Study Notes
Classifications of Surgery
- Surgery is classified based on seriousness, urgency, and purpose; some procedures may fit multiple classifications.
- Classification influences the level of care required for the patient.
Classification: Seriousness
- Major surgeries involve extensive reconstruction, posing higher risks; examples include coronary artery bypass and lung lobe resection.
- Minor surgeries entail minimal alterations with lower risks, often correcting deformities; examples include cataract extraction and tooth extraction.
Classification: Urgency
- Elective surgeries are based on patient choice, not immediately necessary; examples include hernia repairs and facial plastic surgery.
- Urgent surgeries are necessary for health but not immediate emergencies; examples include cancerous tumor excision and gallbladder removal.
- Emergency surgeries must be performed immediately to save life or body function; examples include appendectomy and traumatic amputation.
Classification: Purpose
- Diagnostic surgeries confirm diagnoses through exploration and tissue removal; an example is a breast mass biopsy.
- Ablative surgeries involve excising or removing diseased body parts.
- Palliative surgeries alleviate symptoms without curing conditions.
- Reconstructive/restorative surgeries aim to restore function and appearance to damaged tissues; examples include scar revision.
- Procurement for transplant is necessary for transplanting organs.
- Constructive surgeries involve the rebuilding of structures, such as the jaw.
- Cosmetic surgeries enhance appearance and may also involve restorative care following trauma.
Types of Surgery Techniques
- Laparoscopic surgery is minimally invasive, utilizing CO2 to create space; movement post-surgery is crucial for recovery, particularly for patients with respiratory issues.
- Robotic surgery allows surgeons to operate from a console, maintaining sterility.
Types of Anesthesia
- General anesthesia results in complete loss of sensation and consciousness, involving three phases: induction, maintenance, and emergence.
- Induction involves administration of anesthetics and intubation.
- Maintenance includes patient positioning and surgical preparation, ensuring appropriate anesthesia levels.
- Emergence is when anesthetics decrease, and the patient begins to awake.
Regional Anesthesia
- Administered via spinal, epidural, or peripheral nerve blocks; consciousness remains but the patient is sedated, with risks such as upward spread causing respiratory issues.
Local Anesthesia
- Blocks nerve conduction at specific sites, either injected or applied topically; results in loss of sensation localized to the area.
Conscious/Moderate Sedation
- Provides sedation for procedures not requiring full anesthesia, allowing patients to remain responsive yet comfortable.
