Chapter 17 Care of Intraoperative Patients
Members of the Surgical Team • Surgeon and surgical assistant • Anesthesia providers: • Anesthesiologist and CRNA • Holding area nurse • Circulating nurse • Scrub nurse • Surgical technologist • Specialty nurses
Environment of the Operating Room • Preparation of the surgical suite and team safety • Layout • Health and hygiene of the surgical team • Surgical attire • Surgical scrub
Anesthesia • Induced state of partial or total loss of sensation, occurring with or without loss of consciousness • Used to block nerve impulse transmission, suppress reflexes, promote muscle relaxation, and, in some cases, achieve a controlled level of unconsciousness
General Anesthesia • Reversible loss of consciousness induced by inhibiting neuronal impulses in several areas of the central nervous system • Involves a single agent or a combination of agents
Four Stages of General Anesthesia • Stage 1—analgesia and sedation, relaxation • Stage 2—excitement, delirium • Stage 3—operative anesthesia, surgical anesthesia • Stage 4—danger • Emergence—recovery from anesthesia
Administration of General Anesthesia • Inhalation • IV injection • Balanced anesthesia • Adjuncts to general anesthetic agents: hypnotics, opioid analgesics, neuromuscular blocking agents
Balanced Anesthesia • Combination of IV drugs and inhalation agents used to obtain specific effects • Example: thiopental for induction, nitrous oxide for amnesia, morphine for analgesia, and pancuronium for muscle relaxation
Complications from General Anesthesia • Malignant hyperthermia; possible treatment with dantrolene • Overdose • Unrecognized hypoventilation • Complications of specific anesthetic agents • Complications of intubation
Local Anesthesia • Briefly disrupts sensory nerve impulse transmission from a specific body area or region • Delivered topically and by local infiltration • Patient remainsconscious and able to follow instructions
Regional Anesthesia • Type of local anesthesia that blocks multiple peripheral nerves in a specific body region • Field block • Nerve block • Spinal block • Epidural block
Complications of Local or Regional Anesthesia • Anaphylaxis • Incorrect delivery technique • Systemic absorption • Overdose • Local complications
Treatment of Complications • Establish open airway. • Give oxygen. • Notify the surgeon. • Fast-acting barbiturate is usual treatment. • Epinephrine for unexplained bradycardia.
Conscious Sedation • IV delivery of sedative, hypnotic, and opioid drugs to reduce the level of consciousness. • Patient maintains a patent airway and can respond to verbal commands. • Amnesia action is short with rapid return to ADLs. • Etomidate, diazepam, midazolam, meperidine, fentanyl, alfentanil, and morphine sulfate are the most commonly used drugs.
Collaborative Management • Assessment • Medical record review • Allergies and previous reactions to anesthesia or transfusions • Autologous blood transfusion • Laboratory and diagnostic test results • Medical history and physical examination findings
Risk for Perioperative Positioning Injury Interventions include: • Proper body position • Risk for pressure ulcer formation • Prevention of obstruction of circulation, respiration, and nerve conduction
Impaired Skin Integrity and Impaired Tissue Integrity Interventions include: • Plastic adhesive drape • Skin closures, sutures and staples, nonabsorbable sutures • Insertion of drains • Application of dressing • Transfer of patient from the operating room table to a stretcher
Potential for Hypoventilation • Continuous monitoring of: • Breathing • Circulation • Cardiac rhythms • Blood pressure and heart rate • Continuous presence of an anesthesia provider
