Anesthesia Department at AS Medical Complex

Safe, Comprehensive Anesthesia & Perioperative Care

The Anesthesia Department at AS Medical Complex provides comprehensive anesthesia and perioperative care for patients undergoing surgical, diagnostic, and selected medical procedures.

Anesthesia care extends beyond administering medicines during an operation. Anesthesiologists are involved in evaluating patients before surgery, developing an individualized anesthesia plan, monitoring vital body functions throughout the procedure, managing pain, and supporting safe recovery after anesthesia.

Our approach focuses on patient safety, comfort, careful monitoring, effective pain management, and coordinated perioperative care according to the patient's medical condition and the procedure being performed.

Pre-Anesthesia Evaluation

Before anesthesia, the anesthesiologist performs an assessment to understand the patient's overall health and identify factors that may influence anesthesia or surgery.

Professional anesthesia standards include review of the patient's medical history, previous anesthesia experiences, current medical therapy, relevant physical condition, and appropriate investigations before developing an anesthesia plan.

The assessment may include:

• Current medical conditions

• Previous surgeries

• Previous anesthesia experiences

• Current medications

• Medication allergies

• Previous drug reactions

• Heart disease

• High blood pressure

• Diabetes

• Lung disease

• Kidney disease

• Neurological conditions

• Sleep apnea

• Smoking history

• Alcohol or substance use where relevant

• Pregnancy status where applicable

• Relevant laboratory and diagnostic reports

Patients should provide complete and accurate medical information so the anesthesia team can plan care appropriately.

Individualized Anesthesia Planning

There is no single anesthesia technique suitable for every patient or every procedure.

The anesthesiologist considers factors such as:

• Type of surgery

• Duration of procedure

• Patient age

• Overall medical condition

• Heart and lung health

• Kidney and liver function

• Current medications

• Previous anesthesia history

• Risk of bleeding

• Expected postoperative pain

• Surgical position

• Patient-specific risks

The anesthesia plan may involve general anesthesia, regional anesthesia, sedation, or another appropriate technique.

The anesthesiologist discusses the planned approach and relevant risks with the patient before the procedure whenever circumstances allow.

General Anesthesia

General anesthesia produces a controlled state of unconsciousness during which the patient does not remain aware of the surgical procedure.

General anesthesia may be required for many major surgical procedures.

During general anesthesia, the anesthesia team continuously manages and monitors important body functions, including:

• Breathing

• Oxygen levels

• Heart rate

• Heart rhythm

• Blood pressure

• Circulation

• Temperature

• Anesthetic depth

• Fluid requirements

Professional anesthesia standards require continuous attention to important physiological functions throughout anesthesia.

Depending on the procedure, airway-management devices and mechanical ventilation may be required to support breathing.

Regional Anesthesia

Regional anesthesia blocks sensation in a larger region of the body while the patient may remain awake or receive sedation.

Regional anesthesia may be appropriate for selected procedures involving areas such as:

• Arms

• Legs

• Lower abdomen

• Pelvic region

• Other selected body regions

Regional techniques may include:

• Spinal anesthesia

• Epidural anesthesia

• Peripheral nerve blocks

• Other region-specific anesthesia techniques

Regional anesthesia can sometimes be used alone or combined with general anesthesia depending on the procedure and patient's condition.

The anesthesiologist determines whether regional anesthesia is suitable after reviewing clinical factors and potential risks.

Spinal Anesthesia

Spinal anesthesia involves administering anesthetic medicine into the lower back to temporarily block sensation in the lower part of the body.

It may be used for selected:

• Lower-limb procedures

• Urological procedures

• Gynecological procedures

• Obstetric procedures

• Other surgeries below the waist

The patient may remain awake or receive sedation depending on the clinical situation.

During spinal anesthesia, blood pressure, oxygen levels, heart rate, and other important parameters continue to be monitored.

Epidural Anesthesia & Analgesia

Epidural anesthesia involves placing medication near nerves in the spinal region through an epidural space.

It may be used for:

• Labor pain relief

• Selected surgical procedures

• Postoperative pain management

• Other clinically appropriate situations

An epidural catheter may allow medication to be administered continuously or at intervals.

The anesthesia team monitors the patient's response and adjusts treatment according to clinical requirements.

Obstetric Anesthesia

The Anesthesia Department provides anesthesia and pain-management support for women undergoing obstetric procedures.

Services may include:

• Labor analgesia where available

• Epidural pain relief

• Spinal anesthesia

• Anesthesia for Cesarean section

• General anesthesia when medically required

• Anesthesia support for emergency obstetric procedures

• Postoperative pain management

The anesthesia plan considers both maternal health and the clinical circumstances surrounding delivery.

