A woman pulled a clump of hair out of a paramedic's head and attacked another with a blade after flagging down an ambulance.
Yasmin Punshon assaulted two paramedics and two police officers in the early hours of Saturday, April 24 in Middlesbrough.
The 24-year-old appeared at Teesside Magistrates' Court to be sentenced for four charges of assaulting an emergency worker.
Joanne Hesse, prosecuting said Punshon was "distressed and hysterical" when she flagged down an ambulance shortly after 1am, Teesside Live reports.
The paramedics then sat her down to help, but she got up shouting "get off me", before "walking into the road trying to flag down cars" while continuing to shout at the crew.
When one of the paramedics tried to help further, Punshon "grabbed her hair", pulling out a clump.
The male paramedic intervened, but Punshon "lashed out" at the man's face with a "small blade that was attached to her keyring".

She caused an 8cm laceration to the paramedic's face, causing him to bleed.
Punshon then ran off and the police were called, who later tracked her down and arrested her.
The court was told that Punshon seemed "paranoid", and she "pulled away" from one of the officers and hit another in the face during the arrest.
She fell to the floor during the scuffle and then kicked one of the officers in the chest.
Ms Hesse said that even after being taken into custody, Punshon, who had no previous convictions, remained "aggressive".

Peter Hamill, defending, said Punshon, of High Hope Street, Crook, was "genuinely remorseful for what she's done" and made "full admissions" when interviewed.
He said she was "disgusted with her behaviour" and was "at a loss to explain" why she committed the offences.
Mr Hamill added there were "serious unresolved issues" and that she had been "drinking and using drugs to excess" at the time.
District Judge Helen Cousins said she accepted Punshon was remorseful but called it an "appalling" incident.
Punshon was given a 16 week prison sentence, suspended for 18 months and ordered to carry out 30 rehabilitation days.
She was also made subject of a 30 day community order and a 12 week curfew.
Punshon must also pay £250 compensation to the emergency workers and £85 costs.
