A case of an infant who had morphine exposure during and following pregnancy while her mother was treated with intrathecal (i.t.) morphine is presented along with a review of the relevant literature. Successful maternal pain management was achieved during pregnancy and while breastfeeding. Minimal maternal serum and breast milk levels in the first 7 postpartum weeks were found. Also, infant sleep and arousal behavior and general development at 2 and 7 months were unremarkable, illustrating the possible safe and efficacious use of i.t. morphine during and following pregnancy. Further work is required to understand opioid pharmacology during breastfeeding, which will be used to develop an empirical approach to breastfeeding and morphine use.

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
