Parasympathetic Pathway

Lung inflation is known to produce reflex relaxation of tracheal smooth muscle (TSM) and dilation of the upper airway, but the specific efferent pathway involved has not been established. Therefore we examined TSM tone in four trained awake dogs by measuring pressure changes in the water-filled cuff of an endotracheal tube that was inserted into the lower cervical trachea through a permanent tracheostomy. Under control conditions, sustained lung inflation with 1 liter of air produced apnea (Hering-Breuer inflation reflex) and a decrease in cuff pressure (Pcuff) of 37.4 +/- 12.0 (mean +/- SD) cmH2O. beta-Adrenergic blockade with propranolol had no effect on either the apneic or TSM responses to lung inflation. Efferent parasympathetic blockade with atropine sulfate (1.2–2.4 mg) abolished TSM tone, which was then restored to control levels by a continuous intravenous infusion of serotonin (14–28 micrograms X kg-1 X min-1). Under these conditions, lung inflation still induced reflex apnea but no longer relaxed TSM tone (mean decrease in Pcuff, 2.7 +/- 1.4 cmH2O, P less than 0.001). The findings indicate that reflex tracheal dilation in response to lung inflation is mediated by an efferent cholinergic (parasympathetic) pathway.

The Relationship

Abstract The aim is to describe an ultrasound procedure that evaluates the prevertebral soft tissue (PST) and upper airway and investigate the compatibility between X-ray and ultrasonography in PST evaluation. We included 11 radiculopathy/myelopathy patients who underwent anterior cervical decompression and fusion involving C5/6, C6/7, or both segments. The condition of the PST and upper airway was evaluated over 14 days. The Bland–Altman method was used to evaluate the degree of agreement between the PST values obtained using radiography versus ultrasonography. The Pearson correlation coefficient was used to determine the relationship between the PST measurement methods. Single-level anterior cervical decompression and fusion (ACDF) was performed in 8 cases and double-level ACDF, in 3 cases. PST and upper airway thickness peaked on postoperative day 3, with no airway complications. The Bland–Altman bias was within the prespecified clinically nonsignificant range—0.13 ± 0.36 mm (95%CI 0.04–0.22 mm). Ultrasonography effectively captured post-ACDF changes in PST and upper airway thickness and detected airway edema. Ultrasonography can help continuously assess the PST and upper airway as it is simple and has no radiation exposure risk. Therefore, radiography alone is insufficient for post-ACDF detection of airway complications and including ultrasonography may be beneficial.

Intubation Success

The aim of this study is to compare the hemodynamic responses, durations of intubation, intubation success rates and postoperative upper airway complications between the intubation performed with direct laryngoscopy and blind intubation performed with LMA-Fastrach application in normotensive patients. This present study was performed with the approval of ethical committee and in the surgery rooms between the date March 2010-August 2010. The study was performed on 80 patients aged between 18 and 60 and had American Anesthetists Assosiation (ASA) classification I-II. Endotracheal intubation was essential in their elective abdomen surgeries. The patients were divided into 2 groups as ILMA-Fastrach Group (Group I, n=40) and laryngoscopy group (Group L, n=40). 80 patients aged between 18 and 60. Of those, 54 (67.5%) were female and 26 (32.5%) were male. The age average of the patients was 46.3 ± 10.7. There was not a statistically significant difference between the demographic parameters of the patients. When compared to the onset value of SAP in Group I and Group L, a statistically significant difference was not detected in the groups in terms of SAP 1st minute and 5th minute values. When compared to the SAP onset value of the cases, the decrease in the 1st minute was statistically significant and when compared to the 1st minute value, the decrease in the 5th minute was not statistically significant. In the groups, a statistically significant difference was not observed in terms of DAP outset 1st and 5th minute values. When compared to the DAP onset value of the patients in Group L, the increase in the 1st minute was statistically significant. When compared to the 1st minute value, the decrease in the 5th minute was statistically significant. When compared to the onset value of MAP in Group L, the increase in the 1st minute was statistically significant. In terms of HR onset 1st and 5th minute values a statistically significant value was not detected. In conclusion, patients performed endotracheal intubation with LMA-Fastrach was more stabile than the ones intubated with direct laryngoscopy in terms of hemodynamics. Fewer complications were observed in LMA-Fastrach group and there was not any difference in terms of success rates.
