The case report here is a case of cesarean operation under subarachnoid block, which resulted after a failed lumber puncture, known to be "dry tap." The result is that it was uneventful surgery without any additive anesthetics being required after injecting 2.2 ml Bupivacaine 0.5% (H). Although cases have been reported with mixed experiences of dry tap and different causes are also explained, but still there is a need to find few other reasons for "dry tap." Hence, thought to present the case for putting forward a question that if there is any more cause for dry tap.
