    For elective surgery in Patients with hypopituitarism, like you, it’s necessary to correct the electrolyte balance in the blood.

    You should be instructed on your prepped visit by a surgical service. But in general, the preparation is the same regardless of the kind of anesthesia, local or general.

    You most definitely should stop taking the blood thinners before your surgery, otherwise, the surgery will be rescheduled. There are several classes of blood thinners, antiplatelet drugs such as Plavix and Aspirin, usually stopped 5 to 7 days preop. For some Surgeries, Aspirin could be continued. Also, there are medications that block the clotting factors such as Coumadin aka Warfarin, and the newest, like Eliquis. Those should be stopped at least 1 week and 48 to 72 hours before the surgery at the latest.

  • Can general anesthesia cause lung problems?

    General anesthesia per se could not affect healthy lungs. However inhalational anesthetic is usually avoided in Patients with pneumonia or severe COPD because it potentially can exasperate hypoxia, which is a low oxygen concentration in blood. In that case, it’s preferably to use total intravenous general anesthesia instead of inhalational. Also in emergent surgeries, there’s a risk of pulmonary aspiration in Patients with full stomachs during induction of anesthesia. That could cause chemical pneumonitis and subsequent pneumonia and ARDS aspiration respiratory distress syndrome. It’s avoidable with rapid sequence induction and patient positioning. In general, it’s very uncommon to have lung problems from anesthesia. READ MORE

  • local anesthesia

    You are totally right. It’s extremely rare to get urinary retention from infiltration with a local anesthetic. It’s more common with Epidural or Spinal Anesthesia when local anesthetic blocks the nerves which send signals to the bladder. In my opinion, you experienced the reaction to methylparaben. It’s a preservative in dental Xylocaine. That means that you can safely receive this local anesthetic without that preservative if you will have another surgical procedure. Just mention to the Surgeon that you had the complication from methylparaben in the Xylocaine vial. READ MORE

  • Are you sedated for a bone marrow biopsy?

  • Can anesthesia cause liver damage?

    The short answer is no. Hepatitis could be caused by viruses or toxins. Balanced general anesthesia is not toxic to the liver. On the contrary, by supporting optimal blood supply to the liver and other vital organs it protects them. Historically there were inhalational anesthetics that were hepatotoxic after prolonged exposures during long surgical procedures, such as Halothane, but it’s off the market. Theoretically, another inhalational anesthetic Sevoflurane, which is currently used, has a metabolite called compound A, which could be hepatotoxic, but its metabolism is insignificant even after prolonged exposure and no cases of liver damage have been reported.
