BACKGROUND AND OBJECTIVES: Ultrasound-guided subsartorial saphenous nerve block is commonly used to provide complete surgical anesthesia of the foot and ankle in combination with a popliteal sciatic nerve block. However, in part owing to its small caliber and absence of a prominent vascular landmark in the subsartorial plane distal to the adductor canal, the saphenous nerve is more difficult to reliably block than the sciatic nerve in the popliteal fossa. Although the saphenous nerve is a sensory nerve only, neurostimulation can be used to elicit a "tapping" sensation on the anteromedial aspect of the lower leg extending toward the medial malleolus...

: Local anaesthetic injection between the tibial and commmon peroneal nerves within connective tissue sheath results in a predictable diffusion and allows for a reduction in the volume needed to achieve a consistent sciatic popliteal block. Using 3D ultrasound volumetric acquisition, we quantified the visible volume in contact with the nerve along a 5cm segment. METHODS: We included 20 consecutive patients scheduled for bunion surgery. Ultrasound guided popliteal block was performed using a posterior, out of plane approach at the level of división of the sciatic nerve...

BACKGROUND: Scarf osteotomy has been used in hallux valgus surgery due to its large fixation surface for screws and low postoperative complications. However, screws may cause skin irritation from their head, which may require an additional surgical procedure to remove. METHODS: This study included 115 patients (106 females and 9 males, 115 feet) who underwent hallux valgus correction with a scarf osteotomy using bioabsorbable screws between September 2010 and September 2012...

OBJECTIVE: Necrotizing fasciitis is an infection of the soft tissue that is characterized by rapidly spreading inflammation and subsequent necrosis. It is a rare complication of peripheral nerve blocks. We report a rare case of necrotizing fasciitis after placement of a peripheral nerve catheter. CASE REPORT: A 58-year-old woman presented for an elective right second metatarsal resection and received a sciatic nerve catheter for postoperative pain control. On postoperative day 7, clinical examination and imaging supported the diagnosis of necrotizing fasciitis...

Because of its rapid onset time, recent years have seen an increase in the use of ultrasound (US)-guided popliteal sciatic nerve block (PSNB) via subparaneural injection for induction of surgical anesthesia. Moreover, in below-knee surgery, combined blocks, as opposed to sciatic nerve block alone, have become more common. These combined blocks often require a large volume of local anesthetic (LA), thus increasing the risk of local-anesthetic systemic toxicity (LAST). Thus, to decrease the risk of LAST, it is important to know the minimum effective volume (MEV) required for an adequate block...

The adductor canal block has become a common analgesic technique in patients undergoing knee arthroplasty. Dispersion of local anesthetic outside the adductor canal through interfascial layers and blockade of smaller nerves that confer innervation to the knee could contribute to the analgesic efficacy of the adductor canal block. We studied the diffusion of local anesthetic mixed with dye after injection into the adductor canal in fresh human cadavers. In all 8 legs, injectate was found in the popliteal fossa in contact with the sciatic nerve and/or popliteal blood vessels...

Diabetic foot ulcer is the most common cause of diabetes-associated nontraumatic lower extremity amputation. Most patients who undergo lower extremity amputation for a diabetic foot have had diabetes for a long time and suffer from multiorgan disorder; thus, it can be a challenge to ensure sufficient anesthetic and analgesic effects while maintaining stable hemodynamics. Recently, peripheral nerve block has gained popularity owing to its attenuating effects of systemic concerns. This retrospective observational study aimed to compare the effects of remifentanil-based general anesthesia (GEA) and popliteal nerve block (PNB) on postoperative pain and hemodynamic stability in diabetic patients undergoing distal foot amputation...

Although regional anaesthesia is a commonly preferred anaesthesia technique for pregnant patients undergoing non-obstetric surgery, peripheral nerve blocks are relatively less administered. The use of popliteal sciatic nerve block for foot-ankle surgery has been presented for a nulliparous parturient at 32 weeks of gestation scheduled to undergo surgical exploration of an arterial pseudoaneurysm on her right plantar surface due to a penetrating stab injury. Since surgery did not require pneumatic tourniquet, the sciatic nerve was blocked via the popliteal approach with a single shot injection of 30 mL of 0...

Raynaud's syndrome has been treated medically and invasively, sometimes with regional anesthesia leading up to sympathectomy. We demonstrate that regional anesthesia was in this case a useful technique that can allow some patients to find temporary but significant relief from symptoms of Raynaud's syndrome exacerbation. We present a 43-year-old woman with Raynaud's syndrome secondary to lupus who was treated with bilateral popliteal nerve block catheters for ischemic pain and necrosis of her feet; this led to almost immediate resolution of her pain and return of color and function of her feet...

A cross-sectional survey study on French practice in ultrasound-guided regional anesthesia was carried out. A questionnaire (demographic data, assessment of the likely benefits of ultrasonography, and its use in daily practice: blocks and hygiene) was emailed to all members of the French-speaking association of anesthesiologists involved in regional anesthesia. The questionnaire was filled out and returned by 634 experienced anesthesiologists. An ultrasound machine was available in 94% of cases. Ultrasound-guided regional anesthesia has become the gold standard technique for three-quarters of responders...

BACKGROUND: Even as the use of peripheral nerve blockade in the perioperative setting is increasing, neural injury secondary to accidental intraneural injection remains a significant patient safety concern. Current modalities, including electrical stimulation and ultrasound imaging, still lack consistency and absolute reliability in both the detection and prevention of this complication. The measurement of electrical impedance (EI) could be an easy and valuable additional tool to detect intraneural needle placement...

BACKGROUND AND OBJECTIVES: This prospective, randomized, double-blind study compared the effects of the ultrasound-guided popliteal sciatic nerve block performed by either intraneural or subparaneural approach followed by an electrophysiological evaluation. We hypothesized that intraneural injection provides a faster onset with a better success rate compared with the subparaneural approach. METHODS: Eighty-eight patients were enrolled and randomized to receive an ultrasound-guided popliteal sciatic nerve block injecting 15 mL ropivacaine 1% according to an intraneural injection (group INTRA = 44) or a subparaneural injection (group SUBPARA = 44)...

BACKGROUND AND AIMS: A popliteal block is effective in managing postoperative pain for foot surgery, but since the duration of analgesia is limited following a single-shot popliteal fossa block technique, methods to prolong effective postoperative analgesia are mandatory. The aim of this study was to assess the effect of adjuvants to ropivacaine on the duration of sensory and motor block. METHODS: In this double-blind randomized placebo-controlled study, we evaluated the analgesic effect of clonidine or dexamethasone (DXM) when added to ropivacaine for hallux valgus surgery...

An 82-year-old woman who had received two operations for lumbar spinal stenosis was treated successfully for persistent nocturnal leg cramps with lumbar sympathetic ganglion block. The stent in the right popliteal artery improved cramps again following the recurrence one month after the block. The head up position in bed against gastroesophageal reflux was found injurious at the time of second recurrence one year after stenting. After the correction of lying position, her legs were in good condition for over one year...

Pain management is extremely important in day surgery, and it is one of the limiting factors for this type of procedures. Locoregional anesthesia is strongly recommended for day surgery; nevertheless, it could be very difficult to localize nerve position especially in obese patients. Furthermore, a complete nerve blockade could result in a delayed discharge. We present a case of analgesic ultrasound-guided block of tibial and common peroneal nerves in the popliteal fossa without any motor function involvement in an obese patient undergoing debridement of an infected lower limb ulcer; all previous attempts of surgical debridement in day surgery with topical anesthetics had failed because of discomfort due to pain...
