What are the key points of preoperative and postoperative care for laparoscopic surgical instruments?

The key points of preoperative and postoperative care for laparoscopic surgical instruments are as follows:

Key points of preoperative care

Systemic examination: Conduct a comprehensive physical examination, including vaginal secretions, cervical smear examination, electrocardiogram, chest X-ray, etc., to exclude cardiovascular system diseases and abnormal liver and kidney function.

Intestinal preparation: Fasting and waterlessness for 12 hours before surgery, and gastrointestinal decompression if necessary. Start a semi-liquid diet the night before surgery, and fasting and waterlessness from 10 o'clock the night before surgery until before surgery.

Skin cleaning: Routine skin preparation is performed 1 day before surgery, with special attention to the cleaning of the umbilicus, which can be scrubbed with soapy cotton balls or turpentine and ethanol.

Psychological preparation: Conduct psychological assessments on patients to understand their emotional states such as anxiety, fear and depression, and provide appropriate psychological counseling.

Quit smoking: If you have the habit of smoking, quit smoking 2 weeks before surgery, and perform lung function exercises such as deep breathing and blowing balloons.

Key points of postoperative care

Vital sign monitoring: ECG monitoring is used to closely monitor the patient's vital signs after surgery. If any abnormality is found, it should be handled in time.

Posture adjustment: The patient should lie flat without a pillow and let the patient's head tilt to one side to prevent oral secretions or vomit from flowing into the trachea and causing suffocation.

Wound care: Strengthen wound care, change dressings in time, pay attention to whether there is local redness, swelling, exudation, etc., and deal with it in time.

Drainage tube management: Observe the status of the abdominal drainage tube. If there is blockage, flush the tube in time to keep it unobstructed.

Diet management: A small amount of liquid food can be taken within 24 hours after surgery, and gradually transition to a normal diet, mainly a high-protein diet.

Rest and activity: Rest for 2-4 weeks after surgery, try to avoid strenuous activities, and maintain adequate rest.

Bathing and daily life: You can take a bath three days after surgery, but the wound needs to be kept dry.

Through the above pre- and post-operative care measures, the surgical risk can be effectively reduced and the patient's rapid recovery can be promoted.

What are the specific items and standards for the systemic examination before laparoscopic surgery?

The specific items and standards of the systemic examination before laparoscopic surgery are as follows:

Routine blood examination: including white blood cell count, red blood cell count, hemoglobin concentration, platelet count, etc.

Liver and kidney function examination: mainly including liver function indicators (such as ALT, AST, total cholesterol), kidney function indicators (such as blood creatinine, urea nitrogen).

Coagulation system examination: including bleeding time, coagulation time, prothrombin time, etc.

Blood type examination: to ensure blood type matching during blood transfusion.

Eight virus examinations: including hepatitis B surface antigen, hepatitis C surface antigen, etc.

Electrocardiogram examination: to evaluate heart function and exclude heart disease.

Chest X-ray and abdominal plain film: to understand the condition of the lungs and abdomen, and to exclude diseases such as tuberculosis and pneumonia.

Imaging examination: such as B-ultrasound, CT, MRI, etc., to understand the size, range and location of the lesion.

Other related examinations: depending on the type of surgery and the patient's condition, special examinations such as colonoscopy and gastroscopy may also be required.

In addition, for specific types of surgery, such as laparoscopic hysterectomy, special examinations such as gynecological B-ultrasound are also required.

The scientific basis of preoperative fasting and water abstinence and its impact on patient recovery.

The scientific basis of preoperative fasting and water abstinence and its impact on patient recovery can be analyzed in detail from multiple aspects.

Scientific basis

Preoperative fasting is mainly to avoid the risk of vomiting and aspiration under anesthesia. When a person is under anesthesia, the esophageal sphincter relaxes, and the gastric contents are easily refluxed into the airway, causing vomiting or aspiration. Therefore, preoperative fasting can reduce these risks.

Studies have shown that fasting 2 hours before surgery and giving pure liquids orally can reduce patients' hunger and anxiety, promote postoperative intestinal peristalsis recovery, and facilitate postoperative recovery.

Long-term fasting and water abstinence can cause patients to experience discomfort such as thirst, hunger, dizziness, irritability, and even cause stress reactions such as collapse, hypoglycemia, and insulin resistance, which will have an adverse effect on postoperative recovery.

Specific time arrangement for fasting and drinking before surgery
According to the Chinese Clinical Practice Guidelines for Accelerated Recovery Surgery released in 2023, the time for fasting and drinking before surgery generally follows the "2-4-6-8" principle, namely:
No water for 2 hours before surgery;
Breastfeeding can be given to infants 4 hours before surgery;
No solid starchy food for 6 hours;
No fat solid food for 8 hours.
This time arrangement is designed to balance preoperative safety and patient comfort to ensure safety during and after surgery.

Effect on patient recovery
Drinking carbohydrate clear drinks before surgery can reduce postoperative insulin resistance, reduce catabolism, and promote rapid recovery. In addition, clinical evidence shows that drinking carbohydrates before surgery can increase patient compliance and reduce postoperative nausea and vomiting, and reduce the occurrence of adverse complications.

Short-term fasting and drinking (such as 2 hours of water fasting) will not increase the risk of gastric reflux and suffocation during surgery, but can reduce the patient's hunger and nervous anxiety, promote postoperative intestinal peristalsis recovery, and facilitate postoperative recovery.

