Q/A

Introduction: Peri-operative nursing care refers to the holistic, patient-centered nursing management provided before, during, and after a surgical procedure to ensure optimum patient safety and recovery. It consists of three distinct phases:

1. Pre-operative Phase (অপারেশন-পূর্ব ধাপ)
2. Intra-operative Phase (অপারেশনকালীন ধাপ)
3. Post-operative Phase (অপারেশন-পরবর্তী ধাপ)

Onset (Beginning) and Termination (Ending) of Each Phase:

Four Essential Roles of a Nurse in Pre-operative Care:

1. Comprehensive Pre-operative Assessment & Baseline Data Collection: The nurse performs a complete head-to-toe physical assessment, records baseline vital signs, checks for drug/latex allergies, evaluates nutritional and fluid status, and verifies that necessary diagnostic reports (CBC, Coagulation profile, ECG, Chest X-ray, Blood grouping & cross-matching) are attached to the patient's chart.
2. Verification of Informed Consent: While the surgeon explains the procedure, the nurse acts as a patient advocate by verifying that the patient (or legal guardian) fully understands the surgery and has voluntarily signed the Informed Consent form prior to receiving any sedative pre-medication.
3. Pre-operative Patient Education & Psychological Support: The nurse alleviates surgical anxiety and teaches postoperative exercises, including deep breathing, effective coughing (splinting the incision), use of an incentive spirometer, leg exercises to prevent DVT, and early ambulation techniques.
4. Physical & Safety Preparation: The nurse ensures strict adherence to NPO (Nil Per Os) guidelines, performs surgical skin preparation and bowel/bladder emptying (catheterization if ordered), removes dentures, jewelry, nail polish, and prostheses, applies the patient identification wristband, and completes the Pre-operative Checklist.

Part 2: Who Gives Consent for a Minor Patient? (নাবালক রোগীর ক্ষেত্রে সম্মতি প্রদানকারী)

• Biological or Adoptive Parents (পিতা-মাতা): For a minor patient (typically under 18 years of age), a biological or legally adoptive parent (father or mother) has the primary legal authority to sign the informed consent.
• Court-Appointed Legal Guardian (আইনগত অভিভাবক): If parents are deceased, unavailable, or lack custody, a court-appointed legal guardian or custodian provides the consent.
• Emergency Exception (জরুরি জীবনরক্ষাকারী অবস্থা): In a life-threatening medical emergency where parents or legal guardians cannot be reached despite documented efforts, implied consent applies, and the surgeon/hospital authority may legally proceed to save the child's life.

Part 1: Why NPO (Nil Per Os / Nothing by Mouth) is Necessary Before Surgery

Maintaining NPO status prior to surgery is critically necessary for the following physiological reasons:

• Prevention of Pulmonary Aspiration: General anesthesia, regional anesthesia, and deep sedation relax the lower esophageal sphincter (LES) and abolish protective airway reflexes (such as the gag, cough, and swallowing reflexes).
• Avoidance of Mendelson's Syndrome (Aspiration Pneumonitis): If the stomach contains food or acidic fluid during anesthesia induction or intubation, passive regurgitation can occur. Inhaling acidic gastric contents into the lungs causes severe chemical pneumonitis (Mendelson's syndrome), airway obstruction, acute respiratory distress syndrome (ARDS), and potentially fatal asphyxiation.
• Reduction of Post-operative Nausea and Vomiting (PONV): An empty stomach significantly minimizes intraoperative and postoperative emesis.

Part 2: Pre-operative Fasting Duration (ASA Guidelines)

Introduction: The World Health Organization (WHO) Surgical Safety Checklist is a globally standardized patient safety tool designed under the "Safe Surgery Saves Lives" initiative to prevent wrong-site surgery, anesthesia errors, surgical infections, and retained instruments. It is divided into three critical phases corresponding to the workflow of a surgical procedure:

1. Phase 1: Sign In (সাইন ইন)
2. Phase 2: Time Out (টাইম আউট)
3. Phase 3: Sign Out (সাইন আউট)

Detailed Timing and Clinical Verification of Each Phase:

Surgical Count Protocol: To prevent Retained Surgical Items (RSI) inside a patient's body cavity, the Scrub Nurse and Circulating Nurse jointly perform audible and visual counts of all swabs/sponges, sharps (needles/blades), and instruments at five standardized intervals during surgery:

If a mismatch or discrepancy occurs during any surgical count of swabs, instruments, or needles, the operating room nurses must immediately follow a strict step-by-step emergency protocol:

1. Immediate Notification to the Surgeon & Suspension of Closure: The Circulating Nurse must immediately and clearly inform the lead surgeon and the surgical team of the missing item (type and quantity) so that further wound closure is paused (if patient stability permits).
2. Complete Recount of All Items: The Scrub Nurse and Circulating Nurse immediately perform a systematic recount of all items in both the sterile and unsterile fields to rule out arithmetic error.
3. Thorough Search of the Sterile & Unsterile Environment:
   • Surgeon: Re-examines and palpates the surgical cavity/wound thoroughly.
   • Scrub Nurse: Searches the Mayo stand, back instrument table, surgical drapes, and folds of sterile towels.
   • Circulating Nurse: Searches kick buckets, floor, trash bins, linen hampers, under the OR table, and around the footstools. (No trash or linen is allowed to leave the OR until all counts are reconciled).
4. Intra-operative Radiographic Imaging (X-ray / Fluoroscopy): If the missing item is still not located, the nurse arranges an intra-operative X-ray (since surgical swabs and instruments are radiopaque) to scan the entire surgical field before the patient leaves the Operating Room, and ensures a radiologist/surgeon reviews the film immediately.
5. Accurate Documentation & Incident Reporting: Document the discrepancy, all corrective steps taken, the intraoperative X-ray result, and the final outcome in the perioperative nursing record, and complete an institutional Incident Report for quality assurance.

Below are the detailed clinical manifestations (signs & symptoms) and evidence-based nursing management for two major post-operative complications: (1) Post-operative Hemorrhage and (2) Deep Vein Thrombosis (DVT) (along with a bonus clinical table for Surgical Wound Infection & Wound Dehiscence):

1. Post-operative Hemorrhage (অপারেশন-পরবর্তী রক্তক্ষরণ)

Post-operative hemorrhage is excessive blood loss occurring internally or externally from the surgical site due to slipped ligatures (sutures), clot dislodgement, or coagulopathy.

2. Deep Vein Thrombosis - DVT (গভীর শিরায় রক্ত জমাট বাঁধা)

Deep Vein Thrombosis (DVT) is the formation of a blood clot (thrombus) inside a deep vein—most commonly in the calf or thigh muscles—due to Virchow's Triad (venous stasis from immobility, hypercoagulability after surgery, and endothelial injury).
