Anesthesiologist: pain relief and resuscitation

An anesthesiologist is a physician responsible for patient safety at all stages of the perioperative care pathway: preoperative assessment, selection and administration of analgesia and sedation, monitoring of respiration and circulation during surgery, and ensuring comfort and safety after surgery. Their work encompasses emergency and elective procedures, obstetric and pediatric anesthesiology, intensive care, and palliative care. The modern role of an anesthesiologist extends far beyond administering anesthesia: they are perioperative specialists in minimizing risks and accelerating recovery. [1]

An anesthesiologist plans a pain management strategy individually based on the patient's condition, the type of surgery, and recovery goals. The physician coordinates resuscitation and pain management teams, implements monitoring methods, and provides assistance during unplanned crises. Skills include airway management, hemodynamics, transfusion management, and the administration of pain medications, taking into account potential side effects. [2]

The profession requires constant updating of knowledge: new guidelines on preoperative preparation, difficult airway management, opioid burden reduction strategies, and enhanced recovery protocols are becoming standard practice. Working with operating room safety systems, including surgical checklists and equipment assessments, is also important. [3]

The anesthesiologist not only provides the patient with anesthesia but also provides a risk mitigation plan: preoperative chronic disease management, medication and nutrition recommendations, a postoperative pain management strategy, and safe discharge criteria. This improves outcomes and reduces complications. [4]

When is an anesthesiologist consultation scheduled?

An anesthesiologist consultation is recommended in advance of planned surgeries to assess risk and prepare for the procedure. Urgent consultation is necessary in unstable patients, suspected of having a difficult airway, or significant comorbidities such as cardiac failure, chronic obstructive pulmonary disease, severe renal failure, complicated diabetes, coagulation disorders, and high body weight. [5]

For newborns and children, consultation with an anesthesiologist is mandatory for all interventions, including planned preparation and selection of sedation protocols. Pregnant women require separate assessment in cases of childbirth under anesthesia or surgical interventions during pregnancy. Particular attention is paid to patients with obstructive sleep apnea. [6]

If the patient has previous anesthesia complications or a family history of malignant hyperthermia, a detailed genetic and anesthesiological evaluation is required prior to elective surgery. Consultation is also necessary if taking anticoagulants or anticipating regional anesthesia. [7]

Before emergency procedures, the anesthesiologist participates in a rapid assessment algorithm and in joint risk-taking with the surgeon and patient or relatives, if possible. This reduces the likelihood of unexpected events during the intraoperative period. [8]

Table 1. General indications for consultation with an anesthesiologist

Indication	Why is it important?
Chronic heart and lung diseases	Risk assessment and pain management strategy
Obesity, sleep apnea	Risk of difficult airway and complications
Taking anticoagulants	Planning regional techniques and bleeding
Previous complications of anesthesia	Finding the causes and adjusting the technique
Pregnancy	Choosing a safe approach for mother and fetus

Preoperative assessment: what does the anesthesiologist check?

The assessment includes a medical history, a physical examination focusing on the respiratory tract, cardiovascular system, and renal function, and a review of current medications. Laboratory tests and imaging studies are performed as needed, including blood tests, coagulation profiles, electrocardiography, chest X-ray, and lung function assessment. All interventions are planned taking into account the risk of complications according to international guidelines. [9]

A special focus is placed on airway assessment: anthropometric characteristics, limitations of neck mobility, dental condition, presence of upper respiratory tract pathology, and history of difficult intubation. If difficult airway access is suspected, the anesthesiologist selects a strategy and equipment in advance. This reduces the time of forced ventilation and the risk of complications. [10]

The assessment also includes a review of the patient's medications: which medications should be continued, temporarily discontinued, or adjusted. Current recommendations for preoperative fluid intake and permitted beverages form the basis for optimal patient preparation. [11]

The result of the preoperative assessment is a clear management plan: the method of anesthesia, the need for invasive monitoring, the volume of perioperative infusion therapy, and the postoperative pain control regimen. The plan is communicated to the surgeon and patient and documented. [12]

Difficult Airway: Preparation and Algorithms

Difficult airway management remains one of the leading causes of anesthesia complications. Current guidelines recommend a step-by-step approach, pre-determined by the team, with backup resources: mask-laparyngeal ventilation, video laryngoscopes, intranasal and tracheal devices, and, if necessary, an emergency cricothyroidotomy plan. The principle is to prepare in advance and minimize the number of intubation attempts. [13]

A key element is teamwork and scenario testing using checklists. Having plans A, B, and C and a clear division of roles within the team increases the chances of successful problem solving and reduces the number of errors. Current recommendations emphasize the importance of training and simulations. [14]

If difficult airway access is anticipated, the option of awake intubation or regional anesthesia is discussed if surgery is feasible. This avoids emergency decisions and reduces the risk of airway injury. In the case of emergency difficult airway access, algorithms include immediate oxygenation and the use of available devices to maintain gas exchange. [15]

Saturation monitoring and timely assessment of ventilation effectiveness remain the cornerstone. The use of video laryngoscopes and modern devices often improves visualization during intubation and is recommended as part of the standard operating room kit. [16]

Anesthesia techniques: general, regional, sedation

General anesthesia provides complete control over the patient's breathing and consciousness. The choice of induction and maintenance medications is based on concomitant illnesses, the duration of the surgery, and the goal of rapid recovery. Individualization of doses based on body weight and organ function is important. [17]

Regional techniques—spinal and epidural anesthesia, paired nerve blocks—are used to reduce systemic burden and decrease the need for opioid analgesics. When performed correctly, regional anesthesia improves postoperative pain control and accelerates recovery. The decision to use a regional technique is made after assessing coagulation and risks. [18]

