Anesthesia safety is an area of debate amongst surgeons, and there is no right answer. We are creatures of habit often without the hard data to back up our habits. Yes, a TT can be done under local or tumescent anesthesia (minus muscle repair although some practitioners are now numbing the fascia with local too). It can be done under MAC anesthesia (monitored IV sedation + local anesthesia). It can be done under general anesthesia with paralysis and gas. I have done all three. The nexus of the debate over TTs and anesthesia involves thromboembolic events (DVT>>PE). GA relaxes and dilates the venous system, and in conjunction increased intra-abdominal pressure, can, in certain patients, lend itself to clot formation (so the theory goes). Some surgeons argue that MAC anesthesia is "safer" due to the absence of venous dilation, paralysis, etc. I am uncertain of the veracity of this. Propofol (a primary drug used in MAC) also causes venodilation. If muscle repair is in order, then either MAC or GA is required. Most post-pregnancy TT patients require muscle repair and to not do so is a disservice to your body IMO. The question is why are you afraid of GA? I tell patients driving your car around is more dangerous from a statistical standpoint. When executed by a competent practitioner, its uber safe. Good luck.
