Anesthesiology and pain medicine
-
Pain following laparoscopy could be due to different causes requiring effective postoperative analgesia. ⋯ Intraperitoneal Infiltration of bupivacaine with meperidine following surgery provided more appropriate analgesia after gynecologic diagnostic laparoscopy than administration of IV paracetamol.

Nerve damage after regional anesthesia has been of great concern to anesthetists. Various modalities have been suggested to recognize and prevent its incidence. An understudied area is the measurement of intraneural pressure during peripheral nerve blockade. Previous investigations have produced contradicting results with only one study being conducted on human cadavers. ⋯ Obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. Intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. Peripheral nerves "pressure mapping" hypothetically might show difference amongst various nerves depending on anatomic location, histologic structure, and ultrasonographic appearance.

The use of Propofol often results in pain upon injection, which is sometimes very distressing for patients. Many patients report some degree of pain or discomfort on injection with propofol. Injection-induced pain during induction of anesthesia can result in patient's discomfort. ⋯ Nitroglycerine may be a safe and effective adjuvant therapeutic for pain reduction in patients under propofol injection. Hence, its use for reduction of propofol injection-induced pain is recommended.

Arthroscopic knee surgery is commonly performed as an outpatient procedure and is often associated with postoperative pain. ⋯ Intra-articular levobupivacaine-tenoxicam-morphine combination provides effective pain relief, longer analgesic duration, and less analgesic requirement when compared with intra-articular levobupivacaine-tenoxicam-tramadol combination and saline after knee arthroscopic surgery.
