Adrenaline, Orthopedic, Post-Dural Puncture Headache, Randomized Controlled Study, Sphenopalatine Ganglion Block
Conditions
Brief summary
The aim of this study is to assess the efficacy, onset and duration of analgesia of sphenopalatine ganglion bock (SPGB) using lidocaine 4% with adrenaline as a treatment of postoperative Post dural puncture headache (PDPH) of orthopedic patients after lower limbs surgeries.
Interventions
Sphenopalatine Ganglion Block will be performed by a transnasal approach. Few drops of lidocaine 2% will be instilled into both anterior nares. Then a cotton-tipped applicator soaked in 4% lignocaine & adrenaline (1 to 200000 will be passed through both the nares and the end of the applicator tip will be positioned just superior to the middle turbinate and anterior to the pterygopalatine fossa and sphenopalatine ganglion for 5 min with the patient in the supine position.
Patients will receive paracetamol 1 gm 6 hours daily intravenously for a day. If adequate pain relief will not be achieved, intravenous diclofenac 75 mg twice daily will be added.