Care is coordinated with the Gynecology & Obstetrics Department and other relevant teams.

Anesthesia for Cesarean Section

Spinal or other regional anesthesia techniques are commonly considered for Cesarean delivery when clinically appropriate.

Regional anesthesia allows the lower part of the body to be anesthetized while the mother generally remains conscious.

General anesthesia may be required in selected situations, including certain emergencies or when regional anesthesia is unsuitable.

The anesthesiologist evaluates factors such as:

• Maternal medical condition

• Urgency of delivery

• Previous anesthesia history

• Blood-clotting status

• Obstetric condition

• Fetal and maternal circumstances

The safest appropriate anesthesia technique is selected for the individual situation.

Pediatric Anesthesia

Children require anesthesia care adapted to their age, size, stage of development, medical condition, and type of procedure.

Pediatric anesthesia may be provided for:

• General surgical procedures

• ENT surgery

• Orthopedic procedures

• Urological procedures

• Diagnostic procedures requiring anesthesia

• Emergency procedures

• Other pediatric operations

Before anesthesia, parents or caregivers should inform the team about:

• Previous surgeries

• Previous anesthesia reactions

• Current medicines

• Allergies

• Recent respiratory illness

• Asthma

• Heart conditions

• Other medical problems

Children and infants can have different anesthesia-related considerations from adults, making appropriate preoperative assessment particularly important.

Anesthesia for Older Adults

Older adults may have increased anesthesia-related risks because of age-related changes and associated conditions such as:

• High blood pressure

• Heart disease

• Diabetes

• Kidney disease

• Lung disease

• Neurological disorders

• Multiple medications

• Frailty

The anesthesia team considers these factors when selecting medicines, monitoring requirements, and postoperative recovery plans.

Older adults may also be at increased risk of temporary confusion or other postoperative cognitive problems after major procedures, which may require additional monitoring.

Anesthesia for Patients With Heart Disease

Patients with cardiovascular conditions may require additional assessment before surgery.

Relevant conditions may include:

• Coronary artery disease

• Previous heart attack

• Heart failure

• Heart valve disease

• Arrhythmias

• High blood pressure

• Previous cardiac surgery

• Other cardiovascular diseases

Depending on the planned operation and patient's condition, additional evaluation may involve:

• ECG

• Echocardiography

• Blood tests

• Cardiology consultation

• Medication review

• Other cardiac investigations

Anesthesia and Cardiology teams may coordinate care when appropriate.

Anesthesia for Patients With Lung Disease

Respiratory conditions can influence anesthesia planning and postoperative recovery.

Patients should inform the anesthesiologist if they have:

• Asthma

• COPD

• Chronic bronchitis

• Previous severe pneumonia

• Sleep apnea

• Pulmonary fibrosis

• Other chronic lung diseases

• Current respiratory infection

• Smoking history

Anesthesia can affect breathing, so underlying respiratory conditions may require additional planning and monitoring.

Some patients may require Pulmonology assessment before major elective surgery.

Diabetes & Anesthesia

Patients with diabetes require appropriate perioperative planning because fasting, surgery, anesthesia, and changes in normal eating patterns can affect blood glucose.

The anesthesia and surgical teams may review:

• Diabetes type

• Blood glucose control

• Insulin treatment

• Oral diabetes medicines

• Recent blood glucose levels

• HbA1c when relevant

• Kidney function

• Diabetes-related complications

Patients should follow specific instructions provided by their medical team regarding diabetes medicines and fasting before surgery rather than changing medication independently.

Kidney Disease & Anesthesia

Kidney function can influence:

• Selection of medicines

• Medication doses

• Fluid management

• Electrolyte balance

• Postoperative monitoring

Patients with chronic kidney disease, dialysis requirements, or abnormal kidney function may require additional assessment and coordinated care with Nephrology before or after surgery.

Sleep Apnea & Anesthesia

Patients with Obstructive Sleep Apnea (OSA) should inform their anesthesia team before surgery.

Sleep apnea can increase the risk of breathing-related problems during and after anesthesia, particularly when sedative or pain medicines are used.

Patients should mention:

• Diagnosed sleep apnea

• Loud snoring

• Witnessed pauses in breathing during sleep

• CPAP use

• Daytime sleepiness

• Previous anesthesia-related breathing problems

Additional postoperative monitoring may be required depending on the procedure and severity of sleep apnea.

Airway Management

Maintaining a safe airway and adequate breathing is an important part of anesthesia care.

