BACKGROUND: Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck. CASE REPORT: We present a patient with an ipsilateral transient Horner syndrome after ultrasound guided single shot of 15mL 0...

BACKGROUND: Rib fractures are commonly encountered in the setting of trauma. The aim of this study was to assess the association between the clinical outcome of rib fracture and epidural analgesia (EA) versus paravertebral block (PVB) using the National Trauma Data Bank (NTDB). METHODS: Using the 2011 and 2012 versions of the NTDB, we retrieved completed records for all patients above 18 years of age who were admitted with rib fractures. Primary outcome was in-hospital mortality...

Hypnosis has been proven to be a powerful tool in the management of anxiety and pain. It allows for an increase of pain threshold, which can reach the level of surgical analgesia. Recently injection of local anesthetics around the serratus muscle has been presented as an alternative to paravertebral block for cancer breast surgery. We report the successful use of hypnosis in combination with an axillary compartment block for lumpectomy and axillary lymph node dissection.

BACKGROUND: Although thoracic paravertebral block (TPVB) is recommended in major breast surgery, there is no gold standard to assess the success of TPVB. Pupillary dilation reflex (PDR) is the variation of the pupillary diameter after a noxious stimulus. The objective was to evaluate the feasibility of recording the PDR to assess analgesia in an anesthetized thoracic dermatome after TPVB. METHODS: This prospective, observational, single-center study included 32 patients requiring breast surgery under general anesthesia and TPVB...

OBJECTIVE: To compare the motor and sensory block efficacy and duration of a modified paravertebral brachial plexus block (PBPB) after administration of lidocaine alone (LI) or combined with epinephrine (LE). STUDY DESIGN: Prospective, randomized, blinded, crossover study. ANIMALS: A total of eight healthy female Beagle dogs. METHODS: Under general anesthesia, modified PBPB was performed on the left thoracic limb using neurostimulation and/or ultrasound guidance to administer lidocaine (2 mg kg(-1); 0...

Advantages of thoracic paravertebral analgesia (TPA) include placement of the catheter closer to the surgical field; however, the catheter can become damaged during the operation. We experienced a case of intraoperative TPA catheter breakage that prompted us to perform an experiment to investigate possible causes. A 50-year-old male underwent a thoracoscopic lower lobectomy under general anesthesia with TPA via an intercostal approach. Following surgery, it was discovered that the catheter had become occluded, as well as cut and fused, so we reopened the incision and removed the residual catheter...

PURPOSE: Thoracic paravertebral block (TPVB) may be an alternative to thoracic epidural analgesia. A detailed knowledge of the anatomy of the TPV-space (TPVS), content and adnexa is essential in understanding the clinical consequences of TPVB. The exploration of the posterior TPVS accessibility in this study allows (1) determination of the anatomical boundaries, content and adnexa, (2) description of an ultrasound-guided spread of low and high viscous liquid. METHODS: In two formalin-fixed specimens, stratification of the several layers and the 3D-architecture of the TPVS were dissected, observed and photographed...

Breast surgery is frequently associated with postoperative pain, nausea and vomiting, that result in increased patient's suffering, prolongation of hospital stays and related costs. Thoracic paravertebral nerve block (TPVB) is a viable option to the classic multimodal analgesia in breast surgery as it enhances surgical anesthesia and postoperative analgesia. In this review, we report the results of a number of studies on the role of TPVB in breast surgery. This technique is associated with a superior control of the pain, a reduction in opioids consumption after surgery, a decrease in postoperative nausea and vomiting, and an overall decrease in length of hospital stay...

PURPOSE: Retrospective studies have associated perioperative regional anesthesia/analgesia during mastectomy for breast cancer with a decreased incidence of cancer recurrence. However, to date, no prospective data from a randomized controlled trial have been reported. In a previous study we found that extending a single-injection paravertebral block with a multiple-day perineural local anesthetic infusion improves analgesia. This follow-up study investigates the rates of cancer recurrence for the single-injection and multiple-day infusion treatments...

BACKGROUND: Of all the postsurgical pain conditions, thoracotomy pain poses a particular therapeutic challenge in terms of its prevalence, severity, and ensuing postoperative morbidity. Multiple pain generators contribute to the severity of post-thoracotomy pain, and therefore a multimodal analgesic therapy is considered to be a necessary strategy. Along with opioids, thoracic epidural analgesia, and paravertebral blocks, N-Methyl-D-Aspartate (NMDA) receptor antagonists such as ketamine have been used as adjuvants to improve analgesia...

INTRODUCTION: Aberrant, altered, or blocked lymphatic drainage may contribute to the high recurrence rate of breast cancer. Thus, an efficient evaluation of lymphatic drainage from the breasts and/or upper limbs is essential in the management of lymphedema and in ipsilateral primary or contralateral recurrent breast cancer patients. There are very few reports of lymphatic drainage to the paravertebral lymph nodes in patients with a lymphedema after breast cancer surgery with or without reconstruction...

In this case report, the serratus anterior plane block was used in conjunction with multilevel continuous thoracic paravertebral blocks (TPVB) and general anesthesia in 3 thoracotomy cases. All blocks were accompanied by use of catheters that allowed continuous local anesthetic infusions and intermittent local anesthetic bolus injections to address postoperative pain. In all 3 patients, the serratus anterior plane block provided analgesia for chest tube-related pain that was not provided by the TPVB alone.

The purpose of this study was to investigate whether continuous paravertebral block at levels T1 and T2 with bupivacaine infusion can improve the survival of free flaps in maxillofacial reconstruction. The study was designed as a randomized controlled trial and included 36 adult patients scheduled for maxillofacial free flap reconstruction under general anesthesia. Patients were randomly divided into two groups: patients in group A received continuous paravertebral block at levels T1 and T2, while patients in group B served as controls...

BACKGROUND: The spread of injectate resulting from a transmuscular quadratus lumborum (TQL) block and a transverse oblique paramedian (TOP) TQL block has never been examined. The aim of this cadaveric study was to investigate by which pathway the injectate spreads cephalad into the thoracic paravertebral space and which nerves were dyed by the injectate cephalad and caudad to the diaphragm when performing a TQL and a TOP TQL block. We also aimed to investigate whether the thoracic and lumbar sympathetic trunks as well as the lumbar plexus were covered by the injectate...

Postoperative pain after bariatric surgery can be significant and yet difficult to manage. These patients frequently have associated obstructive sleep apnea and are at risk of respiratory depression with opioid analgesia. Abdominal wall blocks such as the subcostal transversus abdominis plane block are not of significant benefit, probably in part because they provide only somatic analgesia. The ultrasound-guided erector spinae plane (ESP) block is a recently described regional anesthetic technique for providing thoracic analgesia when performed at the level of the T5 transverse process...

The autonomic nervous system is composed of the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is implicated in situations involving emergent action by the body and additionally plays a role in mediating pain states and pathologies in the body. Painful conditions thought to have a sympathetically mediated component may respond to blockade of the corresponding sympathetic fibers. The paravertebral sympathetic chain has been targeted for various painful conditions. Although initially injected using landmark-based techniques, fluoroscopy and more recently ultrasound imaging have allowed greater visualization and facilitated injections of these structures...
