Reserpine may affect anesthesia by increasing the risk of blood pressure fluctuations, enhancing the hypotensive effect of anesthetic agents, raising the likelihood of heart rate abnormalities, increasing the possibility of intraoperative bleeding, and affecting postoperative recovery. If surgery is required during treatment or if symptoms such as dizziness or palpitations occur, prompt medical consultation is recommended. Reserpine depletes catecholamines in the body, which may lead to a sudden drop in blood pressure during anesthesia.

From the perspective of core applications, 75% ethanol can destroy the protein structures of bacteria and viruses, and is used for skin disinfection prior to injections or punctures, as well as for cleaning medical instruments. As a solvent, it can dissolve medications to produce tinctures and lotions that are easily absorbed. It can also be used for physical cooling, helping to reduce fever by evaporative heat loss. However, if the concentration is too high, it may cause protein coagulation, forming a protective layer that reduces disinfection effectiveness.

If the face is injured, you may use mupirocin ointment, recombinant human epidermal growth factor gel, silicone gel, mucopolysaccharide polysulfate cream, or medical vaseline ointment as directed by a physician. Seek prompt medical attention if the wound is deep, bleeding persists, or signs of infection appear. Mupirocin ointment: an anti-inflammatory and antibacterial topical medication suitable for use in the early stages of wound healing.

Falls in the elderly may result from declining balance, impaired vision, osteoporosis, hypertension, Parkinson's disease, and other factors. These can be improved through enhanced balance training, vision correction, medication, nutritional supplementation, and other methods. If falls occur frequently or are accompanied by dizziness, limb weakness, or similar symptoms, prompt medical attention is necessary. With advancing age, older adults experience a decline in vestibular function and muscle strength.

The common pathophysiological changes in various types of shock generally include a sharp reduction in effective circulating blood volume, microcirculatory dysfunction, tissue and cellular hypoxia, metabolic disturbances, and multi-organ impairment. These changes interact with each other and progressively worsen the condition. Without timely intervention, they can become life-threatening. If early signs of shock such as sudden drop in blood pressure or altered consciousness occur, immediate medical attention is recommended.

Gallstone impaction refers to the condition in which gallstones move from the gallbladder into the cystic duct or neck of the gallbladder, becoming lodged and obstructing these narrow passages. This blockage prevents bile from draining properly, leading to gallbladder distension, inflammation, and a series of related symptoms. If sudden, severe pain in the upper right abdomen occurs and persists without relief, immediate medical attention is recommended.

The incisions for minimally invasive appendectomy are typically located in the abdomen, usually three in number—situated at the umbilicus and on both sides of the lower abdomen or near the midline of the lower abdomen. Each incision is small, generally 0.5–1 cm in length, and their exact positions may be slightly adjusted depending on the patient's condition. If redness, swelling, fluid discharge, or persistent pain occurs at the incision site after surgery, prompt medical attention is recommended.

Commonly used medications for scald burns include mupirocin ointment, moist burn ointment, recombinant human epidermal growth factor gel, ibuprofen tablets, and loratadine tablets. The wound should be cleaned before applying any medication, and the choice of drug should be made according to the severity of the burn and symptoms, following medical advice. Seek prompt medical attention if the burn covers a large area, is deep, or is accompanied by fever. Mupirocin ointment: suitable for superficial burns with risk of infection.

Commonly used measures for the effective treatment of tetanus generally include thorough wound debridement, administration of tetanus antitoxin, use of human tetanus immunoglobulin, application of antibiotics, and symptomatic and supportive therapies. It is necessary to remove necrotic tissue, foreign bodies, and contaminants from the wound, and repeatedly irrigate the wound with hydrogen peroxide solution or normal saline to disrupt the anaerobic environment required for the growth and reproduction of Clostridium tetani.

Core tests typically required when lymphoma is suspected may include lymph node ultrasound, lymph node biopsy with pathological examination, routine blood and biochemical tests, whole-body CT or PET-CT scans, and bone marrow aspiration. Ultrasound allows evaluation of the size, shape, margins, internal echogenicity, and blood flow of lymph nodes, helping to determine whether abnormal proliferation or structural changes are present.