Depending on the procedure and anesthesia technique, airway management may involve:

• Face-mask ventilation

• Supraglottic airway devices

• Endotracheal intubation

• Mechanical ventilation

• Oxygen supplementation

• Other airway-management techniques

The anesthesiologist assesses factors that may make airway management more complex and prepares an appropriate plan.

Patients should inform the team about previous difficult intubation or anesthesia-related airway problems.

Intraoperative Monitoring

Continuous monitoring is a central component of anesthesia safety.

Depending on the type of procedure, monitoring may include:

• Heart rate

• Heart rhythm

• Blood pressure

• Oxygen saturation

• Breathing

• Carbon dioxide levels

• Body temperature

• Fluid balance

• Urine output in selected procedures

• Other specialized monitoring

ASA standards emphasize continuous evaluation of oxygenation, ventilation, circulation, and other important physiological functions during anesthesia.

Additional invasive or advanced monitoring may be required for complex or high-risk operations.

Blood & Fluid Management

During surgery, patients may require careful management of:

• Intravenous fluids

• Blood loss

• Electrolytes

• Blood products

• Circulatory status

The anesthesia team works closely with the surgical team to maintain appropriate circulation and respond to changes during the procedure.

Blood transfusion is used only when clinically indicated according to the patient's condition, blood loss, laboratory results, and surgical circumstances.

Sedation

Some diagnostic or therapeutic procedures do not require full general anesthesia but may require sedation.

Sedation can help:

• Reduce anxiety

• Improve comfort

• Reduce awareness of selected procedures

• Allow procedures to be completed safely

The depth of sedation can vary from minimal sedation to deeper levels.

Because patients can respond differently to sedative medicines, appropriate monitoring and airway-management capability are important whenever moderate or deep sedation is provided.

Monitored Anesthesia Care

Monitored Anesthesia Care (MAC) involves anesthesia-team supervision during selected procedures where sedation, pain control, and close physiological monitoring may be required.

Depending on the procedure, the patient may remain responsive or become more deeply sedated.

The anesthesia professional remains prepared to adjust the depth of sedation and support breathing or circulation when required.

Emergency Anesthesia

Emergency surgery can present additional challenges because there may be limited time for preparation and the patient may already be medically unstable.

Emergency anesthesia care may be required for:

• Trauma

• Acute abdominal emergencies

• Emergency obstetric surgery

• Severe infection requiring surgery

• Acute bleeding

• Emergency orthopedic procedures

• Other urgent operations

The anesthesia team rapidly evaluates:

• Airway

• Breathing

• Circulation

• Medical history where available

• Allergies

• Current medications

• Recent food or fluid intake

• Laboratory results

• Surgical urgency

Care is coordinated with the Emergency, Surgery, Critical Care, and other relevant teams.

High-Risk Surgical Patients

Some patients require more detailed planning because their medical conditions increase perioperative risk.

Factors that may increase anesthesia risk include:

• Significant heart disease

• Severe lung disease

• Kidney disease

• Obesity

• Sleep apnea

• Diabetes

• Previous stroke

• Neurological disease

• Previous serious anesthesia reaction

• Advanced age

• Multiple chronic conditions

ASA patient guidance similarly identifies cardiovascular, respiratory, kidney, neurological, metabolic, and other health problems as factors that can influence anesthesia risk.

High-risk patients may require multidisciplinary review before surgery.

Post-Anesthesia Recovery

After anesthesia, patients are monitored while they recover from the effects of anesthetic medicines.

Recovery monitoring may include:

• Level of consciousness

• Breathing

• Oxygen saturation

• Blood pressure

• Heart rate

• Pain

• Nausea or vomiting

• Surgical bleeding

• Other postoperative concerns

Anesthesia care continues into the recovery period rather than ending immediately when surgery is completed.

Patients are transferred from the recovery area when they meet appropriate clinical criteria.

Postoperative Pain Management

Effective pain management is an important part of recovery after surgery.

Depending on the procedure and patient, pain management may involve:

• Oral pain medicines

• Intravenous medication

• Patient-controlled analgesia where appropriate

• Epidural analgesia

• Regional nerve blocks

• Local anesthetic techniques

• Multimodal pain-management strategies

The aim is to control pain sufficiently to support:

• Comfortable breathing

• Movement

• Physiotherapy

• Sleep

• Early mobilization

• Overall recovery

Pain treatment is individualized according to the operation and patient's medical condition.

Nausea & Vomiting After Anesthesia

Some patients experience nausea or vomiting after anesthesia.

