hemodynamic clinical signs such as the SAP, DAP, and MAP, which in turn promote reduced anesthetic consumption and thus offer greater safety to the patient.
