Study Notes

Anatomy and Surgical Procedures

Ligament of Treitz connects the duodenum and jejunum, plays a role in gastrointestinal anatomy.
Blood supply to the gastrointestinal tract originates from the celiac trunk and includes branches: splenic, common hepatic, and left gastric arteries.
The Superior Mesenteric Artery supplies the small intestine and parts of the colon; the Inferior Mesenteric Artery supplies the rectum and lower colon.

Bowel Isolation Techniques

Immediate implementation upon clamping and opening the GI tract to prevent contamination and mechanical metastasis of malignant cells.
Bowel instruments must be separated from clean instruments; placed in a K-basin.
Extra draping around the incisional area aids in maintaining a clean environment during closure.
Surgical team changes gloves and gowns post-anastomosis before closure.

Surgical Staplers

GIA (Gastrointestinal Anastomosis) stapler performs cutting and stapling simultaneously; ideal for side-to-side anastomosis.
TA (Thoracoabdominal Stapler) staples tissues requiring manual cutting.
EEA (End to End Anastomosis) or ILS (Intraluminal Stapler) used primarily in lower bowel procedures.

Mesenteric Repair

Requires repair of mesenteric defects following bowel removal to prevent post-operative bowel entrapment and obstruction.

Bariatric Surgery

Roux-En-Y Gastric Bypass reduces stomach size and bypasses the duodenum, promoting fullness with fewer calories absorbed.
Gastric Lap Band involves an adjustable band that restricts the amount of food intake.
Sleeve Gastrectomy removes 85% or more of the stomach, significantly reducing food capacity.

Colostomy and Ileostomy

Temporary colostomy allows bowel rest or healing from anastomosis and is often related to imminent perforation risks.
Hartmann's Procedure is performed in urgent situations, leading to a proximal colostomy and closed distal stump.
Permanent colostomy may be indicated post-cancer resections.

Uterine Procedures

Uterine ligaments include cardinal, uterosacral, round, and broad ligaments (CURB).
D&C (Dilation and Curettage) is conducted for heavy bleeding, miscarriage recovery, or abortion follow-up.
Vault Count pertains to the observation of cervix-related surgical procedures.

Pneumoperitoneum

Achieved using a Veress needle; volume typically ranges from 2.5 to 4 liters, with a pressure of 14-16 mmHg to avoid complications.

Hysterectomy Types

Total Abdominal Hysterectomy: removal of both uterus and cervix.
Partial/Subtotal Hysterectomy: uterus alone is removed; radical forms include removal of surrounding reproductive structures.
Bilateral Salpingo-Oophorectomy (BSO) entails removing fallopian tubes and ovaries.

Ovarian Cancer and Pelvic Exenteration

Ovarian cancer is often asymptomatic and diagnosed late, commonly affecting women 50-60 years old.
Pelvic Exenteration involves extensive removal of pelvic organs, indicated for persistent cervical carcinoma after radiation.

Counts in Surgery

Count protocols differ for laparoscopic and open procedures, focusing on initial, closing, and final count stages.

Cystoscopy Procedures

Used for diagnostic assessments, flexible for men and rigid for women.
TURP involves removing enlarged prostate tissue and operates under specific irrigation fluid considerations to prevent electrolyte imbalances.

Kidney Transplantation

Primarily laparoscopic; left kidney is preferred donor due to longer vein.
Transplant considerations include donor health, brain death, and recipient readiness including nutritional support and dialysis.

Prostate Surgical Procedures

Prostatectomy removes prostate tissue; various approaches include suprapubic and retropubic methods.
Nerve-sparing techniques aim to preserve erectile function while addressing cancer.

Urinary and Rectal Reconstruction

Ileal conduit and Kock pouch are surgical options for urinary diversion post-radical cystectomy.
Basic terminology in urology includes ureteroscopy, pyelolithotomy, and orchidopexy for undescended testicle correction.