Risk may vary according to:

• Type of surgery

• Type of anesthesia

• Previous history of postoperative nausea

• Individual susceptibility

• Pain medications

• Other clinical factors

The anesthesia team may use medicines or other strategies to reduce or treat postoperative nausea when appropriate.

Patients should inform the anesthesiologist if they have experienced severe nausea or vomiting following previous anesthesia.

Common Temporary Effects After General Anesthesia

Temporary effects following general anesthesia may include:

• Drowsiness

• Nausea

• Vomiting

• Chills

• Sore throat

• Dry mouth

• Temporary confusion

• Dizziness

Most common side effects are temporary, although serious complications can occur rarely.

Patients should report significant or worsening symptoms to the treating medical team.

Anesthesia Risks

No medical procedure is completely without risk.

The likelihood of an anesthesia-related complication depends on:

• Patient health

• Age

• Type of anesthesia

• Type and duration of surgery

• Emergency versus planned procedure

• Existing medical conditions

• Individual risk factors

Potential complications can range from relatively minor temporary side effects to rare serious problems involving breathing, circulation, allergic reactions, neurological effects, or other systems.

The anesthesiologist assesses individual risks and takes appropriate precautions to reduce them.

Previous Anesthesia Reactions

Patients should always tell their anesthesiologist if they or a close family member have experienced:

• Severe allergic reaction during anesthesia

• Difficult intubation

• Unexplained serious complication

• Malignant hyperthermia

• Prolonged difficulty waking

• Severe postoperative nausea

• Other unusual anesthesia problems

A personal or family history of malignant hyperthermia is particularly important because it can represent a rare inherited serious reaction to certain anesthetic medicines.

Fasting Before Anesthesia

Patients are usually given specific instructions about when to stop eating and drinking before anesthesia.

Fasting is important because anesthesia can affect normal protective reflexes and may increase the risk of stomach contents entering the lungs.

The exact instructions depend on:

• Patient age

• Procedure

• Type of anesthesia

• Medical condition

• Medications

• Urgency of surgery

Patients should follow the instructions provided by their anesthesia and surgical teams rather than using general internet guidance for their individual procedure.

If fasting instructions are accidentally broken, tell the anesthesia team rather than hiding the information.

Medications Before Surgery

Some regular medicines may be continued before surgery, while others may need temporary adjustment.

Examples requiring individualized instructions may include:

• Blood thinners

• Diabetes medicines

• Insulin

• Blood-pressure medicines

• Heart medicines

• Steroids

• Psychiatric medicines

• Seizure medicines

• Weight-management or diabetes injections

• Herbal products or supplements

Patients should provide a complete medication list during pre-anesthesia assessment.

Do not independently stop an important medicine unless instructed by the treating medical team.

Smoking & Anesthesia

Smoking can increase respiratory and other perioperative risks. ASA patient guidance identifies smoking as a factor that can raise the risk of anesthesia-related complications.

Patients undergoing planned surgery are encouraged to discuss smoking cessation with their healthcare team.

Even reducing or stopping smoking before surgery can form part of overall perioperative risk reduction, although recommendations should be individualized.

Anesthesia & Pregnancy

Women who are pregnant or may be pregnant should inform the anesthesia and surgical teams before elective procedures.

The anesthesia plan considers:

• Stage of pregnancy

• Urgency of procedure

• Maternal health

• Type of surgery

• Obstetric considerations

• Potential medication effects

Necessary emergency surgery should not automatically be delayed because of pregnancy, but appropriate multidisciplinary planning may be required.

Critical Care Support

Anesthesiologists have expertise in airway management, ventilation, circulation, resuscitation, and management of critically ill surgical patients.

Depending on hospital structure and available services, anesthesia specialists may contribute to:

• Critical-care stabilization

• Airway management

• Mechanical ventilation

• Emergency resuscitation

• Postoperative intensive care

• Management of unstable surgical patients

Anesthesiology is closely linked to perioperative and critical-care medicine.

Coordinated Surgical Care

Anesthesia works closely with almost every surgical and procedural specialty.

Depending on the patient's procedure, the Anesthesia Department may coordinate with:

• General Surgery

• Orthopedics

• Gynecology & Obstetrics

• Urology

• ENT

• Neurosurgery

• Pediatric Surgery

• Cardiology

• Cardiac Surgery

• Gastroenterology

• Radiology

• Emergency Medicine

• Critical Care

• Other relevant departments

This multidisciplinary coordination helps ensure that the anesthesia plan is consistent with the surgical procedure and patient's overall medical condition.
