Study Notes

Preoperative Assessment, Premedication, & Perioperative Documentation

Cornerstones of effective preoperative evaluation: History and physical examination, complete medication list, allergies, and past anesthetic responses.
Risk-benefit discussion: Surgeon's responsibility, not the anesthesiologist's.
ASA classification: Used to determine relative risk in many countries.
Cardiovascular investigations: Same indications in surgical patients as in general patients with similar medical conditions.
Blood glucose control: Hemoglobin A1c assessment for long-term glucose control.
High-risk thrombosis patients: Chronic anticoagulants replaced by intramuscular low-molecular-weight heparins or intravenous unfractionated heparin.
Postponing elective surgery: Postpone all but mandatory emergency surgery for at least 1 month after coronary intervention.
Fluid restriction pre-anesthesia: No data to support fluid restriction beyond 2 hours before general anesthesia for healthy patients.
Preoperative testing utility: Discriminates between avoidable perioperative risk and risks detected by the test, or correction of the abnormality.
Test sensitivity and specificity: High sensitivity means low false negatives, and high specificity means low false positives.
Premedication purpose: To be given purposefully, not routinely.
Preoperative evaluation purpose: Identify patients with treatable conditions, evaluate those whose condition is too poor for surgery, identify patients likely improve through medical therapy before elective surgery.
Preoperative evaluation contents: Medical history, physical exam, diagnostic tests, imaging procedures, consultations, and discussion with patient and family members.
Anesthetic plan adaptation: Preoperative evaluation may require adjusting the anesthetic plan.
Cardiovascular issues: Guidelines for preoperative cardiac assessment are regularly updated and available from the American College of Cardiology/American Heart Association and from the European Society of Cardiology, additional specifics are in Chapter 21.
Pulmonary issues: Postoperative respiratory depression and failure are issues with obesity, obstructive sleep apnea, and patients 60 years old or older with chronic obstructive lung disease.
Endocrine and metabolic issues: Target blood glucose concentration for better outcomes, but tighter control is not always necessary.
Diabetes mellitus evaluation: Obtain pre-operative blood glucose measurements for diabetic patients.
Coagulation issues: Important to manage patients taking warfarin and other anticoagulants, patients with coronary disease on clopidogrel or related agents, those receiving anticoagulant medication in the perioperative period may need bridging therapy.
Gastrointestinal issues: Aspiration, avoid gastric emptying for surgical patients , especially those who have recently eaten a meal.
Preoperative physical examination: Important to check vital signs, airway, heart, and lungs, and any neurological deficits that could inhibit procedures.
Preoperative testing: Avoid routine testing, only if necessary based on a patient's individual history and risk profile; important tests include blood tests, electrocardiograms, and chest X-rays.
Premedication importance: A study showed that pre-operative visits from anesthesiologists were more effective in reducing anxiety than pre-operative medication.
Documentation importance: Provide quality, safe, and cost-efficient care by carefully documenting all aspects of patient's care.
Intraoperative anesthesia record: Terse, pertinent, and accurate record of intraoperative monitoring and procedures.
Postoperative notes: Include patient's recovery, anesthesia-related complications, and physician's disposition, important for follow-ups and risk assessment.