Sedation is used for diagnostic and minor surgical procedures. The anesthesiologist maintains the patient's consciousness at a level sufficient for safety and monitors respiration and hemodynamics. The principle is the minimum necessary depth of sedation with monitoring of the level of consciousness and oxygenation. [19]

A combined approach is often used: light general anesthesia combined with a regional block to improve postoperative pain control and reduce systemic side effects. The concept of multimodal anesthesia is becoming standard in enhanced recovery protocols. [20]

Table 3. Comparison of the main methods of anesthesia

Method	Advantages	Restrictions
General anesthesia	Full breathing control, possibility of long-term operations	Risk of nausea, longer wake-up time in some patients
Spinal anesthesia	Fast onset, good analgesia for the lower half of the body	Block level limitation, risk of hypotension
Epidural anesthesia	Long-term postoperative analgesia	Requires experience, risk of bleeding in coagulopathy
Peripheral nerve blocks	Local potent analgesia, opioid reduction	Ultrasound monitoring is necessary, risk of motor weakness

Preoperative fasting and fluids

Updated preoperative fasting guidelines allow healthy patients to drink clear carbohydrate-containing drinks up to 2 hours before induction and light foods up to 6 hours before. This recommendation reduces hunger and stress while not increasing the risk of aspiration under standard conditions. However, for patients with an increased risk of aspiration, longer fasting periods should be discussed individually. [21]

Intravenous fluid management during surgery is optimized to prevent both hypovolemia and fluid overload. Enhanced recovery programs (ERPs) favor targeted therapy based on dynamic volume targets to reduce the risk of postoperative edema and respiratory complications. [22]

Continuation of routine medications, such as cardiac medications, is usually discussed with the anesthesiologist. Anticoagulants and antiplatelet agents require special consideration due to the risk of bleeding with regional techniques. Instructions for discontinuing medications should be provided in advance. [23]

Preoperative hydration with a carbohydrate drink before surgery improves metabolic response, and some programs consider such drinks as an element of preoperative optimization. The decision to use such drinks should take into account the type of surgery and comorbidities. [24]

Pain control and opioid reduction strategies

Multimodal analgesia is a combination of several mechanisms for pain control and opioid burden reduction. It includes non-functional analgesics, non-steroidal anti-inflammatory drugs, paracetamol, regional blocks, local infiltrations, and, if indicated, amantadine or gabapentin. This strategy reduces the risk of nausea, delayed recovery, and addiction. [25]

Regular pain assessment and early mobilization, along with adequate analgesia, accelerate recovery and reduce the length of hospital stay. The postoperative pain management plan is discussed in advance and adjusted accordingly. Reducing opioid use also reduces the risk of constipation and respiratory depression. [26]

For some procedures, long-term catheters are used for continuous regional analgesia, which allows for a reduction in systemic therapy and improved pain control in the early postoperative period. The decision to use such methods depends on the type of surgery and the availability of specialists. [27]

The implementation of opioid reduction protocols requires interdisciplinary coordination with surgeons and the rehabilitation department. Patients are provided with an explanation of the plan and side effects, which improves adherence and safety. [28]

Table 4. Examples of components of multimodal analgesia

Component	Target	Note
Paracetamol	Basic non-narcotic analgesic	Prescribed regularly
NSAIDs	Anti-inflammatory effect	Assess the risk of bleeding and kidney damage
Regional block	Local pain control	Reduces systemic opioids
Local infiltration	Additional local effect	Often used in minimally invasive surgeries
Oral adjuvants	Gabapentinoids for neuropathy	Choose with care

Accelerated recovery protocols and security

Enhanced postoperative recovery programs rely on coordinated efforts between the surgeon and anesthesiologist: minimally invasive access, controlled infusion volumes, multimodal analgesia, early nutrition, and mobilization. The anesthesiology component in such protocols is critical to reducing complications and the patient's rapid return to normal activity. [29]

A surgical and anesthesiology safety checklist is used in the operating room. The World Health Organization developed a surgical checklist that has been shown to reduce mortality and complications and includes elements related to anesthesia and equipment. Routine use of checklists and pulse oximetry improves outcomes, especially in resource-limited settings. [30]

The anesthesiologist monitors postoperative respiratory status, oxygen saturation, pain, nausea, urine output, and conscious function. The decision to transfer to the intensive care unit or to a regular ward is based on stability and the complexity of the procedure. Early discharge protocols reduce readmissions. [31]

Regular staff training and emergency scenario drills, including difficult airway and circulatory arrest exercises, remain key safety factors. Having algorithms and accessible equipment saves lives in critical moments. [32]

Table 5. Elements of the ERAS anesthesia protocol

Element	Practical measure
Preoperative optimization	Carbohydrate drink, smoking cessation, anemia correction
Intraoperative tactics	Minimally invasive access, targeted infusion therapy
Anesthesia	Multimodal scheme, regional blocks
Postoperative care	Early mobilization and nutrition, pain control

Practical recommendations for the patient

1. Attend your preoperative consultation with a complete list of medications, allergies, and previous anesthesia procedures. This will speed up and facilitate risk assessment. [33]
2. Follow preoperative fasting and permitted beverage instructions. For chronic conditions, discuss medication regimen with your anesthesiologist. [34]
3. Tell your doctor about breathing problems, snoring, previous complications from anesthesia, and a family history of malignant hyperthermia. These findings change the safety plan. [35]
4. Ask your doctor about the post-operative plan: how pain will be managed and when you can expect to return home. Understanding the scenario reduces anxiety and improves recovery. [36]
