Intravenous trimethaphan during epidural plus general anesthesia decreases the direct radial artery pressure lower than the brachial artery pressure.

STUDY OBJECTIVE: To determine whether vasodilators such as sodium nitroprusside (SNP) and trimethaphan (TMP) produce a pressure difference between the radial artery and the brachial artery during epidural plus general anesthesia or simple general anesthesia. DESIGN: Randomized study and prospective study. SETTING: Operating rooms of two hospitals. PATIENTS: 36 and 6 adult patients in the first and second studies, respectively, who received spherical acetabular osteotomy with induced hypotensive anesthesia. INTERVENTIONS: In the first study, 18 patients received epidural plus general anesthesia (epidural group) and 18 patients received general anesthesia alone (general group). All patients received the hypotensive drugs for more than 50 minutes each. In the second study, 6 patients received TMP-induced hypotension for 20 minutes under epidural plus general anesthesia. MEASUREMENTS AND MAIN RESULTS: In the first study, radial intra-arterial blood pressure (RIBP) and tonometric blood pressure (TBP) calibrated with oscillometric blood pressure of the arm were compared. In the second study, RIBP and the brachial intra-arterial blood pressure (BIBP) were compared. In the first study, the bias between RIBP and TBP for systolic, mean and diastolic blood pressure were significantly less during TMP-induced hypotension in the epidural group (-11.5 +/- 2.5 (mean +/- SD), -6.0 +/- 3.1, and -2.8 +/- 3.7 mmHg, respectively] than during SNP-induced hypotension in the epidural group and SNP- and TMP-induced hypotension in the general group (p < 0.01). The precision of systolic and mean pressures were significantly greater during TMP-induced hypotension in the epidural group (11.8 +/- 2.3 and 7.1 +/- 1.9 mmHg, respectively) than the other three hypotension groups (p < 0.01). In the second study, the bias between RIBP and BIBP for systolic, mean, and diastolic pressures were significantly less (p < 0.01), and precision was significantly greater during hypotension than during normotension (p < 0.01). CONCLUSIONS: Our results demonstrate that TMP decreases the direct radial artery systolic and mean pressures to levels below the brachial artery systolic and mean pressures in patients who received epidural plus general anesthesia.

Local versus general anesthesia for laparoscopic sterilization: a randomized study.

Despite the contention by some that local anesthesia is a preferred alternative to general anesthesia for laparoscopic sterilization, there have been no randomized studies comparing these techniques. To better characterize the relative safety and acceptability of these techniques for laparoscopic sterilization, we randomly assigned 100 women undergoing bipolar electrocoagulation or spring clip application to either local or general anesthesia. Of the 53 women assigned local anesthesia, four had their procedures completed using another technique because of technical problems related to obesity. Thirteen other obese women, however, underwent successful surgery with local anesthesia. Women undergoing local anesthesia had a slightly shorter anesthesia time (30 versus 36 minutes) and recovery room stay (65 versus 78 minutes). Women having general anesthesia were 2.3 and 1.5 times more likely to have maximum systolic and diastolic blood pressures above 160 and 90 mmHg, respectively. They were also 5.7 times more likely to have a maximum heart rate 110 or higher. Patient movement was reported to be a concern in five women undergoing general anesthesia, but in none having local anesthesia. An equal percentage (80%) of women in each group expressed satisfaction with their anesthetic technique.

Regional versus general anesthesia.

The debate continues as to whether regional anesthesia is safer than general anesthesia. However, the choice of anesthetic technique is a complex decision. This review of the most recent publications compares the safety of regional anesthesia with that of general anesthesia.

Teflon injection of vocal cords under general anesthesia: a new method.

Use of general anesthesia permits the injection of Teflon paste into immobile vocal cords in an accurate and predictable manner, with the help of a special endotracheal tube and jetted O2 or O2/n2O mixture. The authors position a nonfunctioning vocal cord so that when the functioning cord is fully adducted , the two cords are in perfect approximation for phonation. This has allowed marked improvement in effective expulsive postoperative coughing and vocalization. Debris is blown away from the operating side and not into the patient's trachea. If excessive injection of Teflon is avoided, an uneventful postoperative course can be expected.

Comparison of functional endoscopic sinus surgery under local and general anesthesia.

We present a retrospective comparison of intravenous sedation and general anesthesia techniques employed at New York University-Bellevue Medical Center for functional endoscopic sinus surgery. Some authors have stressed the use of local anesthesia with intravenous sedation in order to avoid complications and reduce blood loss. We have reviewed 232 patients who underwent 401 consecutive ethmoidectomies and maxillary antrostomies. Local anesthesia, employed in 64% of patients, carried an estimated blood loss of 23 mL per side. General anesthesia was associated with an average blood loss of 58 mL per side. The rate of operative complications for local anesthesia was 8.7% per patient, with a 1.6% rate of major complications per side. General anesthesia carried an overall complication rate of 2.4% per patient, with no major complications. General anesthesia is a relatively safe and viable option for endoscopic sinus surgery that in selected cases may be preferable to local anesthesia.
