A 65 /M is scheduled for hip replacement, left. PPHx – HPN, Diabetes. PE – Ht 165 cms, Wt 68 kg, BP 170/100, CR 92/min. Hgb 12.2gms. Best anesthetic technique of choice for this patient is:
TIVA
GETA
Epidural anesthesia w/ sedation
GA-LMA
Central neuraxial anesthesia is the best technique of choice for Hip Replacement for the ff. reasons EXCEPT:
Blunts the stress response to surgery
Decrease intraoperative blood loss
Provide better intraoperative muscle relaxation
Lower the incidence of thromboembolic events
Midline insertion of epidural needle at L2-L3 interspace is least likely to result in unintended meningeal puncture because ligamentum flavum in the midline at this level is:
shallowest posteriorly
farthest from the spinal meninges
thinnest, measuring 2 – 3 mm.
toughest posteriorly
The characteristic “gritty “ feel much like inserting a needle into a bag of sand on epidural needle insertion means that the needle is traversing the :
Inferior spinous process
Supraspinous ligament
Ligamentum flavum
Interspinous ligament
TRUE of the CSF EXCEPT:
Volume is approximately 100 – 160 ml in neonates
Produced in the choroid plexus and cerebral capillaries
Produced at the rate of 20 – 25 ml/hr
Removed by arachnoid villi in the superior saggital sinus
In majority of adult patients placed in the lateral position with his back flexed the tip of the spinal cord would most likely end at this level:
L3
L1
T12
L4
Needle used for epidural anesthesia:
Tuohy
Whitacre
Quincke
Sprotte
18 yr old patient for appendectomy was placed in the right lateral position for spinal anesthesia. As needle Is inserted in the midline bone is encountered at a deeper depth. Which bone is most likely contacted by the needle is:
Inferior spinous process
Superior spinous process
Vertebral lamina
Posterior spinous process
An epidural catheter advanced 7 cm into the epidural space may increase the risk of developing either one of the ff EXCEPT :
Unilateral block
High epidural anesthetic block
Subarachnoid block
Local anesthetic toxicity
The sensitivity of the standard test dose for epidural anesthesia has been shown to be markedly diminished in patients who are :
Sedated
pregnant
elderly
beta blocked