Long-term fasting and water abstinence (such as 12 hours of fasting) will make patients feel thirsty, hungry, dizzy, irritable and other discomforts, and the body will also experience stress reactions such as collapse, hypoglycemia, and insulin resistance, which will have an adverse effect on postoperative recovery.

The scientific basis for preoperative fasting and water abstinence is mainly to avoid the risk of vomiting and aspiration during anesthesia, while reducing the patient's hunger and tension and anxiety, and promoting postoperative intestinal peristalsis recovery.

How to effectively manage abdominal drainage tubes to prevent infection?

The key measures for effective management of abdominal drainage tubes to prevent infection include the following aspects:

Fix and mark the drainage tube: fix the drainage tube with tape in an "S" shape to prevent slippage, and clearly mark the location of the drainage tube for easy observation and management.

Keep drainage unobstructed: squeeze the drainage tube regularly to ensure that the drainage fluid can flow out smoothly to prevent drainage fluid accumulation and infection. At the same time, keep the drainage bag below the incision plane to facilitate the natural flow of drainage fluid.

Observe changes in drainage fluid: regularly evaluate the amount, color and properties of drainage fluid. If the amount of drainage fluid increases significantly or the color is abnormal (such as blood red), the doctor should be notified in time for emergency treatment.

Aseptic operation: When changing the drainage bag or dressing, aseptic operation must be strictly performed to prevent bacterial contamination and infection.

Maintain an effective position: The patient should maintain an effective position after surgery, that is, the drainage tube should be lower than the mid-axillary line when lying flat, and should not be higher than the abdominal drainage port when standing or moving to prevent the drainage fluid from flowing back.

Check the wound regularly: Observe whether there is exudate at the wound dressing and deal with possible signs of infection in time.

Use negative pressure suction technology: For certain types of incisions, negative pressure closed drainage (VSD) technology can be used. This method uses the principle of negative pressure to fully drain the extraperitoneal wound bleeding, exudate and purulent secretions, reduce exudate accumulation, and thus achieve the effect of preventing wound infection.

Remove the drainage tube in time: Select a drainage tube of appropriate model and material according to the condition, and remove the drainage tube in time after the infection is cured to reduce the risk of infection.

In postoperative wound care, how to judge whether the dressing needs to be replaced and what is the standard for replacement?

In postoperative wound care, the criteria for judging whether the dressing needs to be changed and the criteria for changing it mainly include the following aspects:

Change frequency:

Generally, the dressing should be changed for the first time 24-48 hours after surgery, and then every 2-3 days. For surgical incisions without infection, the dressing can be changed every 2-3 days.
Special parts such as breast surgery wounds are changed every 3-5 days; skin grafting wounds are usually changed every 7-9 days.

Secretion and exudate:

If the wound has more secretions or exudate, the dressing may need to be changed every day or every two days. For patients with incision fat liquefaction, the dressing may need to be changed several times a day, up to 2-3 times.

Signs of infection:

If the wound shows signs of infection such as redness, swelling, pus, etc., it is recommended to change the dressing every day to deal with the infection in time and keep the wound clean.

Dressing status:

When changing the dressing, first check whether the old dressing is dry and clean. If the dressing oozes blood or exudates, it should be changed immediately.
If the dressing used is adhered to the wound, it must also be considered to change the dressing at the next dressing change.

Aseptic operation:

When changing the surgical wound dressing, it is necessary to comply with the aseptic operation standards and change the dressing according to the standard process to prevent surgical incision infection.
The criteria for judging whether the dressing needs to be changed in postoperative wound care are mainly based on the secretions of the wound, whether there are signs of infection, and the state of the dressing.

In postoperative dietary management, specific recommendations and possible discomfort reactions for high-protein diets.
In postoperative dietary management, specific recommendations and possible discomfort reactions for high-protein diets are as follows:

Specific recommendations for high-protein diets

Daily protein intake:

According to body weight, about 2 grams of protein are consumed per kilogram of body weight. For example, a 60-kilogram population can consume 120 grams of protein per day.
Another way to calculate is to multiply the body weight (kilograms) by 1.2-1.6 grams.

Protein source:

Emphasis on adequate intake of animal foods, such as eggs, milk, lean meat, etc., which are rich in high-quality protein.
Fish, chicken, and shrimp have a higher protein content, which is better than red meat.
High-protein foods also include tofu, chicken breast, salmon, cheese and cheese.

Diet structure:

Postoperative diet should be light, easy to digest, high in protein, high in calories, high in vitamins, and low in fat, from less to more, from thin to thick, eat less and more meals, and combine meat and vegetables.

Notes:

When choosing a high-protein diet, you should pay attention to the intake of high-quality protein and properly control the intake of fat. Do not choose a large amount of red meat and greasy food.

Possible discomfort reactions

Renal function burden:

Excessive protein intake may burden renal function and cause renal abnormalities.

Bone calcium loss:

A high-protein diet may cause bone calcium loss because protein metabolism requires a large amount of calcium.

Intestinal bacteria balance problem:

A high-protein diet may disrupt the balance of intestinal flora and affect intestinal health.

Cardiovascular risk:

Excessive intake of saturated fat and sodium may increase the risk of cardiovascular disease, and these substances are often consumed at the same time as high-protein foods.

Other discomfort reactions:

Some people may experience bloating, nausea or other digestive system symptoms on a high-protein diet, which is usually due to the body's adaptation process to high protein intake.
