We present the case of a 65-year-old man with latent thiamine deficiency who manifested lower limb neuropathy after receiving spinal anesthesia. We discuss our care of this patient and include a discussion of thiamine deficiency generally, its possible origins, symptoms, and recommended techniques for treatment of these patients.

Patients undergoing major knee surgery may experience postoperative pain, which could be exacerbated by early postoperative continuous passive motion or active mobilization. This pain may result in poor functional recovery. Use of regional analgesia techniques to achieve more consistent pain relief and to facilitate rapid rehabilitation can play an important role in optimizing postoperative outcome after anterior cruciate ligament repair (ACLR). This case study concerns a 20-year-old male soldier, otherwise healthy, who underwent ACLR. We inserted a catheter in the fascia iliaca compartment and performed postoperative analgesia with low-concentration ropivacaine by using an elastomeric pump. The patient started early rehabilitation under fascia iliaca compartment analgesia. We discuss the case and the influence of regional analgesia techniques on postoperative and clinical outcomes.
A 51-year-old ASA physical status II, non-insulin-dependent diabetic male patient manifested lower limb nerve injury after receiving postoperative epidural analgesia with ropivacaine 0.2%. The case is presented, including a discussion of the relation between local anesthetic toxicity and diabetic neuropathy.

OBJECTIVES: The objective of this case report is to describe a femoral nerve injury after a psoas compartment block (PCB) and to discuss the probable mechanisms of injury and neuron regeneration. To date, this is the first report of severe femoral nerve injury after PCB. CASE REPORT: A 60-year-old, American Society of Anesthesiologists II woman underwent right total knee replacement under general anesthesia and continuous PCB for postoperative analgesia. Postoperatively, she showed signs of severe femoral nerve injury. A physical therapy program and muscle electrical stimulation were instituted and continued for 6 months. The patient recovered completely with no residual motor or sensory deficit and had no other complication. CONCLUSIONS: Severe nerve injuries after regional anesthesia techniques remain infrequent and probably unreported. Our case report suggests that severe femoral nerve injury should be added to the list of reported complications during PCB. This case report is also encouraging because it shows the possibility of a good recovery after such injury.
