Detailed Study Guide on Pre-operative and Intra-operative Nursing Processes
Pre-operative Checklist
Purpose of the Pre-op Checklist: Ensures all necessary preparations are completed before surgery.
Includes getting labs, inserting an ID, completing all necessary questions, and confirming patient consent.
Surgeon's Role: The surgeon will meet with the patient to discuss the procedure and obtain consent if it hasn't already been signed.
Anesthesia Consultation: Anesthesia staff will also meet with the patient, confirming details and asking several questions.
Sign the Site: Both the patient and surgeon, along with sometimes the anesthesia staff, will sign the operative site to confirm the correct location for surgery.
Pre-operative Medications
Common Pre-op Medications: Administered for specific reasons, including:
Antibiotics:
Purpose: Prophylactic use to prevent infections during surgery even in sterile Operating Rooms (OR).
Administration Timing: Ideally, should be given 30 minutes to an hour prior to surgery, before entering the OR.
Anticholinergics:
Purpose: To dry secretions and prevent issues during general anesthesia, especially when a breathing tube is involved.
Examples: Atropine and scopolamine are commonly used.
Antiemetics:
Purpose: To control nausea and vomiting, reducing aspiration risk.
Example: Ondansetron, given prior to waking the patient from anesthesia.
Sedatives and Analgesics:
Benzodiazepines: Used for sedation and anxiety relief.
Examples include midazolam and lorazepam.
Midazolam: More sedating and has an amnesic effect.
Lorazepam: Focus on reducing anxiety.
Reversal Agent: Flumazenil is used to reverse the effects of benzodiazepines in case of over sedation.
Opioids: Used for pain management.
Example: Fentanyl.
Reversal Agent: Meperidine or Naloxone can be used to reverse opioid effects.
Monitoring Patient Safety
Important Monitoring Concerns: Benzodiazepines and opioids can cause respiratory depression.
Signs include shallow respiratory rate and low oxygen saturation (O2 sat).
Continuous monitoring of the patient’s airway and breathing is crucial during sedation and anesthesia.
Safety and Positioning in the OR
Preparing for Surgery: Before surgery begins, it's essential to position the patient correctly:
Ensure Comfort: Use padding for bony prominences to prevent pressure sores, and maintain proper alignment for the surgical approach.
Prevent DVTs: Apply Sequential Compression Devices (SCDs).
Grounding Measures: Use grounding pads to prevent fires caused by surgical tools such as cautery devices.
Surgical Site Preparation
Chlorhexidine Scrubs:
Used for cleaning the surgical site effectively prior to surgery.
Patients may be instructed to use chlorhexidine soap at home or pre-operatively in the hospital.
Draping: After cleaning, sterilize the area with chlorhexidine iodine scrub, ensuring a sterile field and draping appropriately for the surgical procedure.
Latex Allergies: Check for potential latex allergies. Food allergies such as to bananas and kiwis could signify a latex allergy.
Anaphylaxis Signs and Screening
Signs of Anaphylaxis include:
Swelling of neck and tongue, hypotension, tachycardia, and bronchospasms.
Ensure to monitor ventilation changes in intubated patients since signs like stridor may not be audible.
If only one vital sign change is observed, other causes must be explored before concluding an allergic reaction.
Malignant Hyperthermia
Definition: A rapid rise in temperature due to an adverse reaction to anesthesia.
At-Risk Populations: Higher incidence in individuals with red hair and certain genetic predispositions.
Management: Immediate administration of dantrolene can reverse symptoms.
Timing: Can occur any time from initiation of anesthesia to several hours post-op.
Hypothermia in the OR
Environmental Factors: The OR is cold to reduce infection risk, leading to potential hypothermia in sedated patients.
Risk of temperatures falling to around 34°C, which could lead to complications such as cardiac arrest or blood flow issues.
Preventive Measures: Use warm blankets, hot packs, and devices like Bear Huggers to maintain body warmth post-surgery.
Time-Out Procedure
Importance of Time-Out: Conducting a time-out is vital before any invasive procedure, ensuring safety and accuracy.
Procedure for Time-Out:
Announce the patient's name, date of birth, known allergies, procedures to be performed, and the involved medical personnel.
Example: “I have patient Tori Merrick, DOB 07/03/1997, no known allergies, procedure: right sided chest tube insertion.”
Documentation: Ensure all time-out information is documented meticulously in the patient's records.
Roles of Operating Room Nurses
Roles in the OR:
Scrub Nurse: Maintains sterile field and assists directly during the surgery, handling instruments and aiding the surgeon.
Circulating Nurse: Monitors room conditions, patient status, and manages supplies.
Example: If a specific retractor is requested mid-surgery, the circulating nurse fetches it promptly.
Interoperative Care: The circulating nurse is responsible for tracking estimated blood loss and urine output, and communicating pre-and post-operative reports.
