Introduction

In general, "inserting a urinary catheter" refers to the placement of a urinary catheter. Whether a urinary catheter is needed during general anesthesia depends primarily on the duration of the surgery and the patient's urinary function. A urinary catheter is usually required for longer surgical procedures. However, if the patient has normal urinary function and the surgery is brief, a catheter may not be necessary. If any discomfort occurs, seek medical attention promptly and receive appropriate symptomatic treatment under the guidance of a qualified physician.

In general, "inserting a urinary catheter" refers to the placement of a urinary catheter. Whether a urinary catheter is needed during general anesthesia depends primarily on the anticipated duration of the surgery. If the surgery is expected to be lengthy, a urinary catheter is usually required. However, if the surgery is brief, catheterization is typically unnecessary. If any discomfort occurs, patients should seek medical attention promptly and receive symptomatic treatment under the guidance of a qualified physician. The specific analysis is as follows:

If the surgery is expected to be long and the patient requires substantial intravenous fluid administration, a urinary catheter should be inserted. Prolonged surgical procedures and fluid infusion can lead to significant urine production; failure to drain urine timely may cause bladder distension and potential damage.

If the surgery is short and minimally invasive, the patient can empty the bladder before the procedure. Since only a small amount of urine is likely to accumulate during surgery, there is minimal risk of excessive bladder filling, making catheter insertion unnecessary.

Prior to undergoing general anesthesia, patients should have thorough communication with their doctors to understand the details of the surgery and follow medical advice in preparation, ensuring the procedure is conducted safely and smoothly.

The patient became confused after general anesthesia surgery.

After general anesthesia, a person may become confused, possibly due to factors such as anesthetic drugs, surgical trauma and inflammatory responses, or prolonged bed rest, which requires symptomatic treatment. Additionally, other conditions such as hypoglycemia, insufficient cerebral blood supply, or cerebral infarction could also be responsible. It is recommended that patients seek medical attention promptly if they experience any discomfort to avoid delays in treatment. In daily life, a light diet and adequate rest are also important.

Abdominal distension after general anesthesia surgery

In general, abdominal distension after general anesthesia is a common phenomenon, possibly caused by improper diet, indigestion, or accumulation of intestinal gas. Besides these common factors, it may also result from intestinal spasms, intestinal obstruction, hypokalemia, or other conditions. It is recommended to seek timely medical evaluation at a hospital to determine the underlying cause and receive appropriate treatment accordingly.

Is it not allowed to wear underwear during general anesthesia surgery?

Whether underwear can be worn during general anesthesia surgery depends on the specific circumstances. For surgeries involving the upper limbs or五官 (facial organs), especially those of lower surgical grade and short duration, wearing underwear is generally acceptable as long as it does not interfere with the proper functioning of anesthesia monitoring equipment. However, if the surgical site is located in the lower limbs, perineal area, or abdomen, patients are generally not allowed to wear underwear during general anesthesia surgery to avoid interfering with local disinfection and increasing the risk of infection.

What should the blood pressure be kept under during general anesthesia surgery?

For general anesthesia surgery, blood pressure should ideally be controlled at less than 140/90 mmHg, with diastolic pressure maintained between 60–90 mmHg. After surgery, vital signs—including heart rate, blood pressure, and respiratory rate—should generally be closely monitored. Following anesthesia and surgery, the body is typically weak, and proper positioning should be ensured during this period.

What are the dietary precautions after general anesthesia surgery?

Begin eating after bowel movements or flatus following abdominal surgery. For non-abdominal surgeries, eat once fully awake or 4 hours post-operation. After esophageal, intestinal, or gastro-intestinal anastomosis surgery, start with small amounts of water 2–3 days post-operation. Diet after abdominal surgery should primarily consist of liquids, gradually transitioning to semi-liquid foods. After non-abdominal surgery, focus on light and easily digestible foods. Following gastric or gastrointestinal surgery, resume a normal diet only after the wound has fully healed.

Can I still breastfeed after having general anesthesia during lactation?

Generally, breastfeeding is not recommended after undergoing general anesthesia surgery during lactation. The detailed analysis is as follows: General anesthesia may affect breastfeeding, so it is generally advised not to breastfeed after general anesthesia surgery while lactating. With general anesthesia, drugs enter the bloodstream and may potentially affect the infant's nervous system and respiratory system. Therefore, the choice of anesthetic agents is crucial.

Is it serious to drink a sip of water before general anesthesia surgery?

General anesthesia surgery generally refers to general anesthesia. Drinking even a small amount of water before general anesthesia can directly affect the surgical procedure, so it is quite serious. General anesthesia typically involves the use of sedatives and analgesics to reduce the patient's surgical pain. These medications can cause muscle relaxation and stimulate the gastrointestinal tract, potentially leading to vomiting. Under normal circumstances, patients must strictly abstain from food and drink prior to general anesthesia to prevent an increase in stomach contents.

What is neck intubation?

Neck intubation is generally suitable for situations such as general anesthesia surgery, neck trauma, and asthma. Specifically: if a patient requires procedures such as organ transplantation or craniotomy that necessitate general anesthesia, neck intubation should be chosen to maintain an open airway during the procedure, preventing respiratory complications and reducing the risk of brain injury.
