Q

At hysteroscopy, the nurse tells you you have reached a 3L +ve balance of glycine. How should you manage this?

A
  • drain uterine glycine
  • FBC, U&E, creatinine, glucose, ammonia, plasma osmolality
  • treat with hypertonic saline if Na less than 120
  • aim for slow correction of hyponatremia
  • frusemide if pulmonary oedema
  • open disclosure
  • documentation

Q

what does direct coupling refer to with regards electrosurgical injury

A
  • current finds path of least resistance e.g. between retractor and electrode or clips and staples, leading to burns

Q

What can increase the risk of electrosurgical injury?

A
  • incorrect placement of electrode onto skin leading to burn injury
  • ## metalware - e.g. burns at site of pacemaker

Q

list 3 types of electrosurgery injury that can occur at endoscopic surgery?

A

capacitive coupling - capacitance occurs when 2 conductors are separated by an insulator however this fails, and the current flows between the two conductors - causing unseen or unidentified injury

Q

list 3 types of electrosurgery injury that can occur at endoscopic surgery?

A
  • capacitive coupling - capacitance occurs when 2 conductors are separated by an insulator however this fails, and the current flows between the two conductors - causing unseen or unidentified injury
  • smoke injury
  • effect of laparoscopic field of view - injury outside of field of view
18
Q

Define electosurgery

A
  • use of an alternating current that travels as a circuit through the patient to achieve the desired effect
19
Q

what is the difference between household and elect

A
20
Q

what tests are available to assess for correct placement of the veress needle?

A
  • double pop on entry
  • saline withdrawal
  • opening pressures <8mmHg associated with success
21
Q

Describe the anatomy of the inferior epigastric artery

A
  • extension of the external iliac artery at point of crossing the inguinal ligament
  • curves forward in sub peritoneal tissue
  • ascends medially and superiorly
  • pierces the transversalis fascia
  • courses between rectus abdominus and rectus sheath
  • anastomoses above the umbilicus with superior epigastric branch of internal thoracic artery
  • located within 8cm from midline
  • located within 1/3 line from midline to ASIS
22
Q

Describe measures that you can take to avoid damage to the inferior epigastric artery

A
  • 2cm medial and superior to ASIS is safe
  • may be visible endoscopically but not by transillumination
  • port entry perpendicular to skin
  • port entry under direct vision
  • check for bleeding on removal of port
