Clinical Trial – Effect of Bilateral Quadratus Lumborum Block for Pain Relief in Patients With Cesarean Section
Cesarean section commonly induces moderate to severe pain for 48 hours. These patients have
additional compelling reasons to provide adequate pain relief as early mobilization is a key
factor to prevent the risk of thromboembolic event which is increased during pregnancy.
Beside these, patients need to be pain free to takecare for their newborn and breastfeed
them. Poorly controlled pain after cesarean section also increases risk of chronic pain and
postpartum depression.
Intrathecal morphine is considered the "gold standard" for postoperative pain relief after
cesarean delivery. The duration of analgesic effect of morphine extend to 12-24 hours. Its
widespread use is due to its favorable pharmacokinetic profile, ease of administration and
low cost. Although intrathecal morphine is highly effective, its use is associated with
undesirable adverse effect particularly nausea, vomiting and pruritus which reduce overall
patients’ satisfaction. More serious complication is the risk of delayed maternal respiratory
depression.
The Quadratus Lumborum block was first described in 2007 which demonstrates a spread to the
paravertebral space, thus leads to a more extensive block to T5-L1 nerve branches and a long
lasting block with the potential to provide visceral pain relief. Therefore, this block has
an evolving role in postoperative analgesia for many lower abdominal surgeries. As the safety
is concerned, there has been one report of a patient with unilateral hip flexion and knee
extension weakness leading to unplanned overnight admission following lateral quadratus
lumborum block after laparoscopic gynaecological operation.
If the result favors effective, it will have the advantage of a combination with intrathecal
opioid to prolong the pain free period after cesarean section which has about 4,000 cases per
year.
[Cerebral injury induced by heat stroke and the therapeutic effect of hyperbaric oxygen therapy].
Abstract: With the global warming, the incidence of heat stroke was significantly higher than before. Severe heat stroke has a high mortality, high morbidity and consolidated central nervous system injury characteristics. The main features of severe heat stroke...
Hyperbaric oxygen therapy for children with autism spectrum disorder.
As autism spectrum disorder (ASD) is a multifactorial condition, with genetic and environmental risk factors contributing to children’s unique presentation and symptom severity, a range of treatments have been suggested. Parents of children with ASD in my clinic are asking me about alternative therapies to improve their children’s condition. One of those therapies is hyperbaric oxygen therapy (HBOT); commercial advertisement in the past has suggested good results with this approach. Should I recommend the use of HBOT for children with ASD? Answer Hyperbaric oxygen therapy provides a higher concentration of oxygen delivered in a chamber or tube containing higher than sea level atmospheric pressure.
