Nicotine replacement therapy is as effective as medications, such as bupropion, in helping people quit smoking for at least six months. All forms of nicotine replacement therapy, including nicotine gum, patches, nasal spray, inhalers, and lozenges, have similar success rates in terms of helping people stop smoking. However, the likelihood that someone will stick to a certain treatment varies, with compliance being the highest with nicotine patches, followed by nicotine gum, inhalers, and nasal sprays. Using a few different nicotine replacement methods in combination may improve success rates in stopping tobacco use. Additionally, using nicotine replacement with counseling has been proven to improve tobacco abstinence rates. These other strategies include: creating a plan to quit and utilizing quit programs, a quit phone line, or app that provides tips and inspiration to help quit.Using nicotine replacement therapy to quit smoking should be considered for people who are severely dependent on nicotine. People who are severely dependent include those who smoke: more than one pack per day, within five minutes of awakening, while ill, when they wake up in the middle of the night, to ease withdrawal signs and symptoms.Nicotine replacement products are most beneficial for heavy smokers who smoke more than 15 cigarettes per day. There are not enough studies to show whether NRT helps those who smoke fewer than 10 cigarettes per day. Effectiveness
Evaluation of NRT in real-world studies produces more modest outcomes than efficacy studies conducted by industry-funded trials.
Lower extremity superficial phlebitis is associated with conditions that increase the risk of thrombosis, including abnormalities of coagulation or fibrinolysis, endothelial dysfunction, infection, venous stasis, intravenous therapy and intravenous drug abuse. Diagnosis
Clinical evaluation is the primary diagnostic tool for thrombophlebitis. Patients with thrombophlebitis complain of pain along the affected area. Some report constitutional symptoms such as low grade fever and aches. On physical examination, the skin over the affected vein exhibits erythema, warmth, swelling, and tenderness. Later in the disease, as induration subsides, erythema gives way to a ruddy or bruised color.Duplex ultrasound identifies the presence, location and extent of venous thrombosis, and can help identify other pathology that may be a source of the patients complaints. Ultrasound is indicated if superficial phlebitis involves or extends into the proximal one-third of the medial thigh, there is evidence for clinical extension of phlebitis, lower extremity swelling is greater than would be expected from a superficial phlebitis alone or diagnosis of superficial thrombophlebitis in question. Treatment
Treatment with compression stockings should be offered to patients with lower extremity superficial phlebitis, if not contraindicated (e.g., peripheral artery disease). Patients may find them helpful for reducing swelling and pain once the acute inflammation subsides.
