Study Notes

Surgical Techniques and Instrumentation

Reverse Cutting: Cutting edge positioned on the outer curvature, primarily used for retention sutures in skin closure, fibrous tissue, and ligaments.
Regular Cutting: General purpose cutting tool for various surgical applications.
Reverse Suctioning Cutting: Specialized tool, specifics not provided.

Skin Antiseptic Preparation

The purpose is to minimize microorganisms in the surgical field, preventing surgical site infections (SSIs).
Effective skin preparation removes debris, cleanses skin, reduces resident and transient microbes to a minimum, and inhibits microbial growth.
Skin serves as the body's first line of defense, but surgical incisions increase vulnerability to infections.
Surgical site infections are a common complication, often causing significant healthcare costs.
The first antiseptic skin agent in surgery was introduced by Joseph Lister, reducing postoperative mortality from sepsis during limb amputations.

Common Skin Preparation Agents

Iodophors and chlorhexidine gluconate (CHG) are the most frequently used antiseptic agents in modern surgical settings.

Grasping Instruments

Designed for manipulating and stabilizing tissues during surgery.
Tissue forceps, including non-ratcheted styles known as pickups or thumbs, come in various sizes and teeth configurations.
Bonney Forceps: Grasp fascia during abdominal surgeries and large orthopedic closures.
Babcock Forceps: Grasp delicate tissues such as the intestine or ovaries.
DeBakey Forceps: Primarily used in cardiovascular surgery for delicate tissue handling.
Single and multiple tooth thumb forceps: Used for tougher tissues with variations in teeth for better grip.

Needle Holders

Available in various sizes; Mayo-Hegar needle holders are commonly used for suturing.

Patient Positioning and Safety

Proper positioning maintains patient dignity, comfort, and optimal surgical access.
Common positions: Supine, Prone, Lateral, Lithotomy, Jackknife, Fowler's, Trendelenburg, and Reverse Trendelenburg.
Specific positions required for different procedures, such as side-lying for spinal anesthesia and dorsal recumbent for female catheterization.

Anesthesia

General Anesthesia: Induces reversible loss of consciousness and pain sensation by inhibiting neuronal impulses in the CNS.
Can lead to adverse effects, including malignant hyperthermia and postoperative nausea/vomiting.
Induction Agents: Propofol, Barbiturates, Etomidate, Ketamine, and Benzodiazepines are utilized for sedation and amnesia.

Risk Associated with Anesthesia

Muscle relaxants, including depolarizing (Succinylcholine) and nondepolarizing agents (Vecuronium, Atracurium), ensure muscle relaxation during major surgeries.
Stages of anesthesia progress from loss of consciousness to surgical anesthesia with necessary interventions from nursing staff during the process.

Opioids in Surgical Settings

Opioids such as Fentanyl, Sufentanil, and Morphine provide analgesia for preoperative and postoperative pain.
Risks include central nervous system depression, delayed recovery, and potential for postoperative constipation and urinary retention.

Surgical Incisions

Made through the skin to facilitate surgical procedures. The surgeon aims to select the most suitable incision type for the specific procedure involved.
Layers of the abdominal wall include skin as the outermost layer, vital for surgical considerations.
