BACKGROUND AND OBJECTIVES Postoperative analgesia after hepatectomy remains a challenge, mainly because of limited therapeutic index of the conventional opioids. The aim of this study is to evaluate the efficacy of bilateral single-site thoracic paravertebral block for the management of postoperative pain following right lobe donor hepatectomy (RLDH) using a prospective, randomized and controll...

BACKGROUND AND OBJECTIVES Lidocaine could provide many advantages in continuous regional anesthesia techniques, including faster onset, greater titratability, and lower cost than long-acting local anesthetics. This prospective, randomized, double-blinded, pilot study is therefore intended to compare lidocaine to ropivacaine in bilateral continuous paravertebral blocks using a multimodal approac...

BACKGROUND Animal and volunteer studies indicate that ropivacaine is associated with less neurologic and cardiac toxicity than bupivacaine. Ropivacaine may offer advantages when used for thoracic paravertebral block. This study was designed to describe the pharmacokinetics of ropivacaine after thoracic paravertebral block. METHODS Twenty female patients undergoing elective unilateral breast s...

Background Paravertebral catheters are generally inserted and removed without complications. However, catheter breakage occurs rarely. This is the first report describing breakage of a thoracic paravertebral catheter and retention of the catheter fragment within the patient. Case presentation A 65-year-old female patient complained of an unusual sensation in her back during postoperative chem...

STUDY DESIGN Animal model study. PURPOSE The purpose of this study was to evaluate the histological variation in the injured muscle and production of calcitonin gene-related peptide in rats over time. OVERVIEW OF LITERATURE Vertebral surgery has been reported to cause atrophy of the back muscles, which may result in pain. However, few reports have described the time series histological vari...

BACKGROUND AND AIMS Paravertebral block, pectoral nerve (Pecs) block and wound infiltration are three modalities for post-operative analgesia following breast surgery. This study compares the analgesic efficacy of these techniques for post-operative analgesia. METHODS Sixty-five patients with American Society of Anesthesiologists' physical status 1 or 2 undergoing modified radical mastectomy ...

A six year old female child, weighing 13 kg was posted for patent ductus arteriosus ligation by a left lateral thoracotomy approach. The planned anesthetic was general anesthesia and placement of a continuous paravertebral block at the end of surgery for post operative analgesia. The patient was induced with propofol 30 mg i.v, fentanyl citrate 25 μg i.v and atracurium 7 mg i.v to facilitate en...
