Dexamethasone added to local lidocaine for infiltration along the spinal-epidural needle pathway decreases incidence and severity of backache after gynecological surgery.

Background: The aim of this study was to evaluate the effect of dexamethasone added to local lidocaine infiltration on incidence and severity of backache after combined spinal-epidural anesthesia for gynecological surgery.

Material And Methods: We randomly allocated 160 patients to receive either local lidocaine infiltration along the pathway of the spinal-epidural needle (Group L) or local dexamethasone and lidocaine infiltration (Group DL). The incidence and scores for back pain were evaluated on the first, second, and third day (acute lumbago) and first, second, and sixth month (chronic lumbago) after surgery.

Effect of Therapeutic Hypercapnia on Inflammatory Responses to One-lung Ventilation in Lobectomy Patients.

Background: One-lung ventilation (OLV) can result in local and systemic inflammation. This prospective, randomized trial was to evaluate the effect of therapeutic hypercapnia on lung injury after OLV.

Method: Fifty patients aged 20 to 60 yr undergoing lobectomy were randomly provided with air or carbon dioxide (partial pressure of carbon dioxide: 35 to 45 mmHg or 60 to 70 mmHg).

Local airway anesthesia attenuates hemodynamic responses to intubation and extubation in hypertensive surgical patients.

Background: The aim of this study was to evaluate the effects of topical ropivacaine anesthesia on hemodynamic responses during intubation and extubation of hypertensive patients.

Material And Methods: One hundred fifty patients with hypertension ASA II-III were scheduled for noncardiac operations. Patients were divided into 3 groups: a control group receiving 5 ml saline, and 2 groups receiving topical anesthesia with 100 mg lidocaine or 37.

Ropivacaine plus dexamethasone infiltration reduces postoperative pain after tonsillectomy and adenoidectomy.

Objective: To compare the effect of ropivacaine plus dexamethasone and ropivacaine alone as infiltration anesthesia on postoperative pain, nausea and vomiting, and oral intake in children after tonsillectomy and adenoidectomy.

Methods: Two hundred pediatric patients scheduled for tonsillectomy and adenoidectomy were prospectively enrolled and randomly placed in a ropivacaine with dexamethasone group (RD) or a ropivacaine alone group (R). Treatment for both groups was administered by local infiltration, and pain scores were recorded at various intervals.
