[Anaesthetic preoperative assessment of chronic medications and herbal medicine use: a multicenter survey].

OBJECTIVE: This study was undertaken to quantify the use of chronic medication and herbal remedies in the presurgical population. STUDY DESIGN: Prospective multicenter survey. PATIENTS AND METHODS: Adult patients presenting for anaesthesia were directly asked if they were currently using chronic medication or herbal remedies. RESULTS: Among 1057 patients (age 54+/-17 yrs, woman 54%, ASA 2 [1-4], 74%) were taking one or more chronic medication. The most commonly used treatments were, in descending order angiotensin-converting enzyme inhibitors and angiotensin-II receptor blockers (15%), beta blockers (11%) and platelet inhibitors (10%). Also, 9% were taking one or more of the following herbal remedies known to interact with the perioperative period: valeriane, ginseng, ginkgo, St John's wort, echinacea and ephedra. Women and patients aged 40-70 yr were most likely to be taking a herbal product (p<0.001 and p<0.01 respectively). CONCLUSION: Chronic medication and herbal remedies are common in patients presenting for anaesthesia. Because of the potential interactions between anaesthetic drugs or techniques and such medication it is important for anaesthetists to be aware of their use.

Randomized study comparing the "sniffing position" with simple head extension for laryngoscopic view in elective surgery patients.

BACKGROUND: The "sniffing position" is recommended for optimization of glottic visualization under direct laryngoscopy. However, no study to date has confirmed its superiority over simple head extension. In a prospective, randomized study, the authors compared the sniffing position with simple head extension in orotracheal intubation. METHODS: The study included 456 consecutive patients. The sniffing position was obtained by placement of a 7-cm cushion under the head of the patient. The extension position was obtained by simple head extension. The anesthetic procedure included two Laryngoscopies without paralysis: the first was used for topical glottic anesthesia. During the second direct laryngoscopy, intubation of the trachea was performed. The head position was randomized as follows: group A was in the sniffing position during the first Laryngoscopy and the extension position during the second, group B was in the extension position during the first laryngoscopy and the sniffing position during the second. Glottic exposure was assessed by the Cormack scale. RESULTS: The sniffing position improved glottic exposure (decreased the Cormack grade) in 18% of patients and worsened it (increased the Cormack grade) in 11% of patients, in comparison with simple extension. The Cormack grade distribution was not significantly modified between the two groups. Multivariate analysis showed that reduced neck mobility and obesity were independently related to improvement in laryngoscopic view with application of the sniffing position. CONCLUSIONS: Routine use of the sniffing position appears to provide no significant advantage over simple head extension for tracheal intubation in this setting. The sniffing position appears to be advantageous in obese and head extension-limited patients.