Cardiovascular Anatomy and Interventions

Heart anatomy includes four chambers and valves ensuring proper blood flow.
Nursing interventions focus on monitoring during cardiac catheterization and anesthesia induction.
CPBM allows temporary heart and lung function during surgeries. Medications such as heparinized solutions and vasodilators support surgical procedures.

CABG and Pacemaker Use

CABG is indicated for severe coronary artery disease, utilizing vessels like the left internal mammary artery for grafting.
Pacemakers are implemented for bradycardia or tachycardia, normalizing heart rhythms.

Respiratory System Anatomy and Procedures

Mediastinal lymph nodes are significant for lung cancer diagnoses; VATS is a minimally invasive technique for lung surgeries.
Double lumen ETT allows single-lung ventilation during procedures like lobectomy or pneumonectomy, ensuring controlled oxygenation.

Gastrointestinal Surgery

Ligament of Treitz: Connects duodenum to jejunum.
Blood Supply:
- Celiac trunk provides splenic, common hepatic, and left gastric arteries.
- Superior mesenteric artery feeds small intestine and two-thirds of the transverse colon.
- Inferior mesenteric artery supplies transverse colon to rectum.
Abdomen Sequence for Surgery: clamp - clamp - cut - tie.
Bowel Isolation Techniques: Started upon GI tract clamping to prevent contamination; includes irrigation and wound closure preparation.
Bowel Instruments: Separated from clean instruments; placed in a K-basin for hygiene.
Extra Draping: May be added around the incision area for enhanced closure protection.
Glove Change Protocol: Surgical team changes gloves and gowns after anastomosis before closure.
Staplers:
- GIA: Cuts, staples, and divides simultaneously; suitable for side-to-side anastomosis.
- TA: Manual cutting needed while stapling tissues.
- EEA: Cuts in circular fashion for end-to-end or end-to-side anastomosis.
Mesenteric Repair: Necessary after bowel removal to prevent post-operative complications.
Nissen Fundoplication:
- Plication shortens stomach tissue around the esophagus.
- Crurrorhaphy provides permanent suture repair.
- Critical to maintain appropriate suturing tension to avoid GERD or food obstruction.
Bariatric Surgery Types:
- Roux-En-Y Gastric Bypass: Reduces stomach size, connects directly to jejunum, enhancing fullness sensation.
- Gastric Lap Band: Adjustable band inserted around the stomach to limit food intake.
- Sleeve Gastrectomy: 85% or more of the stomach is removed.
Colostomy/Ileostomy:
- Temporary for bowel rest; performed when bowel is at risk of perforation.
- Hartmann's Procedure creates a temporary colostomy in emergencies, with a subsequent bowel reconnection.
- Permanent colostomy (rosebud) done after bowel resection in cancer cases.
Abdominoperineal Resection: Involves removal of rectal tumors close to the anus; requires dual surgical teams for efficiency.

Gynaecology

Uterine Ligaments: Include cardinal, uterosacral, round, and broad ligaments.
D&C (Dilation and Curettage): Procedure to scrape uterine lining; indicated for heavy bleeding or post-miscarriage cleanup.
Vault Count: Conducted during cervix manipulation to track tissue during surgery.
Pneumoperitoneum:
- Created with a Veress needle, using 2.5-4 L volume and maintaining pressure between 14-16 mmHg.
Hysterectomy Types:
- Total: removes uterus and cervix.
- Partial/Subtotal: removes only the uterus.
- Radical: extensive removal including uterus, cervix, fallopian tubes, ovaries, and pelvic lymph nodes.
Endometrial Ablation: Utilizes non-electrolytic ionic medium for treating menorrhagia; involves monitoring for hyponatremia.

Cardiovascular Surgery

Heart Anatomy: Comprised of four chambers: right atrium, right ventricle, left atrium, left ventricle; four valves regulate blood flow.

Nursing Interventions: Essential to monitor cardiac catheterization results for surgical preparation and suture needs.
General Anesthesia: Critical for cardiac operations with close monitoring of vital cardiac functions.
Cardiopulmonary Bypass Machine (CPBM): Temporarily substitutes heart and lung function, allowing for surgery without disrupting circulation.
