Apr 9, 2024 · Anesthesia affects everyone differently, especially redheads. People with naturally red hair may be more sensitive to pain and require more anesthesia.
Apr 19, 2022 · Researchers are still learning about how anesthesia affects people with red hair. If redheads do need higher doses of anesthesia, there are some possible health effects to consider.
Jul 1, 2022 · There is a school of thought that says redheads require more local anesthetic to manage pain, as well as increased amounts of general anesthesia to induce unconsciousness, than the rest of the population.
Apr 20, 2021 · These mice show higher tolerance to pain. By crossing the red-haired mice with an albino strain to prevent melanin synthesis, the scientists were able to study the role of pigment. They found that mice carrying the MC1R red-hair variant had a higher pain threshold even without pigment synthesis.
Introduction. Inhalational anesthetic requirements are remarkably uniform in humans, mainly being affected by age and body temperature. 1, 2 However, some anesthesiologists share an anecdotal impression that patients with natural red hair require more anesthesia than patients with other hair colors.
Anesthetic requirement in redheads was increased 19%, a difference that was highly statistically significant ( P = 0.0004). The results confirm anecdotal clinical impressions that anesthetic requirement is greater in redheads.
Studies have reported that: Redheads need about 20% more anesthesia to be sedated. Redheads need more subcutaneous local anesthetics to be effective. Redheads are less sensitive to electric shock. Redheads are more sensitive to pain-killing analgesics such as opioids.
Nov 6, 2023 · You may have heard that, from the dental chair to the labor-and-delivery room, things hurt worse for redheads. But do redheads really experience pain differently than other people?
Feb 5, 2022 · Redheads and anesthesia: Analyzing the differences in pain perception. Feb. 5, 2022. The science on redheads and their sensitivity to pain is complicated. Anne Nugent Guignon, MPH, RDH, CSP, investigates how current research translates to pain management and anesthesia delivery.
Jan 30, 2015 · There were no clinically important differences in anesthetic sensitivity between redheads and patients with other hair colours. Among the outcomes tested by Gradwohl et al ., the relationship between MAC and BIS is probably the most sensitive for potential effects of red hair on anesthesia.
