Anesthesia, essays and researches

Although anesthesiology has grown tremendously and although anesthesiologists play a crucial role in the perioperative management of patients and also outside operating theater (OT) such as critical care, pain clinic, and labor analgesia, they do not get due recognition. We conducted a study to assess the awareness about the role of anesthesia and anesthesiologists among patients scheduled to undergo surgery in a Government Tertiary Care Teaching Women and Children Hospital. ⋯ Most of the participants were not aware of the role of anesthesia and anesthesiologists inside and outside OT. Although this could be attributed to their lower level of education, the fraternity of anesthesiologists has to educate patients and surgeons about the role of anesthesia.

The quest for an ideal sedative during regional anesthesia is on. Although propofol has been accepted as a sedative intraoperatively, it can be associated with troublesome hemodynamic changes. Dexmedetomidine is a new alpha 2 agonist used widely for sedation. ⋯ Dexmedetomidine at equivalent doses of propofol has a similar hemodynamic and respiratory effect, similar surgeon's satisfaction score, higher patient's satisfaction score, and no significant side effects in ASA I/II patients. Thus, dexmedetomidine may prove to be a valuable alternative to propofol for sedation in patients undergoing upper limb surgeries in brachial plexus block.

Various adjuvants have been introduced to decrease the dose of volatile agents and their side effects. Dexmedetomidine a potent alpha-2 adrenoreceptor agonist is one such agent. Our objective is to assess the effect of preanesthetic dexmedetomidine on isoflurane consumption and its effect on intraoperative hemodynamic stability and recovery profile. ⋯ Preanesthetic bolus dose of dexmedetomidine is a useful adjuvant to reduce isoflurane consumption.

Transversus abdominis plane (TAP) block has been used to provide intra- and post-operative analgesia with single incision laparoscopic (SIL) bariatric and gynecological surgery with mixed results. Its efficacy in providing analgesia for SIL cholecystectomy (SILC) via the same approach remains unexplored. ⋯ USG bilateral TAP blocks were not effective in decreasing 24 h morphine requirement as compared to local anesthetic infiltration in patients undergoing SILC although it provided some analgesic benefit intraoperatively and in the initial 4 h postoperatively. Hence, the benefits of TAP blocks are not worth the effort and time spent for administering them for this surgery.

Catheter-related bladder discomfort (CRBD) is the most distressing symptom in patients due to intraoperative urinary catheterization. Amikacin significantly inhibits detrusor contraction evoked by prejunctional stimulation. ⋯ Amikacin can significantly reduce the incidence and severity of CRBD in the first few hours after surgery.
