SOON after Jane Z. had her B-cup breasts augmented for the first time,  she realized she hadn’t gone big enough. So the second time, Jane Z.,  who preferred to not have her last name mentioned, was thrilled that she  could  choose her implant size during surgery.  
        
How? She was awake. Most women who get breast implants do so under  general anesthesia. But Jane. Z.’s doctor was Dr. Robert L. True of  Colleyville, Tex., one of more than 100 doctors nationwide who advocate  local anesthesia and sedation for aesthetic surgeries like breast  augmentations.  
 “They are talking to me the entire time,” Dr. True, an obstetrician and  gynecologist by training, said of the 75 patients whose breasts he has  enlarged in his accredited facility. Once the new implants are in, his  patients are propped up on the operating table, look in a mirror and  have their say. “They like that little bit of autonomy,” he said.  
 A lot of plastic surgeons consider it out of the question to do a breast  augmentation without an anesthesiologist or nurse anesthetist on hand,  partly because of the risk to the patient if something goes wrong. These  doctors say they cannot do their best work — dissecting a pocket for an  implant, then securing it  — without total control.  
 But lately, a set of doctors, most of whom have not come up through  plastic surgery, has been touting the awake option as a boon to patient  choice and as a safer option than general anesthesia. Breast  augmentation is often done in hospitals and accredited offices, but  awake breast surgery is usually done in an office that might not have  been vetted for safety by an accrediting organization.  
 “Problem is, doctors are doing large procedures on local with  quote-unquote sedation to circumvent the need for accreditation,” said  Dr. Lawrence S. Reed, the president of the American Association for the  Accreditation of Ambulatory Surgery Facilities.  
 For most of surgery, Jane Z., 48, who reviews medical charts for a  hospital, said she felt “pretty much out of it.” She added, “You’re  technically awake, but you remember nothing.” In a more coherent moment,  she did recall being asked, before Dr. True sewed her up, if her new  breasts were adequate. She asked to go slightly larger, and got her wish  for a DD cup.  
 “If you talk to 99 percent of women, they want input into what they are  going to look like,” said Dr. Jeffrey Caruth, an obstetrician and  gynecologist by training who now offers awake cosmetic surgery at his  office in Plano, Tex. “People are not coming to me because it’s cheaper.  They don’t want to be put to sleep.”  
 Doctors offering awake breast augmentation and awake abdominoplasty (a  tummy tuck) advertise on YouTube.com and  make the case for local anesthesia and sedation on their Web sites. In  the last few years, marketing for awake breast augmentation has ramped  up. No organization tracks how many doctors do the awake version of this  surgery (or of tummy tucks).  
 Dr. Anil K. Gandhi, who performs both awake procedures at his office in  Cerritos, Calif., said he had taught “more than  100 doctors” in two-day  $7,000 seminars for the National  Society of Cosmetic Physicians. His students are doctors who  typically did their residencies in ob/gyn or family medicine and who  take a weekend course (or two) to learn how to do aesthetic surgeries  with local anesthesia and sedation.  
 This shortcut  to practicing aesthetic surgery tends to outrage the  traditionalists. After all, board-certified plastic surgeons spend five  to eight years after medical school learning operations and  then have their surgical skills vetted in exams.  
 “Two-day courses, it’s just crazy,” said Dr. William P. Adams Jr., a  plastic surgeon in Dallas who teaches residents at the University of  Texas Southwestern Medical Center. “It took us six years to fully train  plastic surgeons to do breast augmentation.” He said it was  irresponsible  to let fuzzy-headed patients choose their implants. “They  don’t let people drive after a six-pack of beers,” said Dr. Adams, who  is an investigator for Mentor and Allergan, makers of breast implants  (and a consultant for Allergan). “How well will people choose an implant  size after narcotics?”  
 Dr. Adams and  other plastic surgeons say that mid-surgery consultations can be harmful  if the patient chooses implants too large for her chest.  Overaugmentation can produce unsightly rippling, said Dr. Mark L.  Jewell, a plastic surgeon who does breast augmentations with local  anesthesia and intravenous sedation in an accredited facility in Eugene,  Ore. “Decisions should be made ahead of time,” said Dr. Jewell, an  investigator for Mentor and Allergan as well as a consultant for  Allergan.
 Several doctors said that promoting local anesthesia and sedation for  aesthetic surgeries was just a gimmick that played down the  risks. “Promotion of these surgeries as so easy that only local  anesthesia is required, it’s intended to make someone think, ‘It’s not  serious,’ “ said Dr. Douglas R. Blake, an anesthesiologist in  Providence, R.I., who specializes in office-based procedures. “The  promise to get by with just local anesthesia may in fact be  shortchanging the patient.” Say a patient feels faint, or has a panic  attack mid-surgery, “who’s there to attend to the patient?” he asked.  
        
 Practitioners of awake breast augmentation offer patients sedation and  then pump in a numbing fluid. This liquid — which has been used for  years in a kind of liposuction called “tumescent” —  includes lidocaine,  an anesthetic, and epinephrine, which controls bleeding.  
 Cosmetic surgeons without residencies in plastic surgery  say that using  local anesthesia for breast augmentation promotes a faster recovery,  but plastic surgeons tend to dispute that. “No surgeon who performs  awake augmentation has ever proven in an independently monitored study  that their patients can be out to dinner that night and return to full  normal activities in 24 hours,” said Dr. John B. Tebbetts, a plastic  surgeon in Dallas.  
 Jane Z., who had her first breast augmentation with Dr. Tebbetts,  said  her recovery after that 2004 operation and the recent one with Dr. True  took roughly the same time. After general anesthesia, she said, she felt  woozy but not nauseated.  
 Aspiration — when stomach contents return to the mouth and are inhaled  —  is one rare complication of going under. But under  sedation, Dr. Blake   said, the protective reflexes in the airway may be reduced, making  aspiration a possibility.  
 Dr. Keith J. Ruskin, an anesthesiology professor at Yale  University School of Medicine,  said doctors using tumescent  anesthesia must avoid an overdose, which can lead to seizures and  abnormal heartbeats. Dr. Caruth gives his breast augmentation patients 5  to 10 milligrams of Valium and some Ativan (anti-anxiety drugs) for  minimum sedation.  If a patient wants moderate sedation, she must pay  $600 for an anesthesiologist. But not every doctor sedating patients for  breast augmentations believes less is more. Dr. Caruth said, “I see  these guys that say they do ‘awake’ and they slam the heck out of these  people with drugs.”  
 Dr. Gandhi, who trained as a general surgeon but is not board certified,  said his patients get minimal sedation. He wants them alert. “It’s more  safe,” he said. “Patients can scream and you would know, I can’t be  doing that, I can’t be putting my needle there,“ said Dr. Gandhi, whose  office is not accredited. Later, he clarified by e-mail: “For breast  augmentation the technique that I have implemented and teach for  tumescent anesthesia infusion results in excellent numbness, that the  patients do not feel a thing while I am operating.”
