Objective: In our study, the effect of intravenous magnesium sulphate in normal and pre-eclamptic patients on spinal anaesthesia produced by bupivacaine was investigated.

Methods: Sixty-four pregnant (32 normal and 32 pre-eclamptic) were accepted in this study. Pregnants were divided into four groups as patients given intravenous magnesium sulphate and as control.

Coadministration of intravenous remifentanil and morphine for post-thoracotomy pain: comparison with intravenous morphine alone.

Objectives: In this double-blind, randomized study, the authors compared the effects of a patient-controlled remifentanil and morphine combination with morphine alone on post-thoracotomy pain, analgesic consumption, and side effects.

Design: A prospective, randomized, double-blind clinical study.

Setting: University hospital.

The Comparison of Patient-Controlled Remifentanil Administered by Two Different Protocols (Bolus and Bolus+Infusion) and Intramuscular Meperidine for Labor Analgesia.

Objective: Nowadays, there are many pain relief methods for reducing the pain and stress of labor and delivery. In our study, two different remifentanil protocols (bolus and bolus+infusion) administered by patient-controlled analgesia method were compared with intramuscular meperidine for labor analgesia.

Methods: Ninety parturients who were scheduled for vaginal delivery were included in this study.

A comparative study on the effects of intrathecal morphine added to levobupivacaine for spinal anesthesia.

Objective: In this prospective, randomized, double-blind, controlled study, we investigated the sensory, motor, and analgesic block characteristics oftwo diferent doses of morphine compared with saline when added to 0.5 percent levobupivacaine.

Design: Prospective, randomized, double-blinded, controlled study.

Comparison of effects of ketamine, ketamine-dexmedetomidine and ketamine-midazolam on dressing changes of burn patients.

Objective: The aim of this randomized, controlled study was to compare the sedoanalgesic effects of ketamine-dexmedetomidine and ketamine-midazolam on dressing changes of burn patients.

Materials And Methods: Following Ethics Committee approval and informed patient consent, 90 ASA physical statuses I and II adult burn patients were included in the study. Patients were randomly divided into three groups.

Epidural ropivacaine versus ropivacaine plus tramadol in postoperative analgesia in children undergoing major abdominal surgery: a comparison.

Purpose: In this study, we aimed to compare the effects of ropivacaine alone and ropivacaine plus tramadol administered epidurally for postoperative analgesia in children.

Methods: Following Ethics Committee approval and informed parent consent, 44 children aged between 2 and 12 years, with ASA physical status I or II, who were undergoing major abdominal surgery were included in the study. Following tracheal intubation, patients were placed into lateral decubitus position and an epidural catheter (22-24 G) was inserted by using a Tuohy needle.

Comparison of the effect of adding remifentanil to patient-controlled tramadol or morphine for postoperative analgesia after major abdominal surgery.

Objective: In this study, the authors investigated the effect of the addition of remifentanil to tramadol or morphine for patient-controlled analgesia (PCA).

[Effect of ondansetron in lower extremity bone surgery on morphine and tramadol consumption using patient controlled analgesia].

In this study, we aimed to assess the effect of administration of ondansetron on morphine and tramadol consumptions. After approval by the ethics committee, 120 patients with ASA status I or II, who will undergo elective lower extremity surgery, were included in the study. Patients were randomly divided into 4 groups following the anesthesia induction.

[Comparison of ropivacaine, ropivacaine plus tramadol and ropivacaine plus morphine in patients undergoing minor hand surgery].

In our study we aimed to compare the effects of ropivacaine alone, ropivacaine plus tramadol HCl, and ropivacaine plus morphine HCl used as intravenous regional anesthesia (IVRA), on duration to the initiation of analgesia, total analgesia time, analgesic requirement, sedation levels and hemodynamic parameters. 53 patients undergoing minor hand surgery were included into the study. Patients were randomly divided into three groups to receive 40 ml of ropivacaine 0.

[Effect of tramadol on regeneration after experimental sciatic nerve injury].

Abnormal impulses in peripheral nerves play a critical role in neuropathic pain syndromes. The voltage-gated Na+ channels that underlie the action potential are main targets for clinically useful drugs in the pain therapy. Systemic tramadol has been shown to have clinical efficacy against some forms of neuropathic pain.

Safe and effective sedation and analgesia for bone marrow aspiration procedures in children with alfentanil, remifentanil and combinations with midazolam.

Background: Invasive procedures such as bone marrow aspiration in children may be painful and cause anxiety. We investigated the efficacy and safety of remifentanil (R) alfentanil (A), remifentanil-midazolam (RM), and alfentanil-midazolam (AM) combinations in providing analgesia and sedation for bone marrow aspiration.

Methods: Eighty children undergoing a diagnostic bone marrow aspiration whose ages ranged from 5-16 years (mean 9.

[Cyclooxygenase-2 inhibitors in postoperative pain management].

Management of acute postoperative pain remains suboptimal; nearly 80 % of the patients report moderate to extreme pain following surgery. Nonselective nonsteroidal antiinflammatory drugs (NSAIDs) have a role in postoperative pain management, but conventional NSAIDs can cause gastrointestinal ulceration, renal injury, and disruption of platelet function and hemostasis. Recently, cyclooxygenase-2 (COX-2) specific inhibitors such as rofecoxib and celecoxib were developed to provide the increased efficacy of non-specific NSAIDs while limiting associated side effects.
