Q

assent versus consent

A

assent is the minor agreeing with what the parents are consenting to. if the patient does not want the spine surgery and is in her teens, but the parents do- and she is old enough to understand the implications-cancel that case so they can talk more

how to perform caudal anesthesia
performed under GA. lateral decubitus with knees and hips flexed our cat position. place IV gatherer (22g <2 years, 20g >2 years, 18g if threading epidural catheter) at 45 degree angle. feel sudden give as needle advances through sacrococcygeal ligament. reduce angle of needle. still do test dose with .5mcg/kg epi.
88
caudal dosing for genital and anal surgery
.5-.75mL/kg (.5mL/kg sacral)
89
caudal dosing for lower abdomen and extremity surgery
1mL/kg (dosing for sacral up to low thorax)
90
caudal dosing for abdominal incision
1-1.25mL/kg (1.25mL/kg sacral to mid thorax dosing
91
caudal additives: epinephrine
test dose .5mcg/kg increase duration is theory theoretical neurological complications
92
caudal additives: clonidine
close 1-2mcg/kg increase in duration of epidural by 2-3 hours increased sedation scores, potential for hypotension and respiratory depression in some infants
93
maximum doses of lidocaine
5mg/kg, 7mg/kg with epinephrine
94
maximum doses of bupivicaine
2.5mg/kg, 3mg/kg
95

97
traveling post anesthesia: consider having these available
appropriately sized ambu bag oxygen source (blow by v face mask v nasal cannula) monitoring (pulse ox only v ecg and/or BP) emergency medications (atropine, succinylcholine, epinephrine) pain medications treatment for emergence delirium (dexmedetomidine, propofol, fentanyl) lateral position
