Surgical Safety and Anesthesia Standards

Surgical Safety and Anesthesia Standards

Introduction

·        Surgery is a vital component of healthcare, often offering life-saving or life-enhancing interventions.

·        However, it is also inherently risky, with the potential for adverse events such as wrong-site surgeries, anesthesia complications, and preventable surgical errors. Globally, it is estimated that over 230 million major surgical procedures are performed annually, with a significant percentage resulting in avoidable harm due to safety lapses.

·        To address these risks, international standards—especially those set by the World Health Organization (WHO), Joint Commission International (JCI), and various national accreditation boards (e.g., NABH, AHRQ guidelines)—have established protocols to reduce errors and improve outcomes.

Wrong Site/Procedure/Patient Surgery

Definition

Also referred to as “Never Events,” wrong site, wrong procedure, and wrong patient surgeries are serious, preventable incidents in surgical care.

• Wrong Site Surgery: Performing surgery on the incorrect body part or side.
• Wrong Procedure Surgery: Performing an unintended or incorrect surgical intervention.
• Wrong Patient Surgery: Operating on the wrong patient due to identification errors.

Causes

• Inadequate patient identification
• Lack of proper communication during handovers
• Failure in preoperative verification and consent process
• Mislabeling of radiology or pathology results
• Absence of standardized site-marking protocols
• Pressure due to time constraints and workload

Consequences

• Permanent disability, morbidity, or mortality
• Loss of trust between patient and healthcare providers
• Legal implications, malpractice lawsuits
• Damaged institutional reputation

Prevention Strategies

1. Preoperative Verification:
• Confirm patient identity with two identifiers (name, DOB, hospital ID).
• Verify procedure and consent form.
2. Site Marking:
• Surgeon marks the surgical site with indelible ink in presence of the patient (when possible).
• Standardized symbols (e.g., “YES” at correct site).
3. Time-Out Procedure (Universal Protocol):
• Conducted immediately before incision.
• Involves the surgical team confirming patient, procedure, and site.
4. Team Communication:
• Standardized checklist discussion.
• Addressing any uncertainty before incision.

WHO Surgical Safety Checklist

Introduction

·        The WHO Surgical Safety Checklist (2008) is a 19-item tool designed to improve safety and reduce avoidable complications and deaths during surgery.

·        Studies have shown that implementation reduces perioperative complications by up to 36% and mortality by nearly 47%.

Structure of the Checklist

The checklist is divided into three critical phases of an operation:

1. Sign In (Before Induction of Anesthesia):
• Verify patient identity, procedure, and surgical site.
• Confirm consent obtained.
• Mark surgical site (if applicable).
• Check anesthesia safety (airway risk, allergies).
• Ensure availability of blood products and equipment.
2. Time Out (Before Skin Incision):
• Team members introduce themselves by name and role.
• Confirm patient, procedure, and site aloud.
• Anticipate critical steps, duration, and blood loss.
• Confirm prophylactic antibiotics given within 60 minutes before incision.
3. Sign Out (Before Patient Leaves Operating Room):
• Confirm procedure performed.
• Verify instrument, sponge, and needle counts.
• Label and secure specimens.
• Review recovery plan and potential complications.

Benefits

• Enhances communication among surgical team members.
• Ensures critical steps are not missed.
• Reduces preventable complications (infection, bleeding, retained foreign objects).
• Improves teamwork and patient safety culture.

Safe Anesthesia Practices

Importance

·        Anesthesia is essential for pain relief, muscle relaxation, and patient immobility during surgery, but carries risks such as airway compromise, allergic reactions, aspiration, and cardiovascular collapse.

·        Safe anesthesia standards are crucial to minimize morbidity and mortality.

Standards for Safe Anesthesia

1. Pre-Anesthesia Evaluation:
• Thorough history (medical, surgical, allergy, drug use).
• Physical examination (airway assessment, cardiovascular, respiratory).
• ASA (American Society of Anesthesiologists) risk classification.
• Preoperative investigations (ECG, blood tests, chest X-ray if required).
2. Preparation and Monitoring:
• Functional anesthesia machine check before each case.
• Availability of emergency equipment (defibrillator, suction, oxygen supply, airway devices).
• Continuous monitoring: ECG, pulse oximetry, blood pressure, capnography, temperature.
• Intravenous access and readiness with resuscitation drugs.
3. During Anesthesia:
• Ensure correct drug, dose, route, and timing.
• Use of checklists before induction.
• Maintain normothermia and fluid balance.
• Communication between anesthetist and surgical team about intraoperative risks.
4. Post-Anesthesia Care:
• Transfer to recovery area with proper handover.
• Continuous monitoring until patient regains consciousness.
• Pain management protocols.
• Monitoring for complications (respiratory depression, hypotension, nausea/vomiting).

WHO and International Standards

• WHO–WFSA (World Federation of Societies of Anaesthesiologists) Guidelines: Every anesthetized patient should have continuous monitoring (oxygenation, ventilation, circulation, temperature).
• NABH Standards: Mandate pre-anesthesia check, safe drug labeling, and documentation of anesthesia events.
• JCI Standards: Require compliance with International Patient Safety Goals (IPSG), particularly correct patient, procedure, and site verification.
