The Prolonged Effect of a Spinal Adjuvant Drug or an Iatrogenic Complication: An Unprecedented

 Bupivacaine is one of the most widely used local anesthetics in spinal anesthesia. Clonidine is a known adjuvant added to prolong the duration of anesthesia. Amongst the complications related to spinal block, neurological complications can be the most troublesome.

 We presented a case where the reversal of motor and sensory blockade after spinal anesthesia with bupivacaine and clonidine was extremely delayed in the absence of any neurological injury.

 Such cases remind the significance of timely and elaborate assessment in the detection of iatrogenic complications and the unpredictability of physiological and pharmacological interactions.
