The effect of smoking on muscle transposition

Abstract:
Smoking has been shown to be a complicating factor in normal wound healing. Both nicotine and carbon monoxide adversely affect multiple stages of the healing process. From 1976 to 1990, 1034 muscle flap procedures were performed on 722 patients on a single surgical service. A retrospective review of 300 patients completed; patients were divided into three groups: group 1, no smoking history; group 2, smokers for at least 10 pack/years but had quit for at least 1 year; and group 3, active smokers at the time of surgery. Patients were omitted who had diabetes, had received radiation therapy or chemotherapy, had a recurrent malignancy, or used steroids. A total of 300 consecutive patients were entered into the study. Active smokers were shown to have a complication rate significantly higher in the immediate postoperative period compared with nonsmokers and smokers who had quit. The most common complications were partial muscle necrosis and partial skin graft loss. This series suggests that active smoking at the time of muscle transposition significantly increases the rate of postoperative complications.

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.

At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Smooth Muscle Contraction
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...
